Final answer:
To let others know you intend to turn, give signals at least 100 feet from the place you plan to turn.
Step-by-step explanation:
To let others know you intend to turn, give signals at least 100 feet from the place you plan to turn. This will provide enough time for other drivers to react and adjust their own driving accordingly. For example, if you are approaching an intersection and want to turn right, activate your right turn signal at least 100 feet before the intersection.
