Questions (8)
1. When changing lanes, you should:
- Move quickly, before other vehicles can enter into the lane.
- Move slowly in case another vehicle is in the lane. ✓
- Not use a turn signal.
- Avoid the right lane.
Answer: B. Move slowly in case another vehicle is in the lane.
You should move slowly and smoothly when changing lanes, in case another vehicle is in the lane. The handbook says to signal before changing lanes, then change lanes slowly and smoothly. It explains that this gives a driver you did not see a chance to honk or avoid your vehicle. That matches moving slowly in case another vehicle is already there. The goal is not to hurry across; it is to give yourself and others time to react.
2. 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.
3. Off-ramps:
- Are usually safest for trucks.
- Can be dangerous for trucks. ✓
- Should not be used by trucks.
Answer: B. Can be dangerous for trucks.
Off-ramps can be dangerous for trucks, so you need to slow down before you reach the curve. The handbook says freeway and turnpike exits can be particularly dangerous for commercial vehicles. Posted ramp speeds may be fine for cars but not for larger or heavily loaded vehicles, and an exit that drops downhill while it curves is especially risky because the downgrade makes it hard to slow down. Braking and turning at the same time is dangerous, so you should be going slowly enough before you get to the curved part of the ramp.
4. When making a lane change, your turn signal:
- Should always be used. ✓
- Should only be used if there is traffic present.
- Should only be used between dusk and dawn.
Answer: A. Should always be used.
Your turn signal should always be used when you make a lane change. The handbook says to use turn signals properly, activate them when required and at appropriate times, and cancel them after completing a turn or lane change. It also describes using the turn signal as part of moving into the lane you need. Nothing in these passages makes signaling a lane change depend on traffic being present or on the time of day, so the signal is treated as a normal part of the lane change itself.
5. Interstate carriers must have what information affixed to both sides of a CMV?
- USDOT number ✓
- Model number of the truck
- Destination
Answer: A. USDOT number
6. Laws about securing loads and regulating CMV weights may vary from state to state. During interstate travel:
- The law of the state in which the trip originated takes precedence.
- The law of the state the vehicle is in takes precedence. ✓
- The driver should request federal regulations to override conflicting state laws.
- The driver can choose which state’s laws to follow.
Answer: B. The law of the state the vehicle is in takes precedence.
7. 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.
8. When passing another vehicle, you should:
- Make eye contact with the other driver.
- Assume the other driver doesn’t see you. ✓
- Honk your horn.
- Wave to other drivers.
Answer: B. Assume the other driver doesn’t see you.
When passing another vehicle, you should assume the other driver does not see you. The handbook's communication section says other drivers may not notice your vehicle even when it is plainly visible. For passing, it gives a specific rule: whenever you are about to pass a vehicle, pedestrian, or bicyclist, assume they do not see you, because they could suddenly move in front of you. That is why you should expect the other driver to be unaware of you and drive carefully enough to avoid a crash, using a light horn tap or a night-time light flash only when it is legal.
