Oklahoma CDL: General Knowledge Practice Test

Not quite. The answer is Pulling forward while backing a trailer to reposition it

When backing a vehicle, especially a tractor-trailer, you may need to pull forward to straighten the vehicle or reposition it for a better angle. This corrective maneuver is called a pull-up. Note, however, that you should be able to back your vehicle successfully without too many such corrections. During your CDL skills test, your examiner may penalize you for too many pull-ups.

Not quite. The answer is You should review it during your pre-trip inspection.

Before performing the pre-trip inspection on your vehicle, review the previous driver's post-trip inspection report. Check whether all problems discovered by the last driver have been repaired.

Not quite. The answer is 2 years.

For violating an out-of-service order, a driver is normally disqualified for between 180 days and one year. However, if the driver was transporting hazardous materials or was driving a vehicle designed to transport at least 16 occupants including the driver, the driver will be disqualified for between 180 days and two years.

Not quite. The answer is Reduced braking power

Brakes use friction to convert the kinetic energy of your moving vehicle into heat. If the brakes get wet, the brake shoes or brake pads may produce less friction. The brakes will grab, apply unevenly, or become weak. When you try to brake, your braking distance may increase, your vehicle may pull to one side, or the wheels may lock. On a wet road, locked wheels can cause a skid (or even a jackknife if you're pulling a trailer).

Not quite. The answer is used when it is safe and legal to do so.

High beams will help you see farther ahead at night, making you a safer driver. However, to prevent blinding other drivers, dim your headlights whenever you are within 500 feet of an oncoming vehicle or within 500 feet of a vehicle you are following.

Not quite. The answer is Neither of the above

Components N and O are bearing plates.

Not quite. The answer is Vehicle frame

The vehicle frame is the main supporting structure of the vehicle, to which all other components are attached. It is supported by the vehicle's suspension.

Not quite. The answer is Tire damage

The sudden jerk from rough acceleration can cause mechanical damage. For example, it can damage the coupling if you're pulling a trailer.

Not quite. The answer is Your home terminal

According to federal regulation 49 CFR 395.8 and FMCSA Guidance FMCSA-HOS-ELD-TECH-395-FAQ26, you must record your duty status according to the time zone at your home terminal, including daylight savings time if it is in effect at your home terminal. Your "home terminal" is the place designated by your carrier, where you report for work at the start of your workday. Note that your carrier's main office may not be in the same time zone as your carrier's home terminal. Consider keeping a watch or smartphone app always set to your home terminal's local time so you can more easily log those times.

Not quite. The answer is If a hill or a curve keeps drivers behind you from seeing your vehicle within 500 feet, move the rear reflective triangle back down the road to give adequate warning.

If you must stop on a road or the shoulder of any road, turn on your four-way emergency flashers (not your taillights) and set out your emergency warning devices within ten minutes. If you stop beyond any hill, curve, or other obstruction that prevents other drivers from seeing your vehicle within 500 feet, place a reflective triangle up to 500 feet behind your vehicle to warn approaching drivers.

Not quite. The answer is the shipper and the carrier.

A bill of lading is a required document when shipping products by carrier. The bill of lading is issued by the carrier to the shipper, detailing the cargo that the carrier will transport for the shipper. It is a legally binding document. It includes the number of packages, a description of what is in each package, the weight of the packages, and the shipping rate. The bill of lading also lists the name and address of the shipper (consignor), and the name and address of the receiver (consignee). If there will be any Collect on Delivery (C.O.D.) charges, the bill of lading provides the necessary information, including who will pay the charges: the shipper or the receiver.

Not quite. The answer is On-duty time must be balanced with time for rest.

“Hours of service” (HOS) refers to the maximum amount of time that drivers are permitted to be on duty (including driving time). HOS regulations also specify the number and length of rest periods to help ensure that drivers stay awake and alert. In general, all carriers and drivers operating CMVs must comply with the HOS regulations in 49 CFR 395. Note: Effective September 29, 2020, several aspects of HOS regulations were revised. Among these changes: (1) A driver is required to take a break of at least 30 consecutive minutes after 8 cumulative hours of driving time. (2) A driver can meet the 10-hour minimum off-duty requirement by spending at least 7 hours of that period in the sleeper berth, combined with a minimum off-duty period of at least 2 hours spent inside or outside the berth, provided the two periods total at least 10 hours.

Not quite. The answer is All of the above can help.

There are a variety of ways to help prevent cargo theft, and you should employ several of them. First, be aware of your surroundings. While driving, check frequently whether you're being followed. Park only in well-lit, relatively secure locations. Stay in communication with dispatch. Whenever you stop at a rest area or truck stop, let dispatch know about it. An uncoupled trailer should be locked so it can't be moved. Kingpin locks and landing gear locks are available for this purpose. Always lock your truck whenever you must leave it unattended.

Not quite. The answer is The weight of a vehicle changes its height.

Your truck's height will vary depending on how much weight you're hauling. An empty or lightly loaded vehicle will ride higher than one that is weighed down with heavy cargo. Don't put all your trust in posted road clearance signs. The height of the roadway may have changed since the sign was posted.

Not quite. The answer is Your visibility

Always drive at a speed that lets you stop safely within the distance that you can see ahead. Otherwise, by the time you notice a hazard ahead of you, you may not be able to stop in time to avoid it.

Not quite. The answer is the tracks have a steep approach.

Raised railroad crossings with steep approaches can cause your vehicle to get hung up on the tracks. This is more likely if you're driving a vehicle with low ground clearance (such as a lowboy, car carrier, or moving van).

Not quite. The answer is Stop in a safe and legal location.

Federal regulations prohibit using a hand-held mobile phone while driving a CMV unless the phone is used to communicate with emergency services. Texting is prohibited even on hands-free devices, unless the text messages are used to communicate with emergency services. [49 CFR § 392.80],

Not quite. The answer is You could get hung up halfway across the tracks.

There may not be much space under your vehicle when it is heavily loaded. This is often a problem on dirt roads and in unpaved yards. If you try to cross a railroad track on a dirt road, your vehicle could get hung up halfway across the tracks. Be very careful when driving low-slung vehicles with little ground clearance to begin with, such as lowboys, car carriers, or moving vans.

Not quite. The answer is You can use the sound of the engine to tell you when to shift.

Learn the operating rpm range for your vehicle's engine. Watch your tachometer, and shift up when your engine reaches the top of the range. With practice, you can learn how your engine sounds when it reaches the top of the range. Then you can use the onset of that sound instead of the tachometer to tell you when to shift up. This way, you won't have to take your eyes off the road to check your tachometer every time you shift up. Double clutching is necessary only for unsynchronized manual transmissions.

Not quite. The answer is Stay off the brakes until the vehicle slows down on its own.

If a tire blows out, don't brake. Braking could cause you to lose control. Instead, let your vehicle slow itself down. Then brake very gently and pull over.
