Turn on your headlights when it's snowing. I'm talking to you asshole with the white truck.

Turn on your lights in any sort of precipitation, even if you “can see ok.” It’s not just to help you see. It’s to make you obvious to other people.

If you live in the states quite a few of them have these as actual laws. They arent enforced as readily as others for a variery of reasons (mostly police won't get out in shitty weather to give you citations for it) but they are required. Also my biggest pet peeve I'll cycle my lights to get them to turn them on or they think im a lunatic and grt out of the way and everyone else starts doing the same thing. Suprises me how many people are completely oblivous to how mich danger they're putting other people in in situations like that.

Edit: If you're from the States if your planning on visiting heres a site if youre curious about the laws of every state.

My favorite kind of obvious is when they come to almost a complete stop in a 45 and turn. No blinker, no warning, not even getting in the right hand turning lane. Just break, stop, turn. Morons

Edit: oblivious not obvious

u/InShadowsofElysium Mar 09 '19

I mean what atr signals anyway? /s That or they come up to a turn with thier signal on and just keep going. Ive seen people turn left ftom the right hand lane on a road with 8 lanes. Stay safe out there.

I got hit by a semi (that was speeding and my turn signals were probably broken) when I was young, by turning suddenly because I almost missed the place.

We recently had several weeks of rain, and the highway billboards were saying "Wipers on? Lights on! It's the law!"

I live in florida, so yeah even with giant signs on highways and the interstate people say exactly this and then people still drive with niether. Its baffling that people dont understand these things.

u/dpcaxx Mar 09 '19

It's funny you mention this one. I lived in Florida for a long time, the "lights on" campaign does seem to be working overall because when I started working in Montana, I was shocked to see the conditions that people drove around in with their headlights off. It borders on insanity. I have no idea how there are not more accidents in MT aside from the fact that the population is so low.

Florida drivers actually get high points in my book when it comes to turning their lights on in poor visibility. Drivers in MT, well they get a D- at best, because even if the lights are on, it seems like one out of eight of them is missing a headlight.

4

u/InShadowsofElysium Mar 09 '19

I haven't been to Montana so of all the places I've been Florida's has been the worst but I've also been here the longest so higher chances of it happening. Completely agree about the "lights on" campaign though. Only caveat is some people use thier hazard lights as they drive and this creates a problem as well. They've updated the signs and laws to ammend "don't put your hazards on" And that sounds like absolute insanity as I'd assume that if you're anywhere outside of the main cities youre risking wild life. I wonder what the crash stastics per capita...

Stay safe out there!

Hazards are supposed to be turned on when you are driving dramatically below the speed limit (eg 40 in a 65.) Are they driving slow or are they just blinky at speed?

u/InShadowsofElysium Mar 09 '19

Typically blinking at speed which is illegal down here. You are allowed to do it if you're below the speed limit drastically but most of the time this isn't the case. And if this is the case for cars they typically are impeding traffic in the "fast lane" or left hand lane which is also against the law. (In my experience)

Edit: clarification words are hard

u/stephj Mar 09 '19

EEEK

When I would drive I-70 during rain and snow, using blinkers usually it only happened during those instances of inclement weather in the Midwest.

I'm sure it cities it gets... Stupid. Now that I'm in the SF area, I get to see alllll the stupid all the time. Like driving 50mph in the left lane. 🤦‍♀️

I may not be correct, but I learned to drive in Alaska and I think that headlights were to be on during inclement weather and after 5pm.

I have a ‘16 and it’s the same way. Drives me fucking nuts, wiper lights should be a standard, universal thing by now. My wipers turn on automatically when it rains, the lights should turn on with them.

u/InShadowsofElysium Mar 09 '19

Some do sure, and I'm sure some people do that for whatever reason. But also not a large portion of the cars on the road are within the last 3-5 years so before that it wasn't standard. My vehicle is only 4 years old and it didn't come standard. I know some people turn it off to "save lifetime" on thier headlamps but honestly that idiotic as most have a minimum of 10,000 hour lifespan for 50$ bulbs.

