CDL Practice Tests: Dominate The CDL Exam!
Choose A Section:
Go!If an oncoming driver has drifted into your lane, what is the best move?
- None of these are the best choice
- A move to your right
- A move to your left
- Stay straight. Do not veer out of your lane.
If you have an engine fire or a fire in the trailer:
- Do not open the hood or the cargo doors
- Disconnect the tractor from the trailer and move it away from the trailer
- Make sure you have a type 3 fire extinguisher
- Get into a service station as quickly as possible to put it out
With an engine fire, turn off the engine as soon as you can. Do not open the hood if you can avoid it. Shoot foam through louvers, radiator or from the vehicle’s underside.
For a cargo fire in a van or box trailer, keep the doors shut, especially if your cargo contains hazardous materials. Opening the van doors will supply the fire with oxygen and can cause it to burn very fast.
You may or may not be able to stop faster with ABS, but you should be able to:
- Steer around an obstacle while braking and avoid skids caused by over-braking.
- Keep the steer tires from veering too hard and thus avoiding a rollover
- Lock up the wheels, which creates more traction on the roadway
- Keep the air brake fluid primed for maximum braking force
Requirements for securing heavy vehicles, equipment, and machinery apply at what weight?
- More than 4,500 lbs
- More than 10,000 lbs
- Less than 10,000 lbs
- 50% the weight of the trailer
What Does This Section Cover?
The requirements in this section apply to the transportation of heavy vehicles, equipment, and machinery that:
- Operate on wheels or tracks, such as front end loaders, bulldozers, tractors, and power shovels.
- Individually weigh more than 4500 kg (10,000 lb.).
Timber used for dunnage must be all of the following except:
- All of these apply.
- Have grain should run lengthwise along the timber when it is used for structural purposes like blocking and bracing.
- Properly seasoned, and free of rot or decay.
- Free of knots, knotholes and splits that may affect its strength or interfere with nailing.
Timber used between tiedowns and cargo must be strong enough not to split or be crushed.
Any timber used should be properly seasoned, and free of rot or decay.
The grain should run lengthwise along the timber when it is used for structural purposes like blocking and bracing.
Timber should be free of knots, knotholes and splits that may affect its strength or interfere with nailing.
If you lose your brakes going down a steep grade, which of the following is true:
- If your foot brake fades to failure, use the trailer hand brake. This will normally still work in an emergency
- Use an escape ramp if it is available. If you do not use it, your chances of having a serious crash may be much greater.
- Steering gently back and forth will create additional friction which will slow the vehicle surprisingly fast, even without brakes.
- Do not use an escape ramp if at all possible. This is an outdated method of stopping. If you try to ride it out on the highway, your chances of surviving are better.
Brake Failure on Downgrades. Going slow enough and braking properly will almost always prevent brake failure on long downgrades. Once the brakes have failed, however, you are going to have to look outside your vehicle for something to stop it.
Your best hope is an escape ramp. If there is one, there will be signs telling you about it. Use it. Ramps are usually located a few miles from the top of the downgrade. Every year, hundreds of drivers avoid injury to themselves or damage to their vehicles by using escape ramps. Some escape ramps use soft gravel that resists the motion of the vehicle and brings it to a stop. Others turn uphill, using the hill to stop the vehicle and soft gravel to hold it in place.
Any driver who loses brakes going downhill should use an escape ramp if it is available. If you do not use it, your chances of having a serious crash may be much greater.
You operate on the 70-hour/8 day logbook schedule and you've used up all of your 70 hours. Which of the following can you legally do without any of your 70 hours available?
- Wait on-duty for the mechanics to service the vehicle
- Take an online safety course for your company
- Do a pre-trip inspection on the vehicle
- You can do all these
When calculating directional forces, 'g' is expressed as:
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.

What does the shipper use to warn drivers and dockworkers of the risk of hazardous materials?

To Communicate the Risk. The shipper uses a shipping paper and diamond-shaped hazard labels to warn dockworkers and drivers of the risk.
When doing an emergency system check on air brake systems, how do you begin the test?
- Turn electrical power off and begin fanning off the air pressure by rapidly applying and releasing the foot brake
- Turn electrical power on and begin fanning off the air pressure by rapidly applying and releasing the foot brake
- Turn off the electrical power and begin fanning off the air pressure by pulling out the red parking brake knob
- Turn the engine on and begin fanning off the air pressure by rapidly applying and releasing the foot brake

Tips For Passing the Commercial Driver's License (CDL) Permit Test
- Practice Makes Perfect: The best way to both mentally and physically prepare for the written exam is to take practice tests.

This will give you a good indication of how well you understand the material.
- Understand Instead of Memorize: Memorizing information can be helpful for the written exam, but the key to being fully prepared is to understand the material rather than just memorizing it. Understanding the material will allow you to answer questions correctly no matter how they are worded.
- Real World Applications: When struggling to understand concepts, create real-world scenarios to make the information more relevant to your life. Doing this will make it easier to remember come test time.
- Utilize Study Strategies: Utilizing study strategies such as flashcards, songs, rhymes, and phrases can help you remember the material.
- Be Fresh and Alert: The night before the exam, get a good night's sleep and eat a filling breakfast on the morning of the exam. This will ensure you are fresh and alert to take your exam.
- Begin Early and Space out Your Studying: It is important to give yourself ample time before the exam to get familiar with the material and get your mind ready for the big day. Consider taking a training course online or in-person, if it's required. Shop around for a course that works best for you. By following these tips, you will be well prepared for your written CDL exam and on your way to a successful career.
