Final answer:
When signaling to make a turn or lane change, it is important to signal every time you intend to make a turn or lane change.
Step-by-step explanation:
When signaling to make a turn or lane change, it is important to signal every time you intend to make a turn or lane change. This allows other drivers to anticipate your actions and adjust accordingly.
Signaling only while making the turn or lane change may not provide enough warning for other drivers, which can lead to accidents or confusion on the road.
Knowing that after signaling for 100 feet you have the right to make the turn or lane change is not accurate. The distance required for signaling may vary depending on local traffic laws and road conditions.
Therefore, the correct answer is option 2: Signal every time you intend to make a turn or lane change.
