When must ground vehicle lights be activated?

The appropriate time for activating ground vehicle lights is from sunset to sunrise or in poorly lighted areas. This requirement is crucial for safety, as proper lighting helps ensure that vehicles are visible to others on the road, especially in low-light conditions. This visibility is vital to reducing the risk of accidents during nighttime or in locations without sufficient ambient light. Maintaining awareness of surroundings and ensuring that vehicles are easily seen can significantly contribute to safer travel.

Although other circumstances, like heavy traffic or foggy conditions, may also suggest the use of vehicle lights, they are not the primary criteria for when lights must be activated and may not apply universally. Therefore, the requirement of using lights during the specified times and conditions maximizes safety for all road users.
