Iowa CDL: Passenger Vehicles Practice Test

Not quite. The answer is At the end of your shift

If you work for an interstate carrier, you must complete a post-trip vehicle inspection report for each vehicle you drove during your shift. Note any safety-related problems that you found while driving the vehicle and repairs that you believe are needed. The inspection report will let the next driver know if there are safety-related problems. It will also let the carrier know if safety-related repairs are needed. Federal regulations require an inspection report be completed by the end of the day's use of the vehicle. Effective September 2020, federal regulations no longer require you to submit an inspection report if you found no defects in the vehicle and know of no defects in the vehicle.

Not quite. The answer is 16

To drive a vehicle with 16 or more occupants including yourself, you must have a CDL with a Passenger (P) endorsement.

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 small-arms ammunition

Passenger buses can carry up to 100 pounds of certain hazardous materials, such as small-arms ammunition labeled "Limited Quantity," emergency hospital supplies, and drugs. 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 in front of the standee line.

No rider may stand forward of the rear of the driver’s seat. Buses designed to allow standing must have a two-inch line on the floor or some other means of showing riders where they cannot stand. This is called the standee line. All standing riders must stay behind it.

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 all of the above have been checked.

Before driving your passenger vehicle, you must also inspect the interior to ensure passenger safety. Make sure that the aisles and stairwells are clear, all emergency exits are closed and secured, all signaling devices are in working order, and the handles, handholds, and railings are securely fastened.

Not quite. The answer is check expressway traffic, signal, and merge smoothly into traffic.

To enter an expressway, perform the following steps: 1. Check for traffic. 2. Use the proper signals. 3. Merge smoothly into the proper lane of traffic.

Not quite. The answer is scan the interior of your bus and the road all around it.

Many charter and intercity carriers have passenger comfort and safety rules. While driving, scan the interior of your bus as well as the road ahead, to the sides, and to the rear. You may have to remind riders about the rules, or remind them to keep their arms and heads inside the bus.

Not quite. The answer is only when the bus is stopped.

Once you start to drive, give your driving your undivided attention. Adjust your mirrors, seat, radio, etc., before you start driving or when the bus is stopped.

Not quite. The answer is slow down.

When switching from high-beam lights to low beams, slow down, since you will not be able to see as far in front of you.

Not quite. The answer is Never

Never drive with an open emergency exit door or window. Keep it closed for your passengers' safety.

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 Your stopping distance quadruples if you double your speed.

You need about four times as much stopping distance when travelling at 40 mph compared to 20 mph.

Not quite. The answer is Allow much more space than is needed under ideal driving conditions.

The usual formula for following distance under ideal conditions is one second for every ten feet of vehicle length, plus an extra second if you are traveling at over 40 mph. The only thing the CDL manual says about following distance on slippery roads is that you should allow "much more space to stop." The Federal Motor Carrier Safety Administration (FMCSA) recommends doubling your usual following distance under poor driving conditions.

Not quite. The answer is the AM/FM radio.

Before you start to drive, you must check all the critical systems such as steering, brakes, tires, and emergency equipment to be sure they work properly. For the passengers' safety, you must also check such interior items as seats, handholds, railings, signaling devices, and emergency exits. FM or DVD music is nice, but you can safely drive your passengers to their destinations without it.

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 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 on any wheels except the front wheels.

Federal regulations prohibit the use of recapped, regrooved, or retreaded tires on the front wheels. A tire failure on the steering axle is more likely to result in loss of control than a tire failure elsewhere.

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.
