What type of lighting should cars use when parked on the highway at night?

When a vehicle is parked on the highway at night, it is essential to ensure that it is visible to other drivers while minimizing the blinding effect that could occur with brighter lights. Using parking lights or lower beam headlights provides adequate visibility of the parked vehicle to other motorists, reducing the risk of accidents. Parking lights are specifically designed to signal the vehicle's presence without creating glare.

High beam headlights are too bright for this scenario, as they can blind oncoming drivers and create hazardous conditions. Fog lights are intended for low visibility conditions, such as fog or heavy rain, and are not suitable for use when parked. While hazard lights indicate a vehicle is stopped or experiencing trouble, they do not provide the same level of visibility needed for a parked vehicle on a highway, especially in less illuminated conditions.

Thus, utilizing parking lights or lower beam headlights is the appropriate choice to enhance safety and visibility for both the parked vehicle and passing traffic.
