Always signal when:
- Changing lanes.
- Pulling into or out of a parking space.
- Pulling into traffic from an alley or parking area.
- All of the above. ✓
Answer: D. All of the above.
All of the above — you signal when changing lanes, when pulling into or out of a parking space, and when pulling into traffic from an alley or parking area.
Why this is the answer
The Texas handbook says a good driver lets others know before turning or stopping, and it warns that a surprise move often leads to a crash. Its list of times to always signal includes changing lanes, pulling away from a parking space at the curb, and entering or leaving a highway. Each situation in the question is a move where drivers around you need warning, so all of them call for a signal. Picking just one would leave you unsignaled in the others.
Why the other answers are wrong
- A. Changing lanes. — Changing lanes is on the handbook's signal list, but it is only one item, so treating it as the whole answer leaves out the other moves that also require a signal.
- B. Pulling into or out of a parking space. — Pulling into or out of a parking space is covered by the handbook's rule about signaling when you pull away from a parking space at the curb, but it is just one of several situations listed.
- C. Pulling into traffic from an alley or parking area. — Pulling into traffic from an alley or parking area is another move where other drivers need warning, but naming only this one leaves out lane changes and parking-space moves.
Remember it
Ask yourself one question before you move: will the driver behind me be surprised? If yes, signal first.
