What does white or clear lights at the rear of a vehicle indicate?

1. The vehicle is turning left

2. The vehicle is in reverse

3. The vehicle is stopping

4. The vehicle is accelerating

The correct answer is: The vehicle is in reverse

White or clear lights at the rear of a vehicle indicate that the vehicle is in reverse. This signaling is crucial for safety, as it alerts other road users that the vehicle is backing up. When a vehicle is shifted into reverse, the lights come on automatically to provide visibility and to communicate the intent of the driver to those who may be nearby, such as pedestrians or other vehicles. This is important in protecting others from potential accidents, as not all vehicles come with driver observation that allows them to see everything around them when reversing. Therefore, other road users can take appropriate actions, such as keeping a safe distance or moving out of the way, when they see the white or clear lights illuminated.
