Passing Score 40

1. When driving through a curve during the skills test, you should:

Veer from your lane if needed to complete the curve.

Reduce your speed after entering the curve.

Refrain from looking for other vehicles while turning.

Reduce your speed before entering the curve.

When approaching a curve during the on-road driving skills test, you must reduce your speed sufficiently before entering the curve so that you do not need to further brake or shift in the curve. Keep the vehicle in its lane and continue to check for traffic in all directions.

2. When you need to brake, how can you warn drivers behind you?

Tap on the brakes a couple of times.

Stick your arm out the window.

Swerve within your lane.

Change lanes.

To warn drivers behind you that you are about to slow down, it may be a good idea to first lightly tap your brake pedal a few times to make the brake lights flash.

3. Regrooved tires:

Should not be used on any vehicle.

Should not be used on the front of a bus.

Should not be used on trucks hauling gravel.

Regrooved, recapped, or retreaded tires are prohibited on the front wheels of a bus.

4. If your brakes fail on a downgrade, your best hope to stop is:

An escape ramp.

Driving on the shoulder.

Stay on the road.

Hitting a slower vehicle in front of you.

If your brakes fail on a downgrade, your best option is to use an escape ramp. If no escape ramp is available, it is a good idea to look for a different escape route, such as a side road or open field.

5. When operating a vehicle with a dual air brake system, the driver should:

Let the vehicle warm up before driving to ensure that the fuel reaches the engine.

Let the air compressor build up a minimum of 100 psi pressure in the primary and secondary systems before driving.

Begin driving just after the vehicle starts.

Before driving a vehicle with a dual air brake system, allow time for the air compressor to build up a minimum of 100 psi pressure in both the primary and secondary systems. Watch the air pressure gauges to monitor the pressure levels.

6. If driving so slowly that you could impede other drivers, you should:

Drive in the left lane.

Drive while using your four-way flashers.

Drive without using any lights.

If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).