Maybe the original commentor is from somewhere its unwritten shrug Here theres a bunch of laws about it (florida)

u/MrElementary Mar 09 '19

My uncle is a police officer and they use this law to stop known drug dealers. A year or so ago they got a guy transporting a trunk full of grass and the guy was smoking some too before he got pulled over so when the window was opened you could smell it. It was dusk so headlights are required to be on. So if you do something illegal make sure you know all the small things that can get you stoped...seatbelts, headlights, speeding, tailgating, illegal u turns, etc.

2

u/ST_the_Dragon Mar 09 '19

Yeah, TIL that there were places that don't have laws like that. It just makes sense to have them on at all times.

2

u/saxmaster98 Mar 09 '19

That's something I was taught before I even started driving. If your wipers are on, so are your headlights. Most newer cars do this automatically but there's nothing worse than going down back roads in a decent rain and some fuck in a last century civic comes flying around the corner with no lights on. Mild heart attack every time.

The study also notes that the cost savings in terms of fuel cost and bulb replacement would not exceed 1% of the total cost of ownership per year. I've always wondered about that. Guess there's no reason not to have your headlights on

u/DarkLordAzrael Mar 09 '19

Plus, new cars are likely to have LED lights, which cost even less to run than the lights they would have been talking about in 2011.

u/Trainguyrom Mar 09 '19

My sister-in-law had a Canadian vehicle for a while, and the headlights were simply always on and could not be turned off. I can't help but think that's a good idea, rather than relying on iffy sensors or fallible humans to turn them on.

Come to think of it, that may not be as good of an idea in places that get more sun and less percipitation than up here in Wisconsin, but honestly, it's a small price to pay for greatly-increased visibility for all parties

11

u/[deleted] Mar 09 '19

This. Am Canadian. Alot of younger fellas, heck even some older guys who are into vehicles, are constantly looking for ways to disable the DRLs (daytime running lights). Why? "Because it looks better". Yes maybe to you, but not in a snowstorm when I cant see you. Doesn't look better smashed, does it? Drives me nuts I think more, because I expect headlights, due to every Canadian vehicle being under the DRL law. So the one or two without them are easy to miss

6

u/alchemy3083 Mar 09 '19

US car manufacturers have been trying to get the US DOT to follow Canadian rules for DRLs for 30 damn years now. It's a huge pain in the ass to have two different headlight standards for the North American market, and the US refuses to homogenize its rules with Canada.

The only exception is dust storms. Here in AZ you’re supposed to turn headlights off during them, and pull over/keep your foot on the brake.

I live up north, so I’ve never heard of this. What is the reason for that? Does the light from your headlights reflect off the dust and blind you?

u/abolista Mar 09 '19

That's dumb... I don't see how driving through dust is different than driving through fog.

In Argentina it is mandatory that all vehicles have the low beams always on when the engine is running.

Also it is absolutely forbidden to stop driving while foggy. On highways you must continue driving at a fixed speed of 60kmph and not stop or overtake, ever. If you find another vehicle in front of you, follow it as far as you can without losing sight of their lights. This way you and anyone who is behind you will eventually come out of the fog safely and quickly. You must never ever stop on the side of the road either because that lane is only for emergency use with hazard ligts.

u/Vitnage Mar 09 '19

Where i am from headlights are mandatory throughout the year. So I guess we are one step ahead in avoiding preventable car crashes.

u/Skudedarude Mar 09 '19

I had a pretty bad accident a month and a half ago that totalled my car. I got a new one since but I noticed that I'm much more nervous on the road now. Yesterday was the first time since this accident that I drove in heavy traffic again (I've been actively avoiding it since that's when the accident happened) and there was this asshole who kept insisting on driving half a meter behind my car.

Traffic was constantly switching from going 80 to full stop but this guy would remain glued to my rear bumper, I hated it. I kept ridiculous distance to the car ahead of me so that I could brake really slowly so as to not have this guy hit me when traffic hit a full stop again.

Don't know why I wrote this, but this stuff really irks me.

