Signaling your intentions before turning, changing lanes, or driving away from a curb:
- Is necessary only if other traffic is present.
- Is a good driving habit and is required by law. ✓
- Is necessary only during the maneuver, not before.
- Is not necessary if the maneuver is done slowly.
Answer: B. Is a good driving habit and is required by law.
Signaling before turning, changing lanes, or driving away from a curb is a good driving habit and is required by law.
Why this is the answer
Florida's handbook treats signaling as both a habit and a legal duty. It says you must use directional or hand signals to show others you are turning, and that turn signals are required by law when you change lanes or overtake. It also says to signal at least 100 feet before a turn. For leaving a curb, the handbook says to give the proper turn signal and yield before pulling away. None of this depends on whether traffic is present, how fast you move, or signaling only during the maneuver.
Why the other answers are wrong
- A. Is necessary only if other traffic is present. — The passages set signaling as a legal requirement and do not make it depend on whether other traffic is present.
- C. Is necessary only during the maneuver, not before. — The handbook says to signal at least 100 feet before a turn and before pulling away from a curb, so signaling only during the maneuver is too late.
- D. Is not necessary if the maneuver is done slowly. — Nothing in the passages excuses signaling because a maneuver is slow; the signal is required by law.
Remember it
Think ahead: signal before you move, not while you move, so others can predict your action.
