When driving on an interstate:
- Stop on the shoulder of the road if you are tired.
- You should always use cruise control.
- Signal, check mirrors, and check blind spots before changing lanes. ✓
- You should change lanes often.
Answer: C. Signal, check mirrors, and check blind spots before changing lanes.
Before changing lanes on an interstate, signal, check your mirrors, and check your blind spots.
Why this is the answer
The Florida handbook says that before you move to change lanes on a highway, you must turn your head to make sure the blind spots are clear. It defines blind spots as areas near the rear corners that your mirrors and peripheral vision do not cover. Another passage adds that you must activate your signal before moving into the left lane and check blind spots before pulling out. Together, these passages support signaling and looking carefully, including a head check, before a lane change.
Why the other answers are wrong
- A. Stop on the shoulder of the road if you are tired. — The passages do not say to stop on the shoulder when tired; they cover lane-change safety and blind spots, so this choice is not supported.
- B. You should always use cruise control. — No passage mentions cruise control or says you should always use it, so this choice adds a rule that is not in the handbook text provided.
- D. You should change lanes often. — The passages do not advise changing lanes often; they explain how to check and signal when you do change lanes.
Remember it
Think signal, mirror, then head check: look over your shoulder before you move over.
