If your vehicle is disabled on the highway at night, you should do what?

When your vehicle is disabled on the highway at night, pulling your vehicle as far off the roadway as possible and leaving the parking brakes on is the safest course of action. This ensures that your vehicle is not a hazard to other drivers, minimizing the risk of a collision. By moving off the road, you create a safer environment for yourself and other road users.

Additionally, utilizing the parking brakes prevents your vehicle from rolling or moving unexpectedly while you wait for assistance. This action brings a degree of security to the situation, allowing you to focus on calling for help without worrying about the vehicle moving into traffic.

Turning off your headlights would not be advisable, as it could make your vehicle less visible to oncoming traffic. Staying in the vehicle can be a reasonable choice, especially if it's unsafe to exit; however, the emphasis should be on ensuring the vehicle is out of the flow of traffic. Leaving the vehicle in the middle of the road is dangerous and against safe driving practices.
