Use of Headlights and Horns
- 1/18When driving at night
At night, visibility is limited, and your headlights determine how far ahead you can see. If you are driving too fast, you may not be able to stop in time for an obstacle or hazard.
If your driving after sunset or before sunrise
The traffic law mandates headlight use from 30 minutes after sunset to 30 minutes before sunrise to ensure your vehicle is visible to others and to improve your visibility on dark roads.
People or vehicles are not clearly visible at 1,000 feet or more
In low visibility conditions like dusk, fog, or heavy rain, you must turn on your headlights even if its daytime, as this helps other drivers see you and reduces the risk of accidents.
To avoid temporary blindness from oncoming headlights
Shifting your gaze down and to the right helps you maintain orientation without being blinded.
Approaching an oncoming vehicle within 500 feet
Low beams prevent your headlights from blinding other drivers, which improves safety for both vehicles.
When following a vehicle within 300 feet
Using high beams when following closely can reflect off the vehicle ahead and impair the other drivers vision through their mirrors.
If you are driving on a lighted road at night
Street lighting improves visibility, so using low beams prevents unnecessary glare and keeps roadways safer for all users.
To maintain safe visibility in fog, heavy rain, sleet, snow, or dust
High beams can reflect off particles like fog or rain, making it harder to see. Low beams reduce glare and provide better illumination in such conditions.
When parking on an unlit highway at night
This ensures that your parked vehicle is visible to other drivers from a distance, reducing the risk of a collision.
To avoid dazzling other drivers
Streetlights provide enough illumination, and using high beams can cause glare, impairing the vision of oncoming drivers.
To prevent a collision at night
Your headlights limit your field of vision, so driving faster than what they illuminate can result in not spotting hazards in time.
To be visible during dawn or dusk hours
During twilight, natural light may be insufficient for other drivers to notice your vehicle, increasing the chance of being involved in a crash.
When driving through smoke, dust, or blowing sand, you must use
Like fog, these conditions scatter light from high beams and reduce visibility. Low beams provide better clarity and reduce glare.
The appropriate response when a large vehicle merges into your lane and you are in its blind spot
When you cannot safely steer away or stop, honking quickly can alert the truck driver to your presence and prevent a sideswipe or crash.
The correct driver response if a pedestrian is crossing at an intersection
Honking at law-abiding pedestrians is unnecessary and can be considered aggressive.
A safe alternative to honking in non-emergency situations
If you can safely adjust your position or slow down, it is better to avoid honking altogether. This reduces stress and avoids escalating tension on the road.
The legal rule for honking
Honking without a safety reason may violate noise pollution laws. Using the horn aggressively can lead to criminal charges under public disturbance regulations.
One reason why vehicles must be equipped with a working horn
The horn is an essential safety device that allows drivers to signal danger when other forms of communication are not possible, such as during brake failure or poor visibility.
