When is it mandatory to use hazard lights?

Using hazard lights is an important safety feature that alerts other drivers to potential dangers involving your vehicle. It is mandatory to activate hazard lights when your vehicle breaks down or becomes a hazard on the road. This action serves multiple purposes: it signals to other drivers that your vehicle is not operating normally, it helps prevent accidents by making your vehicle more visible, and it indicates that there may be an obstruction or issue that drivers need to navigate around safely.

When a vehicle is disabled, parked in a no-parking zone, or experiencing an emergency situation, activating the hazard lights ensures that other motorists are aware of the potential danger, thus allowing them to take caution. This regulation aids in promoting safety on the roads, reducing the chances of collisions or misunderstandings between drivers.

In contrast, using hazard lights all the time while driving or only at night is not a safe practice, as it could confuse other road users regarding your intent. Similarly, while parking in a no-parking zone is discouraged, activating hazard lights in that scenario does not comply with the concept of notifying others of a breakdown or hazard.
