2. 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.
3. 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.
4. 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.
5. If stopped on the road or shoulder, within 10 minutes, you must:
Place emergency warning devices. ✓
Alert local law enforcement.
Stand behind your vehicle and motion for traffic to pass you.
Call a mechanic.
Answer: A. Place emergency warning devices.
If you stop on the road or shoulder, you must place your emergency warning devices within 10 minutes. The handbook says that when you pull off the road and stop, you should turn on your four-way emergency flashers. It also says that if you must stop on a road or the shoulder, you must put out your emergency warning devices within ten minutes, and it then gives placement distances for those devices. That makes placing the warning devices the required action inside that ten-minute window, so the answer is the choice about setting out emergency warning devices.
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.
Ramps connecting four-lane highways and two-lane highways.
Ramps that can be used by stop runaway vehicles on steep downhills. ✓
Ramps that cannot be used by automobiles.
Answer: C. Ramps that can be used by stop runaway vehicles on steep downhills.
Escape ramps are ramps built on steep downgrades to stop runaway vehicles safely. The handbook says escape ramps are built on many steep mountain downgrades. Their purpose is to bring a runaway vehicle to a stop without hurting the people inside, using a long bed of loose, soft material, sometimes combined with an uphill slope. It also tells drivers to know where the ramps are on their route because signs mark them, and to use one if the brakes fail going downhill. That matches the choice about stopping runaway vehicles on steep downhills.
