Idaho CDL: Passenger Vehicles Practice Test

Not quite. The answer is regularly as part of your scan for potential hazards.

While driving, scan the interior of your bus as well as the road ahead, to the sides, and to the rear. Check your mirrors regularly. You need to make regular checks of your mirrors to be aware of traffic and to keep an eye on your vehicle. Check more often in special situations.

Not quite. The answer is Yes, but only up to 100 pounds.

Many hazardous materials cannot be carried on a bus. These include any amounts of Division 2.3 poison gases, liquid Class 6 poisons, or tear gas; or more than 100 pounds of solid Class 6 poisons. Also, buses may never carry explosives (except small-arms ammunition) or radioactive materials in the space occupied by people. Finally, buses may not carry more than a total of 500 pounds of allowed hazardous materials, and no more than 100 pounds of any one class.

Not quite. The answer is properly labeled.

The rules require shippers to mark containers of hazardous materials with the material’s name, identification number, and a hazard label.

Not quite. The answer is slow down and make sure it's safe to proceed.

You don't have to stop at a drawbridge if you have a green light or there is an attendant or traffic officer present. However, you should still slow down and make sure that the drawbridge is closed and safe to drive on before you proceed across it. The Rio Vista Bridge shown in the image is a vertical-lift bridge that crosses the Sacramento River along California State Route 12.

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 While crossing, don't shift gears if your bus has a manual transmission.

You must stop at every railroad crossing except those marked "exempt" or "abandoned." 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 at intersections.

Bus accidents often happen at intersections, where there are many drivers and pedestrians doing different things. Use caution at intersections even if there are signs or signals that are supposed to control traffic. Also use caution at railroad crossings. Buses are required to stop at railroad crossings.

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 the defects listed on it have been certified as either repaired or not needing to be repaired.

Don't sign a previous driver's inspection report unless the defects listed on it have been certified as either repaired or not needing to be repaired. You will, of course, perform your own pre-trip inspection.

Not quite. The answer is A spare jacket

Federal regulations require CMVs to carry emergency warning devices, such as reflective triangles, and a properly rated fire extinguisher. A spare jacket may be useful in cold weather, but it is not federally required emergency equipment. Spare electrical fuses are also no longer federally required under current FMCSA regulations.

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 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 small-arms ammunition.

Buses may carry small-arms ammunition marked "Limited Quantity" (relatively small quantity of hazmat; formerly "ORM-D"), emergency hospital supplies, and drugs. Buses may carry small amounts of some other hazardous materials if the shipper cannot send them any other way. Buses may not carry more than 100 pounds of any class or more than 500 pounds total.

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 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 Any defects that could affect safety or result in a breakdown

At the end of each shift, inspect each bus that you drove. If you find any defects, you must complete a written inspection report and submit it to the carrier. Your report must specify each bus and list any defects that could affect safety or result in a breakdown. Note: Effective January 19, 2022, you are no longer required to complete an inspection report for a bus if you don't find or know about any defects.

Not quite. The answer is not allow the rider to do it.

Buses are allowed to carry small amounts (up to a total of 500 pounds) of certain hazardous materials. But not battery acid or gasoline.

Not quite. The answer is 50 feet

When you approach a drawbridge without a signal light or traffic control attendant, you must stop at least 50 feet before the draw of the bridge to make sure that the drawbridge is closed and safe to cross.

Not quite. The answer is It depends on the state.

There is no national requirement for coach buses to stop at permanent weigh station locations. Instead, each state can set its own rules. As of March 2021, there are 24 states in which coach buses must stop at weigh stations, at least under certain circumstances.

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.
