When driving at night, what type of headlights should you use whenever it is legal?

Using high beam headlights when driving at night is the best option when it is legal to do so, as they provide the greatest illumination of the road ahead. High beams are designed to cast light further and brighter than low beams, which helps in identifying potential hazards, obstacles, or pedestrians at a greater distance.

It's essential to use high beams in areas without streetlights or in rural settings where visibility is generally poorer. However, drivers must be aware and switch to low beams when encountering oncoming traffic or following closely behind another vehicle. This courtesy prevents glare and ensures safety for all road users.

In contrast, low beams are suitable for situations where there's oncoming traffic or when conditions require reduced brightness. Fog lights are used specifically in foggy conditions to enhance visibility close to the ground. Parking lights are intended for use when the vehicle is stationary and should not be relied upon for nighttime driving. High beams, therefore, maximize visibility when conditions allow, making them the ideal choice for safe nighttime driving.
