In what situation should you activate your hazard lights?

Activating your hazard lights is appropriate when pulling over for an emergency because it signals to other drivers that you are experiencing an issue and may not be able to move your vehicle safely. This alerts surrounding traffic to exercise caution and navigate around your vehicle safely, helping to prevent potential accidents. Proper use of hazard lights in emergency situations enhances visibility and can provide additional safety for you and other road users.

The other situations mentioned do not align with proper hazard light usage. For instance, using them only when parked might lead to confusion about whether a vehicle is disabled or not. Keeping them on at all times while driving can distract other drivers and contradict the intended purpose of hazard lights. Similarly, turning on hazard lights when entering a roundabout may not be appropriate, as it could mislead other drivers about your intentions on the road. Overall, hazard lights should be used thoughtfully to communicate specific situations effectively.
