Always signal when:
- Changing lanes.
- Pulling into or out of a parking space.
- Pulling into traffic from a parking area or alley.
- All of the above. ✓
Answer: D. All of the above.
The answer is all of the above: you should signal for changing lanes, for pulling into or out of a parking space, and for pulling into traffic from a parking area or alley.
Why this is the answer
The handbook's signaling chapter says a good driver always lets others know what he or she is about to do, because a surprise move often leads to a crash. It then gives a list of moves that always call for a signal, and changing lanes and pulling away from a parking space are both on that list. The same reasoning covers entering or leaving a roadway or traffic flow. The passage does not spell out every one of these situations word for word, but the list is presented as the basic set of times a signal is required.
Why the other answers are wrong
- A. Changing lanes. — Changing lanes is one of the listed times to signal, but the handbook's list does not stop there, so this choice is only part of the rule.
- B. Pulling into or out of a parking space. — Pulling into or out of a parking space is also a signal situation, but naming only that one leaves out the other moves the handbook lists.
- C. Pulling into traffic from a parking area or alley. — Pulling into traffic from a parking area or alley is another case where you signal, yet it is not the whole answer by itself.
Remember it
Think of a signal as a message you owe other drivers any time your car is about to move somewhere they would not predict.
