Is a driver required by law to dim the high beams when approaching another vehicle?

Answer: B — Yes, at a distance of 150m

A driver is required by law to dim their high beams when approaching another vehicle at a distance of 150 meters. This distance is established to ensure the safety and comfort of other drivers, as high beams can cause significant glare and affect the visibility of oncoming traffic. Dimming the high beams allows for a safer driving environment for everyone on the road, reducing the risk of accidents due to temporary blindness from intense light. Understanding the specific distance of 150 meters is important for drivers to adhere to traffic laws and promote safe driving practices. It ensures that drivers remain vigilant and courteous to others on the road, which is crucial at night or in low-visibility conditions. Keeping this distance in mind allows drivers to prepare for any necessary maneuvers without compromising the safety of others.
