When must you always dip your headlights at night?

Answer: B — When other vehicles are coming towards you

Dipping your headlights at night is essential to ensure the safety of all road users. When other vehicles are coming towards you, particularly with their headlights on, it can create glare that affects the ability of drivers to see clearly. By dipping your headlights, you reduce this glare, allowing oncoming drivers to see better and maintain their lane, which ultimately enhances safety for everyone on the road. This practice is part of responsible driving etiquette and is often mandated by traffic laws to prevent accidents caused by temporary blindness from bright headlights. Maintaining clear visibility for all parties is crucial, especially at night when visibility is already compromised.
