Philadelphia Drivers License Practice Test

If your car is disabled and you are forced to drive less than the posted minimum speed, what should you do?

1. Drive without lights

2. Turn on your parking lights

3. Drive with your emergency lights flashing

4. Move to the shoulder of the road

The correct answer is: Drive with your emergency lights flashing

When a vehicle is disabled on the road, especially in situations where driving at the posted minimum speed is not possible, it's crucial to signal to other drivers that your vehicle is not functioning normally. Driving with your emergency lights flashing serves this purpose effectively. It alerts other drivers to your presence, indicating that they should exercise caution when approaching. This is especially important in low visibility conditions or at night, as it helps prevent accidents by making your car more visible to others on the road. Using emergency lights provides a clear visual signal that your vehicle is not moving at the expected speed or may even be stopped, facilitating safer navigation for both you and surrounding motorists. While other choices may provide some level of visibility or signal, they do not communicate the same level of urgency or hazard that emergency lights do.
