Questions (3)
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.
