When you are parked at the side of the road at night, you must

Switch off all lights
Leave the vehicle unattended
Turn off the engine
Turn on your 4-way flashers to warn others

The correct answer is: Turn on your 4-way flashers to warn others

When parked at the side of the road at night, it is crucial to turn on your 4-way flashers to warn other drivers of your presence. This action enhances visibility and indicates to approaching vehicles that your vehicle is stationary, thereby helping to prevent potential accidents. Safety is a top priority, especially during low visibility conditions at night. Turning off all lights is not advisable as this could make your vehicle less visible to other drivers. Leaving the vehicle unattended is generally not a safe option, especially on the side of the road where it might pose a hazard. While it is a good practice to turn off the engine, it is not specific to nighttime parking and does not directly address the need for visibility, which is paramount when parked on a road at night. Thus, activating the 4-way flashers is the most appropriate action for ensuring safety and visibility.