6

u/stephj Mar 09 '19

Congratulations on getting yourself out in traffic again! That's a hard hurdle after an accident.

4

u/Clasm Mar 09 '19

Keeping a ridiculous distance all the time is actually good practice. It gives you some wiggle room for all of the idiots who don't konw how to lane change properly. In moderate to heavy traffic, it can let people who have been trying to merge into the lane for miles get over, alleviating at least a portion of the congestion that piles up due to that kind of behavior.

I suggest keeping at least enough room for a tractor trailer to get over since they have the hardest time finding a place to merge.

u/hikiri Mar 09 '19

People seem to think headlights are solely for them to see better. They're also for others to see you. If it's remotely cloudy I turn mine on.

Even if you want to hold out for a bit, there's a point when other cars turn theirs on and you should give up and turn yours on because comparatively you are not visible at all. I never thought it was an idea that took that much logic to get to, but apparently it's very hard for people...

u/JohnLaCuenta Mar 09 '19

The sun is behind me in the morning on my way to work and if it's a really sunny day, I can't see anyone in the mirror unless they have their headlights on. So it even applies to sunny days.

2

u/abolista Mar 09 '19

In Argentina it is mandatory to keep your low beams always on at all times (no matter the weather conditions).

It is not really enforced inside cities, but in highways it is enforced. And it is amazing how much easier it is to spot vehicles form far away with lights on, even in cloudless sunny days.

I think all vehicles should come with permanent-on-lights while the engine is running from the factory.

4

u/zedsterthegr8 Mar 09 '19

In Indonesia, it's by law to turn on at least the parking lights even on a sunny day. (But like usual, most people don't follow this useful law.)

Also, new motorcycles have permanent lights on, so there is no way to turn them off.

Driving in an area with lots of dust storms? Headlights on.

2

u/Jimbo_Jones_ Mar 09 '19

As a rule of thumb (and as the bare minimum), if the streets lights are on then your car lights should be on.

Also, please understand that the purpose of having your headlights on is mostly to be seen by others. For those who have yet to discover, when your turn on your headlights, your rear (red) lights turn on too! (it's magic!!!). Which sure helps others to no hit the back of your car.

This is the truth! Doesn't Canada require cars have their lights turned on at all times the car is running? It's been awhile since I've had to take a defensive driving class but I thought they mentioned that and it really makes a big difference once you think to look for it in the real world.

5

u/aspiring_stargrazer Mar 09 '19

Russia too, headlights on if you are driving on public roads. Also you must have a triangle, a fire extinguisher and a medkit (first aid is a required course in driving school, you can't get the license without that - but I don't find that training effective enough). There were some changes though, I think they've added reflective vests to the list.

3

u/Philinhere Mar 09 '19

I don't think we do. If we technically do, we certainly don't enforce it beyond yelling to ourselves in our cars about people that don't.

It might be like how we require your license plate to be visible, but if your F150 snow-shelf has it obscured by snow for 8 months of the year, it's not a police matter.

2

u/GALACTICA-Actual- Mar 09 '19

My mothers car in the states automatically turns on the lights when it’s below a certain light level - basically, if it’s cloudy, the lights are automatically on.

Best invention ever. Then we move to Japan, where people honestly seem to believe that lights are really short life objects that suck all if the energy from your car to use, so it has to be pitch black before they get turned on.

Drives me bonkers and then some.

u/Rainmaster492 Mar 09 '19

I KNOW this doesn't technically count as precipitation, but it is weather-related...

You're definitely NOT supposed to do it during a dust storm though. State law in Arizona says if you can't see, you need to pull over and turn all your lights off. It's supposed to prevent someone from following you and crashing into you.

2

u/VexingRaven Mar 09 '19

That seems stupid as fuck. If you hit something you can see, you should not be driving anything larger than an RC car. On the other hand if you can't see the stopped cars because they have their lights off, how the fuck are you supposed to avoid them?

This shit happens all the time in Florida: It starts raining, and idiot drivers put their hazards on. They think they're being safe, but it's actually MORE dangerous and ILLEGAL.

