Explanation: Using your turn signals

In order to pass your DMV exams and to become a safe driver, it’s important to know the reason why a particular answer on the written test is correct. 

Your turn signals (or hand signals) are one of the most common ways you’ll communicate with other drivers, bicycles, and pedestrians on the road. 

It is important that you signal early enough so that other drivers know what you are going to do and can react accordingly. 

At lower speeds (under 45 mph), you should use your turn signals at least 100 feet before you need to make your turn or change lanes. 

At higher speeds (above 45 mph), you should use your turn signals for at least 200 feet before you turn or change lanes. 

These distances give other drivers enough time to recognize your intentions so they can either slow down, stop, or change lanes as necessary. 

Communicating your intentions with other drivers reduces the risk of a crash and helps traffic flow more smoothly.

You can find more information about this topic in the communicating with other drivers section of your driver’s handbook.
