Delaware CDL: Passenger Vehicles Practice Test

Not quite. The answer is 50 feet

At drawbridges without a traffic attendant or light signal, you must stop at least 50 feet before the draw of the bridge. If there is a green light or a traffic attendant present, you don't have to stop, but you must slow down and make sure that the drawbridge is closed and safe to drive on before you proceed across it.

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 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 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 Both of the above are true.

Don't tow a disabled bus with passengers aboard unless it would be unsafe to discharge them first. In that case, tow or push the bus to the nearest safe location to discharge the passengers.

Not quite. The answer is wait for a sufficient gap in traffic.

Know how big a gap in traffic your bus needs to merge into traffic. Before you can pull out of a bus stop, you must wait for a large enough gap in traffic. Never assume that other drivers will brake to let you into traffic.

Not quite. The answer is 50 feet

Stop at drawbridges that do not have a signal light or traffic control attendant. Stop at least 50 feet before the draw of the bridge and look to make sure the draw is completely closed before you proceed across.

Not quite. The answer is No, because it may distract the bus driver from driving.

Conversations with passengers represent a distraction from the driving task. The bus driver should avoid all potential distractions while driving the bus. The only real way to treat feelings of sleepiness is with sleep.

Not quite. The answer is before the trip.

Many charter and intercity carriers have passenger comfort and safety rules. At the start of the trip, tell the passengers about the rules on smoking, drinking, or using personal electronic devices. Explaining the rules at the start will help avoid trouble later on. While driving, keep an eye on the passengers. Remind them if you see them breaking the rules.

Not quite. The answer is 100 pounds of any one class of allowed hazardous materials.

Passenger buses can carry up to 100 pounds of each class of hazardous materials and up to 500 pounds total. However, there are some exceptions. Division 2.3 (poison gases) and liquid Class 6 (poisons) cannot be carried in any amounts. Class 1 (explosives) and Class 7 (labeled radioactives) cannot be carried in the passenger area.

Not quite. The answer is all of the above.

Relatively small amounts of hazardous materials that are packaged to reduce risk may be classified as a “Limited Quantity (LQ).” Examples include aerosol cans and chemicals (such as bleaches) that are intended to be sold retail to consumers. LQ materials are exempt from the usual shipping paper requirements for hazmat. Also, a vehicle transporting only LQ packages does not have to be placarded. The maximum allowed amounts and the federal packaging requirements for LQ depend on the hazard class of the material. The outer packaging of each LQ package must bear the diamond-shaped Limited Quantity mark. This mark replaces the older “Other Regulated Materials – Domestic (ORM-D)” designation, which was phased out by December 31, 2020. Unlike ORM-D, Limited Quantity packages may be shipped internationally, subject to United Nations (UN) and other international requirements.

Not quite. The answer is flash your brake lights to let the drivers behind you know that you are stopping.

You may have to stop on the roadway to load or unload passengers. In such situations, warn following drivers by flashing your brake lights. Do not stop suddenly.

Not quite. The answer is in a closed building with passengers on board.

Avoid fueling your bus with riders on board unless it is absolutely necessary. Never refuel in a closed building with riders on board.

Not quite. The answer is it must be secured while the bus is being driven.

Emergency exit doors and windows must be securely closed whenever the bus is moving. Signage must be visible. If there is a red emergency door light above the emergency exit, it must work properly and be turned on whenever you use your headlights.

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 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 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 You need about four times as much braking distance at 40 mph as at 20 mph.

When you increase your speed, your braking distance increases as the square of the speed increase. If you double your speed, your braking distance will be four times as great.

Not quite. The answer is 500 pounds

Buses may carry small amounts of certain hazardous materials, such as small-arms ammunition labeled "Limited Quantity," emergency hospital supplies, and drugs. Buses may not carry more than 100 pounds of any hazard class or more than 500 pounds total.

Not quite. The answer is watch for poles and tree branches.

School and mass transit buses sometimes scrape off mirrors or hit passing vehicles when pulling out from a bus stop. Remember the clearance your bus needs, and watch for poles and tree limbs at stops. Know the size of the gap your bus needs to accelerate and merge with traffic. Wait for the gap to open before you leave the stop. Never assume that other drivers will brake to leave you room when you signal or start to pull out.
