Questions (9)
1. When changing lanes, you should:
- Move quickly before other vehicles get into the lane you wish to occupy.
- Move slowly, in case another vehicle is in the lane you wish to occupy. ✓
- Not use your turn signal.
- Never use the right lane.
Answer: B. Move slowly, in case another vehicle is in the lane you wish to occupy.
When changing lanes, you should move slowly and smoothly in case another vehicle is already in the lane you want to occupy. The handbook says to put your turn signal on before changing lanes and then change lanes slowly and smoothly. It gives the reason directly: a driver you did not see may get a chance to honk or avoid your vehicle. That matches the choice about moving slowly because another vehicle may be in the lane. The passage does not set an exact speed for lane changes; it tells you to make the move gradual and controlled.
2. When entering traffic on an expressway during the skills test, you should:
- Check for traffic. ✓
- Not use signals.
- Abruptly enter a lane of traffic.
- Cut off other drivers if needed.
Answer: A. Check for traffic.
Check for traffic is the correct action when entering expressway traffic during the skills test. The handbook's on-road driving section expects regular traffic checks and a safe following distance. For lane changes, it says to make the needed traffic checks first, signal properly, and change lanes smoothly when safe. For expressway driving, it says to merge smoothly and to check traffic and mirrors thoroughly in all directions. When returning to the flow of traffic, it also says to check traffic from all directions, especially to the left, and to steer and accelerate smoothly when safe.
3. Simply changing lanes can cause:
- A “crack-the-whip” effect, resulting in a rollover. ✓
- A trailer to straighten out.
- Confusion over which lane the driver is hoping to use.
- Other drivers to reduce their speed.
Answer: A. A “crack-the-whip” effect, resulting in a rollover.
Simply changing lanes can cause a “crack-the-whip” effect that turns the trailer over. The combination vehicles section tells you to avoid quick lane changes, especially when loaded. It explains that trucks with trailers have a dangerous crack-the-whip effect, and a quick lane change can turn the trailer over. The doubles and triples section adds that these vehicles must be driven smoothly and that you should change lanes gradually to avoid rollover or jackknife. So the hazard tied directly to changing lanes is the trailer being whipped over, not a benefit or a vague social effect.
4. Once passing the CDL written test, an applicant must wait at least ____ before taking the skills tests.
- One hour
- One day
- Seven days
- 15 days ✓
Answer: D. 15 days
5. One way to overcome the challenges of blind spots is to:
- Drive faster than surrounding vehicles so no other drivers can pass you.
- Drive in the left lane, allowing you to only worry about vehicles to your right.
- Make frequent mirror checks and assess the positions of surrounding vehicles. ✓
- Avoid using your mirrors.
Answer: C. Make frequent mirror checks and assess the positions of surrounding vehicles.
Make frequent mirror checks and keep track of where surrounding vehicles are, so you know when one has slipped into a blind spot. The handbook says you cannot see everything with your mirrors, since blind spots exist that they do not show. That is exactly why it tells you to check your mirrors regularly: to know where other vehicles are around you and to notice when one moves into a blind spot. Checking often keeps you aware of traffic on both sides and behind, which matters if you suddenly need to change lanes.
6. Off-ramps:
- Are usually safe for trucks.
- Can be dangerous for trucks. ✓
- Should not be used by trucks.
- Should be used only if following another vehicle.
Answer: B. Can be dangerous for trucks.
Off-ramps can be dangerous for trucks. The handbook singles out freeway and turnpike exits as particularly risky for commercial vehicles. Posted ramp speeds may be fine for cars but not for larger or heavily loaded trucks. An exit that slopes down while it curves is especially hard because you must slow down and turn at the same time; braking and turning together is a dangerous practice. The combination-vehicle section adds that rollovers happen when you turn too fast and says to drive slowly around ramps and off-ramps. That supports treating off-ramps as hazardous, not as usually safe or off-limits.
7. When driving at highway speeds, you should watch the road about ____ ahead of your vehicle.
- One block
- 100 yards
- One quarter mile ✓
- One mile
Answer: C. One quarter mile
At highway speeds you should watch the road about one quarter mile ahead of your vehicle. The handbook says good drivers look at least 12 to 15 seconds ahead, which is the distance you 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 of a mile. Looking that far ahead gives you room to stop or change lanes without sudden moves, and the handbook notes that drivers who fall short of this may have to brake too hard or switch lanes too quickly.
8. When changing lanes:
- You should move your vehicle quickly.
- You should move your vehicle slowly. ✓
- The move should be made with a jerking motion.
- You do not need to use a turn signal.
Answer: B. You should move your vehicle slowly.
You should move your vehicle slowly when changing lanes. The handbook says to put your turn signal on before changing lanes, then change lanes slowly and smoothly. That slow, smooth move gives a driver you did not see a chance to honk or avoid you. Moving slowly is the answer that matches the handbook; the passage does not support quick movements or jerking the vehicle.
9. When asked to make a lane change during the skills test, you should:
- Make the necessary traffic checks first. ✓
- Not use your mirrors.
- Cut off other vehicles if needed to follow the instructions.
- Not make the lane change if you don’t want to.
Answer: A. Make the necessary traffic checks first.
You should make the necessary traffic checks first, then signal and change lanes smoothly when it is safe. The handbook's lane change section says that during the multiple lane portions of the skills test you will be asked to move left and then back right. For each of those changes, you first make the necessary traffic checks, then use proper signals, then move over smoothly when it is safe. So checking traffic comes before anything else, and the examiner is watching to see that order. The pass is not about obeying the instruction instantly; it is about doing the checks and signaling before you move.
