- Driver-assist Crossing
- Active Crossing
- Passive Crossing
- Yield-only Crossing
Passive Crossings. This type of crossing does not have any type of traffic control device. The decision to stop or proceed rests entirely in your hands. Passive crossings require you to recognize the crossing, search for any train using the tracks and decide if there is sufficient clear space to cross safely. Passive crossings have yellow circular advance warning signs, pavement markings, and crossbucks to assist you in recognizing a crossing.
Active Crossings. This type of crossing has a traffic control device installed at the crossing to regulate traffic at the crossing. These active devices include flashing red lights with or without bells and flashing red lights with bells and gates.
Which of the following is true about having ABS on only the tractor, only on the trailer, or only on one axle?
- Having ABS on only the tractor, only the trailer, or even on only one axle still gives you more control over the vehicle during braking, but greatly increases your chances of jackknifing on slick roads if you don't use stab braking
- Having ABS on only the tractor, only the trailer, or even on only one axle does almost no good whatsoever. You should brake as if you do not have ABS at all.
- Having ABS on only the tractor, only the trailer, or even on only one axle gives you less control over the vehicle during braking than without any ABS at all. Brake more cautiously than without ABS.
- Having ABS on only the tractor, only the trailer, or even on only one axle still gives you more control over the vehicle during braking. Brake normally.

At the crossing:
- Stop no closer than 15 feet and no farther than 50 feet from the nearest rail, where you have the best view of the tracks.
- Place the transmission in “Park” (if there is no “Park” shift point, use “Neutral”) and set the parking brake.

The tractor parking valve will close automatically if air pressure is in what range?
- 40 to 60 psi

Specific cargo securement rules on automobiles and light trucks apply to vehicles of what weight?
- 4,500 lbs or less
- 10,000 lbs or less
- It depends on what the vehicle is used for.
- 12,000 lbs or less
What Does This Section Cover?
The requirements in this section apply to the transportation of automobiles, light trucks, and vans that individually weigh 4500 kg (10,000 lb.) or less.
Based on the following figures, how much fuel can you legally add while remaining legal on the steer axle?
Percentage of fuel weight to steer axle: 85%
Steer axle weight limit in states you're travelling: 20,000 pounds
Weight Before Fueling: Steer: 11,500, drives: 33,100, gross: 76,700
- 117.64 gallons of fuel
- 129.5 gallons of fuel
- 133 gallons of fuel
- 110.75 gallons of fuel
Because we know that 85% of the weight of fuel will go to the steer axle and you can add 850 pounds to your steer axle, we can plug the numbers into the formula above.
800/85 = 9.41
9.41 x 100 = 941
941/8 = 117.63 gallons of fuel you can add
In terms of cargo securement, what is a 'well'?
- A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
- A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
When you double your speed from 20 to 40 mph, the impact on "total stopping distance" and "braking distance" is:
- The impact is barely noticeable
- Eight times greater
- Four times greater
- Two times greater
The Effect of Speed on Stopping Distance. The faster you drive, the greater the impact or striking power of your vehicle. When you double your speed from 20 to 40 mph, the impact is four times greater. The braking distance is also four times longer.

CDL Practice Tests
Our CDL practice tests are designed to help test your knowledge of the CDL Manual and sharpen your skills for taking the CDL permit and endorsement exams. They are not designed to teach you the knowledge necessary to pass the exams. Please do not try to memorize CDL practice tests in order to get your CDL. There's a better way.
Our High Road CDL Training Program is by far the easiest and most effective way to learn the materials necessary for passing your written CDL exams and preparing for a great start to your career.

How to Pass CDL Permit Test the First Time
The Class A CDL permit exam consists of a multiple choice test covering 20 different areas related to commercial driving. To prepare for this test, it is important to do practice tests beforehand. Knowing your personal study habits, getting enough rest, and eating a healthy breakfast will also set you up for success.
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. Start out with open-book tests and gradually work your way up to giving yourself a time limit. Finally, before the big day, take a practice exam as if it were the real thing without any help. 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.
