Florida Turn Signaling Law
Signaling Turns (see Sub-section 316.155(2) and 316.157(2), F.S.)
* A signal of intention to turn must be given during the last 100 feet traveled by the vehicle before turning. If a bicyclist needs both hands for control, the signal need not be given continuously.
* A bicyclist may signal intent to turn right either by extending the left hand and arm upward or by extending the right hand and arm horizontally to the right side of the bicycle.
