If your vehicle is disabled on the highway at night, what is the safest action to take?

Moving the vehicle off the roadway and turning on the parking lights is the safest action to take if your vehicle is disabled on the highway at night. This action helps you avoid further hazards associated with approaching traffic, as staying on the roadway can expose you to the risk of accidents. By moving the vehicle off the road, you create a safer environment for both yourself and other motorists.

Turning on the parking lights serves as a warning signal to other drivers that your vehicle is not in motion and may be an obstacle. This enhances visibility and alerts others to take precautions when driving nearby. Overall, this response prioritizes safety by minimizing the risk of collisions.

Additionally, the other options may increase danger rather than provide safety. For example, seeking help by walking along the highway can expose you to the risk of being hit by a vehicle. Staying in the vehicle can be safe if you cannot move it, but without warning lights or flares, you remain vulnerable to traffic. Lining the roadway with flares can be useful, but it may require you to exit the vehicle, presenting additional risks.
