36. Regrooved tires are:
Explanation
Regrooved, recapped, or retreaded tires are not permitted to be used on the front of a bus.
37. Talking on a hands-free phone while driving:
Explanation
While speaking on a hands-free phone while driving is less dangerous than speaking on a hand-held phone, it is just as likely to mentally distract a driver. Simply engaging in conversation takes their mental focus away from the task of driving.
38. Hydroplaning happens most often when:
Explanation
Hydroplaning is most likely to occur when driving on wet roads with tire pressure that is too low and tire tread that is too worn. If there is enough water on the road, hydroplaning can occur at speeds as low as 30 mph.
39. Which of the following could reduce the amount of space between the road surface and an overhead object, such as a bridge?
Explanation
You should not assume that signs marking the height of a bridge or overpass are exactly correct. If the road was repaved after the sign went up, or if snow is on the ground, the clearance may be different than what the sign indicates.
40. If driving so slowly that you could impede other drivers, you should:
Explanation
If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).
41. Exercise will help a person sober up after drinking.
Explanation
The liver removes alcohol from the body at a fixed rate. Despite popular belief, tricks like exercising or taking a cold shower will not speed up this process. The only way to become sober after drinking is to allow the body the time it needs to get rid of the alcohol.
42. When taking the on-road driving test, you will be evaluated on your lane usage. Which of the following is an example of poor lane usage?
Explanation
During the on-road driving skills test, make sure you do not put your vehicle over curbs, sidewalks, or lane markings. Stop behind stop lines, crosswalks, or stop signs. On multiple-lane roads, complete turns in the proper lane. Always move to or remain in the rightmost lane, unless the lane is blocked.

The Class B CDL skills test is divided into three parts: pre-trip inspection, basic vehicle control, and on-road driving.
1. Pre-trip inspection: You will be required to inspect the vehicle and identify any potential problems or safety hazards. This includes checking the engine, brakes, lights, tires, steering, suspension, and other systems. You must be able to explain your findings and demonstrate how to check each component of the vehicle.
2. Basic vehicle control: You will demonstrate your ability to handle the vehicle in various situations, such as making tight turns, backing up in a straight line and in a curve, maneuvering through an alley dock, and parking in a designated spot.
3. On-road driving: You will drive the vehicle on public roads while being evaluated on your ability to safely operate the vehicle in traffic. This includes obeying traffic laws and signals, changing lanes, turning at intersections, merging onto highways, and other maneuvers.

Yes, the Utah DMV offers the Class B CDL written test in several languages other than English, including Spanish, Chinese, Korean, and Vietnamese. However, it's important to note that the skills test (the driving portion of the CDL test) is only offered in English.
If you choose to take the written test in a language other than English, you will need to select that language when scheduling your appointment at the DMV. You may also need to bring a translator with you to assist with any verbal instructions or explanations during the test.
Keep in mind that even if you take the written test in a language other than English, you will still need to demonstrate your ability to read and understand road signs and other traffic signals in English during the skills test.

Yes, if you have a disability that makes it difficult for you to take the Class B CDL written test under standard testing conditions, you may request accommodations from the Utah DMV.
To request accommodations, you will need to submit a request form and supporting documentation to the DMV at least 30 days prior to your scheduled test date. The documentation should include a diagnosis of your disability, as well as a description of how the disability affects your ability to take the test.
Examples of accommodations that may be provided include additional testing time, a separate testing room, or a reader or interpreter. The DMV will review your request and documentation and determine what accommodations are appropriate based on your individual needs and the requirements of the test.
It's important to note that accommodations are not guaranteed and may be denied if they fundamentally alter the nature of the test or compromise its validity.
