Minnesota CDL: Passenger Vehicles Practice Test

Not quite. The answer is safe for cars in good weather.

Each curve has a safe "design speed," which is its safe speed for cars in good weather. However, at that speed, a bus is more prone to rolling over. And it may not be safe for any vehicles to travel at that speed in bad weather. In particular, a bus could go sliding right off the road. For safety on curves, slow down below the posted speed. If your bus is leaning outward on a banked curve, you are driving too fast.

Not quite. The answer is so any door or window can be used in an emergency.

Carry-on baggage must not be left in a doorway or aisle where it could trip riders. Secure baggage and freight so it (a) remains undamaged; (b) allows the driver to move freely and easily; (c) allows riders to exit by any window or door in an emergency; and (d) protects riders from injury if carry-on baggage falls or shifts.

Not quite. The answer is All of the above requirements must be met.

Carry-on baggage must not be left in doorways or aisles because someone could trip over it or it could block the way to an emergency exit. Carry-on luggage must be stowed so it can't restrict the driver's movements or injure passengers if it falls or shifts.

Not quite. The answer is close any open access panels.

As you check the outside of the bus, close any open emergency exits. Also, close any open access panels (for baggage, restroom service, engine, etc.) before driving.

Not quite. The answer is You must be able to stop within the distance that you can see ahead.

You should know the safe driving speeds for your vehicle under both ideal driving conditions and poor driving conditions. The posted speed limits on curves are safe for cars under ideal driving conditions, but not necessarily safe for large vehicles like buses. On a curve, you may have to slow down below the posted speed.

Not quite. The answer is Slow to a safe speed before entering the curve, then accelerate slightly through it.

The safest way to take a curve is to slow down before the curve and then accelerate slightly through the curve. Braking in a curve risks a skid.

Not quite. The answer is Shift your attention back and forth, near and far.

While driving your vehicle, look ahead a full 12–15 seconds. Be aware of what is happening all around your vehicle, both farther from it and closer to it. Keep shifting your attention back and forth, near and far, left and right, so that you can constantly scan all these areas.

Not quite. The answer is Never

During your pre-trip inspection, make sure that the emergency exit doors and windows are closed. Never drive with them open. However, you are allowed to lock some emergency roof hatches in a partly open position for fresh air. Keep in mind that doing so adds to the height of the bus.

Not quite. The answer is not shift gears

If your bus has a manual transmission, do not shift gears while crossing a raised railroad crossing. Shifting gears on a raised railroad crossing increases the chance that your vehicle will stall and get stuck on the tracks.

Not quite. The answer is All of the above

If the coach bus has a restroom (lavatory), check the following during your pre-trip inspection of the vehicle: (1) The restroom must be clean overall. (2) The Vacant/Occupied indicator must be present, clean, undamaged, and working properly. (3) The restroom lights must work properly when the restroom door is closed. (4) The restroom must be properly stocked with enough soap and toilet paper for the trip, and (these days) hand sanitizer as well.

Not quite. The answer is Fire extinguisher and warning devices for stopped vehicles

Federal regulations require every commercial motor vehicle (CMV) to carry one of the following warning devices in case the driver must stop the CMV on the road: three reflective triangles or six fusees. Federal regulations also require every CMV to carry a fire extinguisher. Your state may also require extra emergency equipment, such as a first-aid kit, on certain vehicles.

Not quite. The answer is 5 seconds

The formula for following distance is one second for every ten feet of vehicle length, plus an extra second if you are traveling over 40 mph. Therefore, for a 40-foot vehicle traveling at 50 mph, you should leave a following distance of 40/10 + 1 = 5 seconds.

Not quite. The answer is All of the above

When changing lanes, check your mirrors at each of the following times: (1) before you change lanes, to make sure there is enough room; (2) after you have signaled, to check that no one has moved into your blind spot; (3) right after you start the lane change, to double-check that your path is clear; and (4) after you complete the lane change.

Not quite. The answer is only if getting off the bus would be more risky for the riders.

Passengers should not be aboard a bus while it is being towed unless it would be more dangerous for them to exit the vehicle. Passengers can remain aboard the bus only until it is towed or pushed to the nearest safe location.

Not quite. The answer is The emergency window

Emergency exit windows and doors must be closed while the bus is being driven.

Not quite. The answer is may be locked in a partially open position.

You may lock roof hatches into a partially open position to provide fresh air. However, don't leave them open all the time. When open, they add to the bus's height, which can pose problems when driving through an underpass with low vertical clearance.

Not quite. The answer is Before you bring the bus to a complete stop

Before you come to a complete stop, remind riders who are getting off the bus to take their belongings with them. If the aisle is on a lower level than the seats, also remind riders of the step-down.

Not quite. The answer is No.

Never drive with an open emergency exit door or window. As part of your pre-trip inspection of the interior of the bus, check that all emergency exit doors and windows are securely closed.

Not quite. The answer is You should avoid traveling alongside other vehicles whenever possible.

Whenever another vehicle is traveling alongside yours, there's always a chance that the vehicle might try to move into your lane and accidentally hit your vehicle. Also, the vehicle is blocking you from changing lanes. It's safer to find an open spot where there are no vehicles on either side of you. (Of course, that may not be possible in heavy, congested traffic.)

Not quite. The answer is All of the above

The North American Standard Out-of-Service Criteria includes the following critical inspection items for passenger vehicles, such as buses and passenger vans: (1) All required emergency exits must be present, fully operative, and unobstructed. (2) No passenger seats may be loose. (3) There must be no bare cables exposed in the battery compartment or engine compartment. (In this context, a cable is the power-conveying part of a high-wattage or high-voltage electrical system.) If any of these critical criteria are not met, your bus can be put out of service.
