Florida Class E Drivers License Practice Test

The correct arm signal for a left turn is to extend your left arm straight out. This is because it is universally recognized as the standard signal for a left turn, allowing other drivers and cyclists to easily understand your intention. Option B, putting the left arm and hand up at a 90-degree angle, is the standard arm signal for a right turn. Option C, pointing the right arm outward, is not a recognized arm signal for any turn. Option D, extending both arms out straight, is typically used as a signal for stopping or slowing down, not for indicating a turn. Therefore, option A is the correct and most effective arm signal for a left turn.
