When should you use your hazard lights?

Using hazard lights is an important safety measure when your vehicle poses a temporary hazard to other road users. This includes situations where your vehicle might be stationary, such as if you experience a mechanical failure or are involved in an accident. Activating your hazard lights alerts other drivers that they need to exercise caution around your vehicle, helping to prevent further accidents or confusion on the road.

In contrast, using hazard lights when parked does not provide necessary communication to other road users about potential hazards, especially if the vehicle is legally parked and not obstructing traffic. Driving in low visibility conditions does not necessitate the use of hazard lights while moving; instead, headlights are more appropriate for improving visibility. Additionally, using hazard lights when approaching a roundabout can confuse other drivers about your intended actions, as they indicate a stopped or slowed vehicle, which could be misleading in a dynamic driving situation.