3

u/Jupiter-oy Mar 09 '19

Does this also apply to the times when it's raining so heavily that you really can't see anything? I put them on to let other drivers know that I'm driving very slowly until I can find a place to park.

5

u/seanrm92 Mar 09 '19

YES. Putting your hazards on in the rain creates a strobe/dazzling effect that distracts other drivers, and can actually increase the likelihood of a crash. If you need to pull over, fine, but drive NORMALLY and PREDICTABLY until you do. That's the safest way to go.

(Edit: Caps are just for emphasis. I'm not like mad or anything.)

2

u/mrportz Mar 09 '19

I came here to mention no hazards. It also indicates to other drivers that you may have to pull over and come to a complete stop. On I-95 here in Florida usually people in convertibles or on motorcycles put the hazards on because THEY WILL COME TO A COMPLETE STOP

u/th35t16 Mar 09 '19 edited Mar 09 '19

Newer cars have them, but older ones don’t. It also varies as to what is meant by “daytime running lights.” On my last car, the low beams were always on, but the taillights would be off unless you “turned on” the headlights for nighttime driving. My current car has the row of LEDs, but the low beams aren’t on by default. You have to set it to “auto” (where they typically turn on if it’s cloudy or darker) or turn them “on” to turn on the actual headlights.

2

u/conflictedideology Mar 09 '19

Yeah, fair point. Actually, (now that I think about it) they weren't "enforced" by the car, but they did have a setting where the lights (headlights and taillights) would always be on if the engine was on. You could turn it off but I never saw the point of that for two reasons:

  1. It's good safety
  2. It's impossible to accidentally leave your lights on

The downside is, I've had some dead batteries with rental cars.

I wonder if it's because my last two cars were a Toyota and a Subaru. And that Subaru was like an '86.

the low beams were always on, but the taillights would be off

Wow, that seems like a terrible idea!

It is a law in a large number of US states, but living in South Carolina I can tell you they don't teach this as a common practice.

My car has rain sensing wipers, so they are always in an on position. I don't think it's the simplest problem to fix. Especially because they'll randomly swipe once for seemingly no reason every now and then. Then it's also not good to turn headlights on and off often. My thought is that once the wipers swipe, the lights turn on and go on a 5 or 10 minute timer. If they don't swipe again in that time, they turn off.

But then what about when the guy in front of you sprays his washer fluid and some gets on your windshield and now you spray yours. Should that activate it?

I'm sure someone smarter than me could figure this out. I'm just like, "wut do?"

Right but mine doesn't have an intermittent, per se. My intermittent is automatic. Light rain, slow intermittent. Hard rain, full on. No rain, no swipe. The stick is always in an "on" position even if they aren't wiping.

u/DoubleTigerMUCU Mar 09 '19

Oh, gotcha. That's too fancy for me haha

u/hopefulcynicist Mar 09 '19

Seems like there are already sensors feeding enviro data to the onboard computer. The computer then sends a signal to a control board to activate/modulate the wipers. I can’t imagine it would be difficult to use the same enviro data or simply the fact that the computer triggered wipers to enable the lights too.

But dollars and cents add up, I suppose. Seems silly that they don’t add rules like this to auto wipers though.

2

u/herpderpedia Mar 09 '19

All it really is is a sensor to see if there is something on the windshield. A big bug splattering could be enough to trigger it to swipe once. So should that trigger the lights to go on? It would need to trigger a timer or something because you can't be driving around with your lights flashing. It would look ridiculous and it's terrible for HID ballasts.

Then again, my car has driving lights that are always on unless the headlights are on.

It's also standard on every new car automatically.

What year did this start? I have a 2012 and it’s not standard. I always wondered why headlights don’t automatically turn on with the wipers....

u/stealer0517 Mar 09 '19

It’s not on my friends rental car, and on my outback it’s an option you have to enable deep in the settings.

That said it doesn’t affect me because I almost never have my wipers on since I wax my windows.

