Hazard lights should be used for what purpose?

• A. Normal driving in clear weather.
• B. A temporary hazard or when your vehicle is stopped.
• C. To replace turn signals.
• D. To signal a full stop on a highway.

Answer: (B)

Hazard lights are meant to warn other drivers about a temporary hazard or when your vehicle is stopped. They flash to grab attention and signal that something unusual is happening ahead or that you’re unable to move normally, such as when you’ve pulled over due to a breakdown or a temporary obstruction. They aren’t used for normal driving in clear weather, because that can confuse other drivers into thinking you’re stopping for a problem. They aren’t a substitute for turn signals, which are used to indicate lane changes or turns. And they aren’t a signal that you’re making a full stop on a highway; brake lights and controlled stopping are the proper signals in that situation, with hazard lights used to alert others if you’re stopped or dealing with a temporary hazard.
