Except for emergency cars, stopped or delayed vehicles to signal a traffic hazard, funeral procession vehicles, and vehicles going slower than 30 mph, the usage of hazard lights while driving is prohibited. Driving with hazard lights on is considered "displaying fraudulent equipment" and is punishable by a fine of up to $1000 in Virginia.
In addition, drivers who use hazard lights as a means of disguising their identity, attempting to stop police from seeing them committing other crimes, or providing warning to others are all breaking the law. Drivers who use hazard lights to avoid road blocks may not be able to prove that they had legitimate reasons for doing so, which can also result in fines or jail time.
Drivers who use hazard lights to communicate with each other are not violating any laws unless they use them too frequently or for too long of a period of time. However, if other motorists feel like it's causing them harm then they have the right to report you to the police.
Illegal uses of hazard lights include: using them to signal when you aren't in danger (such as waving down cars at intersections), using them to disguise your identity (such as wearing hazard lights when you're not in an accident), and using them to warn oncoming motorists (such as weaving in and out of traffic while flashing your hazard lights).
Driving with your hazard lights on is unlawful in the state of Florida. Hazard lights are only for cars that have come to a complete stop. The only time Florida drivers are permitted to activate their danger lights is when their vehicle is part of a funeral procession. Other than during a funeral, anyone seen driving with hazard lights on can be fined.
The use of hazard lights is important in letting other drivers know that you may have an emergency situation developing behind you. They also let other drivers know that you, yourself, are not in any kind of danger. This is very important because without warning signs or enough time to react, another driver might not take the time needed to avoid hitting you.
Using hazard lights for other reasons is illegal in Florida. This includes using them as a form of protest or to attract attention. They are also used when parking in a handicapped spot, so it's important not to use them where they aren't necessary.
People who break these laws should understand that they have put others in danger by causing unnecessary panic. Others drivers will not see your hazard lights until it is too late, and this can lead to accidents. If you are found guilty of violating this law, you could receive a fine between $60 and $100.
You may not use danger warning lights while driving, except to alert vehicles behind you if you abruptly slow down on a highway or unrestricted dual carriageway. Never, ever utilize hazard warning lights to justify unsafe or unlawful parking. Doing so could result in a ticket from the police.
Hazard lights are used to indicate that someone needs assistance and should be able to provide it. They are required by law to be placed on any vehicle involved in an accident that has damage to the body or frame. The lights must be mounted high enough to be seen by other drivers, but can be attached to the front or rear of a vehicle. They can also be placed inside the cab of a truck or van with the interior light turned off. These lights are known as "auxiliary" or "passenger" lights. Any other type of lighting is considered "extra." It is recommended, but not required by law, that you use the same number of hazards as there are people injured in the accident. For example, if three people are injured, you would need to use three separate warnings.
Using proper signaling techniques is important for efficient traffic flow. The use of improper or absent signals can cause accidents due to drivers being forced into dangerous maneuvers to avoid hitting the non-signaled driver. Proper signalization includes both visual and audible components.
Hazard lights can actually limit visibility, giving the impression to other vehicles that you are stopped or stalled. They make it impossible to see whether drivers ahead of you are tapping on the brakes, and they prevent you from using your turn signals. In rainy conditions, not being able to see clearly behind you may cause you to crash.
Drivers in all states except Vermont and Washington are required to turn off their hazard lights when not needed so that they do not interfere with other drivers' ability to see them. This is called "flashings" and requires special equipment installed on the driver's side rearview mirror. Failure to remove your hazard lights after stopping can result in a traffic violation or an accident.
If you are caught without your hazard lights on, you will be issued a warning for the first offense. A second offense within five years will get you fined $50-$100 in most states. A third offense within ten years will get you arrested for driving with hazard lights on.
The fine for not having proper flashings has ranged from $15 to $200 in different states. The fine for not removing your hazard lights after stopping has ranged from a warning to a fine of up to $1000.
In Virginia, only emergency personnel have the authority to use hazard lights. All others must switch their lights off when not in use.
The only time hazard lights should be utilized is when you are pulled over on the side of the road for any reason, or when you are in an emergency scenario, such as when you suffer a mechanical breakdown or abrupt loss of tire pressure and need to bring the vehicle to a safe stop.
Other than these situations, your best course of action is to keep the hazard lights off until you are ready to proceed again.
Section 307.100: Other than headlights, flashing signals are forbidden except on certain vehicles; punishment. Other than to indicate a right or left turn, warning signs are forbidden on other motor vehicles, motorbikes, and motor-drawn vehicles. Penalty for infractions 307.120.
Flashing lights are illegal unless specifically allowed by statute or local ordinance. Using flashlights as indicators is prohibited by state law in Missouri. This means that if you are driving down the road and see another driver's flashlight shining into your eyes, you have the right to assume that they want to make a turn, change lanes, or some other dangerous activity is happening behind the wheel. The same thing goes for motorcycle riders who use their headlamps or taillights to signal others; they are doing something illegal and could get pulled over by a police officer.
There are several exceptions where it is permitted to use emergency lights. For example, officers can use their sirens to get the attention of drivers before they pull them over for a traffic stop. There also many situations where drivers are required by law to use their lights while driving through towns at night. For example, when turning off of a highway, an officer must use his or her lights to alert other drivers that there is going to be a delay in traffic so they can move over to allow room for the vehicle to pass.
