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

Question

High-beam headlights

Parking lights or low-beam headlights

Emergency flashers or turn signals on the highway side

Answer 1

When parked on an unlighted highway at night, cars should use emergency flashers or turn signals on the highway side. This helps to alert other drivers to the presence of the parked vehicle, improving safety for both the parked car and oncoming traffic. Using parking lights or low-beam headlights may also be acceptable in some jurisdictions, but emergency flashers are generally the recommended choice for maximum visibility.
