Delaware CDL Practice Test

Not quite. The answer is Life

If you are convicted of DUI for a second time, you will lose your CDL privileges for life. While you are driving a CMV, a blood alcohol concentration (BAC) of 0.04% or above qualifies as DUI. Your first offense is a wake-up call and a chance to get help, but your second offense is going to mean unemployment. If you get a DUI, seek help before you lose your salary and your future.

Not quite. The answer is Firefighters

Delaware offers a special Non-CDL license for farmers and firefighters who operate CMV’s under the CDL waiver provisions. Non-CDL licenses may not be used in interstate commerce or in for-hire situations.

Not quite. The answer is All of the above

The amount of off-tracking depends on three factors: the length of the vehicle, the sharpness of the curve or turn, and the amount of sideways drag on the rear tires. In general, the longer the vehicle, the greater the off-tracking. In a tractor-trailer, the amount of off-tracking depends on both the distance from the steering axle to the trailer kingpin, and the distance from the trailer kingpin to the trailer rear wheels. If your trailer is equipped with sliding tandems, then sliding the tandems backward will increase off-tracking. Also, the sharper the curve or turn, the greater the off-tracking. And the stronger the sideways drag on the rear tires, the greater the off-tracking.

Not quite. The answer is The driver is inspected but not the vehicle.

The Level 1 roadside inspection is the most comprehensive inspection. It involves a 37-point inspection of both the driver and the vehicle. The Level 2 inspection is similar, except that nothing underneath the vehicle is inspected. In a Level 3 inspection, the driver is inspected but not the vehicle. In a Level 5 inspection, the vehicle is inspected but not the driver.

Not quite. The answer is back and forth, near and far.

When driving your vehicle, look ahead a full 12–15 seconds. Be aware of what is happening all around your vehicle, both farther from it and closer to it. Keep shifting your attention back and forth, near and far, left and right, so that you can constantly scan all these areas.

Not quite. The answer is High beams

While driving at night, you should use your high beams to see farther as long as it is safe and legal and you will not blind any other drivers. Section 2.11.5 of the State of Delaware Commercial Driver License Manual recommends that you dim your headlights whenever you are within 500 feet of another vehicle.

Not quite. The answer is Use the parking brake to hold the vehicle until the clutch engages.

When you start your vehicle, avoid rolling backward or else you may hit someone behind you. Set the parking brake whenever necessary to keep from rolling back. Release the parking brake only when you have applied enough engine power to keep from rolling back. If you have a manual transmission vehicle, partly engage the clutch before you take your right foot off the brake. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep from rolling back.

Not quite. The answer is life.

The "No Human Trafficking on Our Roads" Act became law on January 8, 2018. On July 29, 2019, based on this law, FMCSA announced a new rule: Any driver who is convicted of human trafficking will be permanently banned from operating a CMV for which a CDL or a commercial learner’s permit (CLP) is required.

Not quite. The answer is 2

The rule is one tie-down for every ten feet of cargo but at least two tie-downs regardless of how small the cargo is.

Not quite. The answer is All of the above conditions must be met.

Section 405 of the Surface Transportation Assistance Act (STAA) protects you from employer retaliation if you refuse a task because you believe it violates federal laws or regulations or may result in serious injury to you or others. However, to be entitled to such protection, you must have first asked your employer to correct the problem, your employer refused to do it, you asked your employer for other work to perform, and any other reasonable person would agree with you about the violation or risk of serious injury. If your employer does retaliate against you for your refusal to do the task, you may file a complaint with the Occupational Safety and Health Administration (OSHA).

Not quite. The answer is 90 days.

Federal regulations define "coercion" as when a motor carrier, shipper, receiver, or transportation intermediary threatens to withhold work from, take employment action against, or punish a driver for refusing to operate in violation of federal regulations. The FMCSA's Coercion Rule explicitly prohibits motor carriers, shippers, receivers and transportation intermediaries from coercing drivers to operate in violation of certain FMCSA regulations. If you have been the victim of such coercion, you can file a coercion complaint with FMCSA, but you must do it within 90 days of when the coercion took place.

Not quite. The answer is Both of the above

Multi-speed rear axles (which tend to be less common in today's CMVs) and auxiliary transmissions provide additional gears that you can select while you drive. You select the additional gears with a control switch on the gearshift lever.

Not quite. The answer is All of the above

In your logbook, you must record each change of duty status, accurate to the nearest quarter hour (15 minutes). For each change, enter the location of the change and the reason for it in the Remarks section. Federal regulations refer to this information as an annotation, and electronic logging devices (ELDs) should have a way to enter such annotations electronically. Another use for the Remarks section is to record and annotate short-duration changes of duty status (those lasting less than 15 minutes), such as stopping for a few minutes to check the cargo securement. If you're temporarily exempt from some hours of service regulations because of an emergency or adverse condition, you should note that in the Remarks section, too. Finally, in the Remarks section, you should also identify the loads you picked up. One way (but not the only way) to identify a load is to enter the bill of lading number in the Remarks section.

Not quite. The answer is Type of tire tread

To determine which low gear to use to begin a descent, consider the weather, the length and steepness of the downgrade, the weight of your cargo, and the road conditions.

Not quite. The answer is There are “blind spots” that your mirrors cannot show.

"Blind spots" are areas around your vehicle that your mirrors cannot show you. Large CMVs have large blind spots to the front, the rear, and both sides of the vehicle. Convex mirrors can show a wider area than flat mirrors, but at the expense of making objects appear smaller and farther away than they would in a flat mirror.

Not quite. The answer is Do all of the above.

If you have a manual transmission vehicle, partly engage the clutch before you take your right foot off the brake. Set the parking brake whenever necessary to keep from rolling back. Release the parking brake only when you have applied enough engine power to keep from rolling back. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep from rolling back.

Not quite. The answer is 60 minutes.

According to federal regulation 49 CFR 393.95, acceptable warning devices include (1) three bidirectional reflective triangles; (2) six fusees, each of which can burn for at least 30 minutes; or (3) three flares, each of which can burn for at least 60 minutes. However, you may not use flares or fusees if your vehicle is carrying flammable or explosive hazardous materials. In that case, reflective triangles are your only option.

Not quite. The answer is 1/4 mile.

While driving, you should scan the road 12–15 seconds ahead. At 60 mph, your vehicle will travel a quarter of a mile in 15 seconds.

Not quite. The answer is Quieter operation

For large CMVs, diesel engines offer several advantages over gasoline engines. A diesel engine's high compression ratio gives it higher thermal efficiency, and therefore, about 25% greater fuel efficiency. Diesel engines produce a lot of power at low rpms. Diesel engines can last more than twice as long as gasoline engines (although this obviously depends on the specific models of engines). Finally, diesel fuel is safer than gasoline. Gasoline is highly flammable, and its vapors are highly explosive. Diesel fuel won't burn readily unless it's compressed (as in the cylinders of diesel engines). However, diesel engines are typically louder than gasoline engines.

Not quite. The answer is Both of the above

There are many things you must check during your pre-trip inspection. During Step 1 (Vehicle Overview) of the Seven-Step Inspection Method, check the condition of the windshield wipers. During Step 4 (Turn Off Engine and Check Lights) and Step 5 (Walk-Around Inspection), you'll check that the lights are working.
