I’ve been driving since the 70’s, and that’s outright bullshit. Whereas I was actually taught to flash my brights to let someone know they had left theirs off, I never even heard of flashing your lights to indicate that you deserve the left lane more than the person who’s already in it until the 90s.

(I have to admit, I see no purpose in paying for an article that is one journalist claiming another is wrong.) I won’t claim I’m old enough to have invented high beams, but the inventors clearly knew that while rural people, at least, would find them handy, they had to be turned off quickly, which allows flashing.

Using your high beams to signal intent to pass is codified in some states laws in specific circumstance. (See, for instance, California.) But I can’t see anything in, say, Illinois’ laws about it, and the rules of the road for Illinois, for example, only mentions “blinking your headlights” in the section about passing trucks.

What I mean is the same as you, clicking your high/low beams on and off with the flicker that is often on the turn signal wand. Depends on the make of the car.. in older cars it used to be a button on the floor that you operate with your left foot. Also… that you should mention European cars - I learned to drive in Germany… it is common and it is law… the flasher is used to signal the driver in front of you to move over as you intend to pass. Almost always on the autobahn. Obviously you would not do this on one lane roads (one lane in each direction that is). I’d be very willing to argue with any state trooper in any jurisdiction of the US who says that the flasher is for some other purpose. ---

I’ve already shown you links where in other jurisdictions it is allowed expressly for other purposes. See Wisconsin, for instance. Here is the statute: > [@](#): > > 347.12  Use of multiple-beam headlamps. > (1) Whenever a motor vehicle is being operated on a highway during hours of darkness, the operator shall use a distribution of light or composite beam directed high enough and of sufficient intensity to reveal a person or vehicle at a safe distance in advance of the vehicle, subject to the following requirements and limitations: > (a) Whenever the operator of a vehicle equipped with multiple-beam headlamps approaches an oncoming vehicle within 500 feet, the operator shall dim, depress or tilt the vehicle’s headlights so that the glaring rays are not directed into the eyes of the operator of the other vehicle. **This paragraph does not prohibit an operator from intermittently flashing the vehicle’s high-beam headlamps at an oncoming vehicle whose high-beam headlamps are lit.** > > (b) Whenever the operator of a vehicle equipped with multiple-beam headlamps approaches or follows another vehicle within 500 feet to the rear, the operator shall dim, depress, or tilt the vehicle’s headlights so that the glaring rays are not reflected into the eyes of the operator of the other vehicle. This paragraph does not prohibit an operator from intermittently flashing the vehicle’s high-beam headlamps as provided under par. > > (a). > (2) Subsection (1) (a) and (b) does not apply to the use of alternately flashing or pulsating headlamps under s. 347.25 (1r). Emphasis mine. Interestingly, no exemption there for flashing high-beams as a signal to pass. ---

There is an important difference between intended usage and what people actually use it for. It is very common to flash brights in order to alert oncoming traffic to various hazards. Whether this is the intended purpose of the feature and whether this is condoned by law enforcement is irrelevant to the OP’s question of what people use them for. I have personally been ticketed for flashing to warn about a speed trap :smack: ---

> [@awldune](#): > > There is an important difference between intended usage and what people actually use it for. I’m not convinced there was any “intended” purpose behind the ability to flash your lights. My guess–and I’d be happy to be shown otherwise–is that it’s just a signal that developed out of the design of the high beam mechanism on most cars, when they moved it to the steering column so it reacts like a turn signal. The same sort of signal can be conveyed by flashing your low beams on and off. I don’t think it has an inherent purpose, just something that naturally developed, like flashing your hazards or cab lights or headlights or whatever after passing a vehicle to say “thank you.” ---

Yup, your drivers ed course in NC knows the right answer. Tailgating and honking was the result of the person in front _not_ moving over to the right lane, and is more of a sign of aggressive driving than the asshole doing the honking and tailgating. ---

Cars going to other direction wouldn’t even notice. Sorry you got a ticket… but it is against the law.

(In the US, most multi-lane highways require 18-wheelers to drive in the rightmost lane or two.) These are the only two reasons I flash my lights at other cars. If someone flashed their lights at me and I already had my lights (and not my brights) on\*, I’d be very confused and not know what message they were trying to give me. If I was trying to change lanes/pass on a highway and they were behind me in the lane I was going into, I’d speculate that they were letting me know I could move over, but wouldn’t be sure, since I’m not driving a big truck. \*which I always do, because I never turn my lights off. They go off automatically when the car turns off. My husband’s car doesn’t do this and I hate it. ---

Flash, whistle, trumpet, cheese slices whatever!” 😕 What are you talking about? Where have I said anything about cops other than in my first post (where I agreed that flashing lights is a common signal indicating this, but did not opine about its legality) and the last one (where you specifically said it was illegal in all 50 states, which is factually incorrect. I can dig up more states and more cites that is legal in other jurisdictions, if you’d like, but that’s not a point I’m interested in arguing.) I’m arguing against your point that the only legal reason to flash your brights is to signal to pass is utterly, and factually incorrect. How many more citations do you need? You want something more recent? Let try November 2011 of this year [then](http://articles.orlandosentinel.com/2011-11-08/news/os-flashing-headlights-driver-wins-20111108_1_ryan-kintner-headlights-sanford-judge): > [@](#): > > Sanford judge: Florida law does not prohibit a driver from flashing headlights > > November 08, 2011|By Rene Stutzman, Orlando Sentinel > A judge in Seminole County Tuesday ruled that it’s perfectly legal for people to flash their headlights to warn other motorists of a speed trap ahead. But, once again, I really don’t give a shit about warning other motorists about cops. I don’t do that personally. I’m talking about other uses like flashing for lights out or to get someone to drop their high beams. ---
