What action should you take when parked on the side of the road?

Turn on your headlights only
Activate the four-way emergency flashers
Leave the car in gear without any signs
Place warning devices at least 20ft away

The correct answer is: Activate the four-way emergency flashers

When parked on the side of the road, activating the four-way emergency flashers is crucial for ensuring your safety and the safety of others. This action signals to other drivers that your vehicle is stationary and may pose a potential hazard. It increases visibility, particularly in low-light conditions or poor weather, alerting drivers to exercise caution as they approach. While turning on headlights can improve visibility, it does not communicate the same level of alert as the four-way flashers. Leaving the car in gear without any signs fails to warn other motorists, and placing warning devices, while important, is not a substitute for immediately communicating your vehicle’s presence through flashers. Being proactive in this way helps prevent accidents and promotes a safer driving environment.
