Tennessee CDL Practice Test

Not quite. The answer is read the weight limit sign.

The maximum weight will be posted in advance of a bridge. After going over a bridge, you may be asked to tell the examiner what the posted weight limit was.

Not quite. The answer is requires a special transit permit.

Over-length, over-width, or overweight loads require special transit permits. Such loads may also require pilot vehicles, a police escort, or special equipment such as flags, flashing lights, or "Wide Load" signs. Driving is usually limited to certain times. Each state may specify its own requirements and procedures to follow. [49 CFR 393.11],

Not quite. The answer is Signal other drivers when it is safe for them to pass you.

If you must drive slowly, keep right and (if state laws allow it) use your four-way flashers to warn other drivers. Don't try to signal other drivers when you believe it's safe for them to pass you. If something were to go wrong, resulting in an accident, you could be held legally liable.

Not quite. The answer is 35 mph.

It's usually safest to drive at the speed of traffic rather than constantly pass other vehicles or invite other drivers to pass you. However, if there are lower speed limits posted for CMVs, obey them.

Not quite. The answer is Trucks, truck tractors, semitrailers, full trailers, and tractor-pole trailers with a gross vehicle weight rating of more than 10,000 pounds

Federal cargo securement rules apply to trucks, truck tractors, semitrailers, full trailers, and tractor-pole trailers with a gross vehicle weight rating of more than 10,000 pounds.

Not quite. The answer is on-time performance.

FMCSA's Compliance, Safety, Accountability (CSA) program includes the following seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe driving, crash indicator, Hours of Service compliance, vehicle maintenance, controlled substances/alcohol, hazardous materials compliance, and driver fitness. Carriers who fail to correct unsafe behaviors can be taken off the road. Your performance as a truck driver is an important part of your company's record.

Not quite. The answer is Basic chemistry

For a HazMat endorsement, you must learn which materials require placarding your vehicle and which materials cannot be loaded together. Your training will emphasize safe and responsible practices rather than scientific theory.

Not quite. The answer is 3

Your truck's emergency equipment must include warning devices such as three reflective red triangles, three liquid burning flares, or six fusees.

Not quite. The answer is 8

Under the Hours of Service regulations, after you've driven for 8 cumulative hours without a break, you must take a 30-minute break. Note that time that you spend on duty but not driving can be counted as part of the break.

Not quite. The answer is You may not be able to shift into a lower gear once you are going down a hill.

When you're about to start down a steep downgrade, release the gas pedal, shift into a low gear, and use engine braking to slow your vehicle. Don't try to downshift after your speed has already built up. You will not be able to shift into a lower gear then. You may not even be able to get back into any gear, and all engine braking effect will be lost. If you try to downshift an automatic transmission after your speed has already built up, you may damage the transmission.

Not quite. The answer is All of the above

Obstructive sleep apnea (OSA) is a medical condition in which a sleeping person repeatedly stops breathing for 10 seconds or more, caused by repeated closures of the upper airway. Physical effects of OSA include daytime sleepiness and reduced performance. OSA is quite common; 3 million Americans suffer from it. Risk factors for developing OSA include the male gender; ages 40 and older; obesity or overweight; a large neck size; and a family history of OSA. Many CMV drivers have several of these risk factors. Fortunately, the condition is treatable.

Not quite. The answer is Both of the above

You will be disqualified from operating a CMV for at least 60 days if you are convicted of any of the following offenses at railroad crossings: (1) failing to slow down and check that the tracks are clear; (2) failing to stop if a train is approaching; (3) failing to stop before driving onto the crossing; (4) failing to ensure that there is sufficient space for you to drive completely through the crossing without stopping; (5) failing to obey a traffic control device or the directions of an enforcement official; (6) failing to negotiate the crossing because of insufficient undercarriage clearance.

Not quite. The answer is Air brakes

Federal regulation 49 CFR 383.93 defines six different endorsements: Tank Vehicle, Hazardous Materials, Double and Triple trailers, Passenger, School Bus, and Combination tank vehicle and hazardous materials. According to federal regulation 49 CFR 383.95, a restriction on your CDL will prohibit you from operating vehicles with air brakes, until you pass the official knowledge test on air brakes and pass a skills test in a vehicle equipped with air brakes. Therefore, the qualification to drive vehicles with air brakes is NOT an endorsement, but the removal of a restriction that prohibits you from driving vehicles with air brakes.

Not quite. The answer is 6 months.

Under federal regulation 49 CFR 395.8, your carrier is responsible for keeping a copy of your duty logs and supporting documentation for six months. An example of supporting documentation is your fuel bills, with time stamps. As the driver, you must keep your copy of the log for today and the last 7 days.

Not quite. The answer is Yes.

Because of the limited visibility, avoid backing up whenever possible. If you must back your vehicle, use a helper if possible. The helper can stand near the rear of your vehicle and keep an eye on your blind spots. He or she can signal you to stop before an accident can occur.

Not quite. The answer is Level III

A Level III inspection is a driver inspection. The inspector interviews you and checks your CDL and other documents. The inspector checks whether you're wearing your seat belt. The inspector also looks for obvious signs of impairment on your part, such as being under the influence of alcohol. Finally, the inspector identifies and verifies your carrier to be sure it is authorized to operate in the country. Unlike Levels I and II, the inspector does not examine your vehicle or cargo.

Not quite. The answer is Brake shoes should not be worn dangerously thin.

When you check your brakes during your pre-trip inspection, check that the brake shoes are all present and none are broken or worn dangerously thin.

Not quite. The answer is Both of these answers are correct.

Federal regulations require shippers to warn drivers and others about the nature of the hazardous materials they are shipping. The shipper affixes US DOT-compliant HazMat labels to the packages and supplies the driver with the appropriate placards to attach to his or her vehicle. The shipper also notes the hazardous nature of the materials on the shipping papers. [49 CFR 172.400],

Not quite. The answer is 7 pounds.

One gallon of diesel fuel weighs about 7 pounds, meaning that a full fuel tank in a tractor-trailer can weigh well over 1,000 pounds. Bear this in mind when calculating how your vehicle can remain within legal weight limits.

Not quite. The answer is drive slowly around turns.

The higher the truck's center of gravity, the more likely it is to roll over. If the cargo is to one side, it will make the trailer lean, which can also make a rollover more likely. To help prevent a rollover, keep your cargo centered and as low as possible, and drive slowly around turns.
