Hazard lights must be visible from at least __________ feet in daylight.

Hazard lights, also known as emergency flashers, are crucial for alerting other drivers to a vehicle that may be stationary or moving unusually on the roadway. The requirement for hazard lights to be visible from a certain distance is to ensure that drivers can adequately perceive and react to the situation, enhancing safety on the road.

The correct answer of 500 feet reflects the need for high visibility in various driving conditions, especially during daylight when other vehicles might be approaching at speed. Being visible from this distance provides ample time for approaching drivers to notice the vehicle and respond appropriately, whether that means slowing down, changing lanes, or preparing for potential obstacles ahead.

Recognizing the importance of visibility, the guidelines set a standard that ensures drivers are alerted to potential hazards well in advance, fostering a safer driving environment for all road users.
