When you change lanes, you should use your mirrors. The handbook treats lane changes as a special situation that calls for more than a quick glance. It says you need mirror checks to see whether someone is beside you or coming up to pass, and it lists checks before the move, after signaling, right after starting, and after finishing. It also describes using proper signals when changing lanes during the road test. Together, those points make mirror use part of a safe lane change, not something to skip.
3. If planning to change lanes, your mirrors should:
Not be checked.
Be checked as usual.
Be checked more often than usual. ✓
Answer: C. Be checked more often than usual.
When you plan to change lanes, check your mirrors more often than usual. The handbook treats lane changes as a special situation, and it says special situations call for more than your regular mirror checks. Before a lane change, you check to see whether someone is beside you or coming up to pass. After signaling, you check again for someone who may have slipped into your blind spot. You check right after starting the move and again after finishing it. That pattern of repeated looks is why the mirrors should get extra attention, not the same routine check.
4. During the driving test, when asked to make a lane change:
You should not be concerned with other motorists.
You should use your turn signal and change lanes when safe. ✓
You should make the lane change as quickly as possible, even if that means cutting off another driver.
Answer: B. You should use your turn signal and change lanes when safe.
You should use your turn signal and make the lane change only when it is safe to do so. The handbook's lane-change section says that during the driving test you first make the necessary traffic checks, then use proper signals, and then change lanes smoothly when it is safe. Section 2 adds that you must check your mirrors before changing lanes, after signaling, and again as you start, to be sure no one is alongside you or in your blind spot. Signaling and waiting for a safe gap are what the test is looking for.
A lane change should be done slowly and smoothly, not quickly or with a jerking motion. The handbook's lane-change rule says to signal first and then move over slowly and smoothly. It gives a practical reason: if another driver is in a spot you missed, a gradual move gives that person time to sound the horn or get out of the way. That is why the slow, smooth approach is the one the test expects.
Answer: B. Assume the other driver doesn't see you.
When passing another vehicle, assume the other driver does not see you. The handbook says that when you are about to pass a vehicle, pedestrian, or bicyclist, you should assume they do not see you, because they could suddenly move in front of you. It tells you to let them know you are there when it is legal, such as with a light horn tap or by flashing your lights at night, and to stay ready to avoid a crash whether or not they notice you. That supports assuming the other driver does not see you.
