Final answer:
When your vehicle breaks down at the side of the road, you should activate your hazard warning lights to alert other drivers of your situation and avoid causing confusion or an accident.
Step-by-step explanation:
If your vehicle breaks down at the side of the road, you should turn on your hazard warning lights. The hazard warning lights are designed to communicate to other drivers that you are experiencing a problem and your vehicle is stationary, which can help prevent accidents. Turning on the right indicator could be misleading as it implies an intention to move to the right, and having your headlights on full beam is not advisable as it can dazzle other road users at night. Always ensure your safety and the safety of others by positioning your vehicle away from traffic if possible and setting up a warning triangle at an appropriate distance to alert oncoming traffic.
