Florida law requires that drivers of vehicles not turn right or left without using a turn signal at least 100 feet before taking a turn. Failing to signal correctly can result in a noncriminal moving violation for a driver, which requires the driver to appear before a judge. Florida Statute § 316.155 defines legal requirements for turn signals. The statute provides five rules: No person can turn a motor vehicle from a direct course or move right or left upon a highway unless and until their movement can be performed with reasonable safety, and even then, only after they give an appropriate signal, in the event any other motor vehicle could be affected by the movement. A signal of driver intention to turn right or left has to be given continuously during not less than the final 100 feet traveled by a motor vehicle before turning, except that a signal by hand or arm need does not need to be given continuously by a bicyclist if their hand is necessary for the control or operation of the bicycle. No person can stop or suddenly decrease the speed of a motor vehicle without first giving an appropriate signal to any driver of a motor vehicle immediately to the rear when there is an opportunity to give such a signal. The signals provided for in Florida Statute § 316.156, relating to signals by hand and arm or signal lamps, should be used to indicate an intention to turn, overtake, or pass a vehicle and cannot, except as provided in Florida Statute § 316.2397, relating to certain lights prohibited and exceptions, be flashed on only one side on a parked or disabled vehicle, flashed as a courtesy, or a so-called “do pass” signal to operators of other motor vehicles approaching from the rear. A violation of Florida Statute § 316.155 is a noncriminal traffic infraction, punishable as a moving violation as provided in Chapter 318. The Florida Department of Motor Vehicles offers further guidelines for making safe turns, including: Don’t make last-second turns decide early where you are going and when you need to turn. Move into the correct lane as soon as possible when you near the turn. Slow to a safe speed for making the turn. Look over your shoulder for bicyclists or pedestrians before completing a turn. Continue driving if you cannot safely make your turn due to vehicles blocking the intersection or other obstacles. Finish your turn in the correct lane if you turn right, go into the right lane; if you go left, go into the left lane. Never make a right turn from a left lane. Never make a left turn from a right lane. Never block traffic to turn if the turn lane is too full. If a driver cannot safely turn, they should continue driving until they can make a safe turn. Sometimes, however, drivers decide to make the turn immediately, even if it means they have to act unsafely. When drivers act in this manner, they can endanger others.
