When following a large vehicle at night, you should always?

Answer: B — Switch off your high-beam headlights

When following a large vehicle at night, switching off your high-beam headlights is essential for safety. High-beams can cause distraction and glare for the driver of the large vehicle, as well as for oncoming traffic. This is particularly important when you are closely following another vehicle, as their size and height may block your view of the road ahead and the lights of other vehicles. Keeping your high-beam headlights on would impair the vision of the driver ahead and can lead to dangerous situations. Increasing your speed to pass quickly may not give you enough time to ensure that the maneuver is safe, and staying close behind a large vehicle can limit your visibility of the road conditions ahead, increasing the risk of a collision. By turning off your high-beams, you ensure a safer driving environment for yourself and other road users, allowing everyone to navigate the road conditions more effectively.
