What is the requirement for headlights on the vehicle used during the road test?

The requirement for headlights on the vehicle used during the road test is that the headlights must have both high and low beams. This is essential because having both functions ensures that the driver can adapt to different driving conditions. Low beams are crucial for nighttime driving or in adverse weather conditions when glare from high beams could impair the vision of oncoming traffic. Meanwhile, high beams provide additional visibility in dark conditions when no other vehicles are present.

This requirement reflects the real-world necessity for drivers to understand how to use their headlights properly based on their environment. It emphasizes safety by ensuring that the learner is capable of switching between high and low beams as required, which is a critical aspect of responsible driving practices. The options that suggest headlights are only necessary under specific conditions or only one type of beam do not align with the comprehensive safety measures emphasized during the road test.
