Explanation
Before making any turn, whether you are turning at an intersection, changing lanes, pulling away from a curb or pulling off to the side of the road, it is very important that you signal your intention to other drivers. Your signal helps other drivers plan ahead. On the other hand, a surprise move may result in an accident. In Tennesse, drivers are required to use their turn signal at least 50 feet before the turn or lane change.
