Questions (4)

1. During the driving test, when asked to make a lane change:
  1. You should not be concerned with other motorists.
  2. You should use your turn signal and change lanes when safe. ✓
  3. 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.
2. When changing lanes:
  1. You should not use your mirrors.
  2. You should use your mirrors. ✓
  3. You should not use your turn signals.

Answer: B. You should use your mirrors.

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. Escape ramps are ramps that can be used:
  1. Only by automobiles, not trucks.
  2. To leave the highway and enter a two-lane highway.
  3. To stop runaway vehicles on steep downhills. ✓

Answer: C. To stop runaway vehicles on steep downhills.

Escape ramps are built to stop runaway vehicles on steep downgrades. The handbook says escape ramps have been built on many steep mountain downgrades to stop runaway vehicles safely without injuring drivers and passengers. It explains that they use a long bed of loose, soft material, sometimes with an upgrade, to slow a runaway vehicle. It also tells drivers who lose brakes going downhill to use an escape ramp if one is available, and warns that not using it can make a serious crash much more likely.
4. When driving at highway speeds, you should watch the road about ____ ahead of your vehicle.
  1. One block
  2. 100 yards
  3. A quarter mile ✓

Answer: C. A quarter mile

At highway speeds you should watch the road about a quarter mile ahead of your vehicle. The handbook explains that good drivers look 12 to 15 seconds ahead, which is the distance the vehicle will cover in that time. At lower speeds that works out to roughly one block, and at highway speeds it comes to about a quarter mile. Looking that far ahead matters because stopping and lane changes take a lot of distance, so you need to see traffic early enough to have room to make those moves safely. Close attention still counts; good drivers shift their eyes between near and far.