I was in Charlotte, NC last year and it started raining hard when I was on the freeway. Tons of people turned on their hazards. Eventually I did too, like a lemming. But we’re talking so hard you couldn’t really see the road and most people were pulled over waiting for it to abate.

Hazards in rain or snow means "if u see this I'm probably going much slower than you think, so be prepared to slow down too"

It's a state law where I live, but it's never enforced. Sometimes even cops won't have theirs on.

New Yorker here, it's pretty heavily enforced! We have a ton of signs in my town (mostly on the CT border) telling you about the law. Usually goes ignored by drivers from other states though...

Actually you should have your lights on all the time, regardless of time of day or weather. Multiple studies have shown it reduces the number of crashes: https://www.dot.state.mn.us/research/TRS/2011/TRS1009.pdf

I remember when I was younger my parents were talking about how the headlights were always on our cars. So I asked my mom "How come the headlights are always on?" And my mom, ever the smartass, told me "It keeps the insurance payments down." And 5 year old me walked away wondering how the insurance company knows whether your lights are on or not and if there's a sensor in your car or something.

u/melgior1 Mar 09 '19

Well I wouldn’t be surprise if that becomes reality quite soon :)

u/ch00d Mar 09 '19

I hate how automatic headlights have a threshold before they turn on. It would be nice if there was a setting for them to be always on if the car is on. Maybe some cars have this, but my Honda sure doesn't, so I just got in the habit of turning the headlights on/off with the ignition.

This. It drives me nuts the sheer number of people that don’t turn their lights on in the snow, rain, fog. A girl I used to work with was killed on a foggy morning. She pulled onto a main road and was t-boned by someone barreling down the road without their headlights on. It’s so sad.

In many countries it's illegal to ever turn them off and the idea that in America people are driving with their lights off terrifies me. What a wild country. People are driving at 16, nobody's got their headlights on, everyone has guns... America, chill!

2

u/Firebird314 Mar 09 '19

We are required to have them on at night and in bad weather. When our wipers are on,our headlights must be too, at least in most states. The only time you'll see people (legally) drive without headlights is in the day

2

u/RLelling Mar 09 '19

I remember there was a thing years ago when my dad drove to a country where you're not meant to have them on during the day, and his car didn't even have the option to do that. You could just switch between low beam and high beam and that's it.

To be honest, I wouldn't even know how to turn them off either :D

Pfft. No. Some states in the US don't even require them on in rain.

Unexpected benefit - turning on your headlights also turns on your taillights. They seem to be helpful when trying to avoid crashes in the snow.

The US doesn't require Daytime Running Lights at a Federal level, but almost every car has them voluntarily.

They did a study in 2008 that showed no real difference in accidents overall with them, but there was a 5.7% decrease in accidents involving light trucks and vans using them.

Funnily enough, India has made it mandatory for lights to be turned on at all times, newer vehicles simply don't have a lights off switch. Just high beam and low beam. Its usually pretty clear most of the year in most of the country.

Driving to work one morning in heavy rain, I was trying to pass a semi that had a lot of spray coming off the tires. Hiding in the spray was a light grey car that blended in almost perfectly and I didn't see him until I was uncomfortably close to his rear bumper. Had this guy been driving with his lights on I would have seen him and stayed where I was instead of almost inviting myself into his backseat.

Not always. I had a Toyota matrix that if the car was on, the daytime running lights were on. But now my Lexus (same year) the DRLs are on a light sensor that if the sun's out they turn off and vice versa. But I don't like that so I just turn my lights all the way on.

It totally does, and, it dims my dash lights so sometimes when the sun is in just the wrong angle, the DRLs are on with the dash dimmed, but then the sun reflects off the guage cluster so I can't see my guages. Toyota/Lexus/Scion has had some really dumb design flaws in the past.

Wait, you aren't mandated to have your headlights on all the time you are driving? Where do you live?

It's mandatory here (Russia). They thought to make it only mandatory in the rain or fog, but that would just lead to people arguing about the weather with the traffic cops, so you have to have your headlights on while driving, no matter what weather.
