What does Florida law require drivers to do to indicate lane changes?

Florida law mandates that drivers must use turn signals to indicate lane changes. This requirement is in place to promote safety on the roads by ensuring that other drivers are aware of a vehicle's intention to change lanes. By using turn signals, drivers provide a visual cue, which helps prevent accidents caused by sudden movements or misunderstandings between vehicles on the road. Proper signaling is a fundamental part of safe driving practices, as it supports clear communication among drivers, ultimately enhancing traffic flow and reducing the risk of collisions.

The other methods, such as using horn signals, turning on headlights, or flashing hazard lights, are not standard or legally required ways to indicate lane changes and serve different purposes in driving. Horn signals are typically used to alert other drivers or pedestrians, headlights are primarily for visibility, and hazard lights indicate an emergency situation rather than a change in direction.
