Why is it important to turn on your hazard lights during engine trouble?

Turning on your hazard lights during engine trouble serves a critical safety function by alerting other drivers to your situation. When a vehicle encounters problems and may be unable to move or is moving slowly, activating the hazard lights communicates an immediate message to other road users that you are experiencing difficulties. This visual signal prompts other drivers to exercise caution, maintain a safe distance, and be prepared for any unexpected movements or potential hazards.

Using hazard lights can help prevent accidents by increasing visibility and awareness on the road, especially in poor lighting conditions or during adverse weather. This practice is a vital part of road safety protocol, ensuring you and other drivers are more informed about any potential dangers in the vicinity. The other options you mentioned do not pertain to the practical safety benefits of using hazard lights in such situations.
