What is the visibility requirement for parking lights?

Answer: C — 500 feet to the front and rear

The visibility requirement for parking lights is set at 500 feet to the front and rear of the vehicle. This standard ensures that other drivers can see the parked vehicle well in advance, especially in low-light conditions or adverse weather. Visibility of this distance helps to prevent accidents by alerting approaching vehicles that there's a stationary object ahead. Regulations surrounding vehicle lighting are designed to enhance safety on the road, making it critical for drivers to adhere to these requirements when parking, particularly in dimly lit areas or on the side of the road.
