Hazard lights are one of the simplest features in any car, yet drivers don't always agree on when they should be used. Some switch them on whenever it rains heavily, others use them to say thank you after being let into traffic, and plenty of motorists seem to think they're a convenient way to park wherever they want.
But those flashing amber (or red) indicators have a much more important purpose: warning other road users about a potential danger. Knowing when to activate your hazard lights can make a difference in an emergency, particularly when your vehicle breaks down, traffic suddenly slows, or you're forced to stop somewhere unexpected. However, using them incorrectly can confuse other drivers and even result in a traffic violation.
