Arkansas CDL DMV Knowledge Test Class B 1

Cargo on a flatbed trailer should be secured by at least one tie-down for every 10 feet of the cargo's length. Cargo should be secured by a minimum of two tie-downs, regardless of size.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

You must have a hazardous materials endorsement to drive a vehicle of any size that is used to transport defined classes of hazardous materials.

If approaching a railroad crossing while driving a transit bus, school bus, or placarded vehicle, special procedures apply. Before crossing, stop your vehicle within 50 feet of, but not less than 15 feet from, the nearest rail. Activate your four-way flashers while crossing. Do not stop, change gears, or change lanes while any part of your vehicle is proceeding across the tracks.

The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles thereafter.

Most heavy-duty vehicles use dual air brake systems. A dual system has two separate air brake systems with a single set of controls.

The added weight of a heavy load will make a vehicle sit lower than usual. A vehicle will often be taller when carrying a light load than when carrying a heavy load. If your vehicle fits under an overpass while carrying a full load, it is not guaranteed that it will fit under the same overpass if it is empty.

To reduce the risk of a vehicle tipping over, the weight of cargo should be distributed as low as possible.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

When inspecting your brakes, you should check for cracked drums; shoes or pads covered in oil, grease, or brake fluid; and shoes that are missing, broken, or worn dangerously thin.

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

Large vehicles often have curved, convex mirrors, sometimes referred to as "fisheye," "spot," or "bug-eye" mirrors. These mirrors provide a wider view than flat mirrors. However, they also make objects seem smaller and farther away than they actually are.

The liver removes alcohol from the body at a fixed rate. Despite popular belief, tricks like drinking coffee or taking a cold shower will not speed up the process. The only way to become sober is to allow your body the time it needs to remove the alcohol from your system.

If you are asked to complete an offset back/right parking maneuver, you should first pull straight forward, then back up to the right. Your vehicle must be parked completely within the boundaries of the parking space.

During the CDL vehicle inspection test, you must be able to inspect your vehicle and explain to the examiner what you are inspecting and why.

The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles thereafter.

At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.

If you are convicted of any kind of traffic violation, in any type of vehicle, you must notify your employer within 30 days. You must also inform your motor vehicle licensing agency of the violation within 30 days if the conviction happened in another jurisdiction. This rule does not apply to parking infractions.

Vehicles with Anti-Lock Braking Systems (ABS) have yellow malfunction lamps.

Maximum axle weights are often set by a bridge formula, which sets a lower maximum weight for axles that are close together.

As the first step of a vehicle inspection, a driver should review any inspection report left by the previous driver.

In the event of a crash, a safety belt keeps the driver of a commercial motor vehicle securely positioned behind the steering wheel. This both protects the driver from injury and makes it easier for them to maintain control of the vehicle.

Cargo needs to be secured appropriately to prevent it from moving in transit. Cargo should be arranged to keep the vehicle's center of gravity low and well-distributed.

You must have a CDL to operate a vehicle that is designed to carry 16 or more people, including the driver.

Driving while distracted may result in slowed perception, delayed decision-making, and improper actions. Watch for distracted drivers and avoid them, when possible.

Whenever you pass another driver, bicyclist, or pedestrian, you should assume as a precaution that they do not see you.

A first conviction for operating a CMV while your blood alcohol concentration (BAC) is 0.04 percent or higher will result in the loss of your CDL for at least one year.

To ensure that you can see as well as possible, don't wear sunglasses when driving at night. If you wear eyeglasses, make sure they are clean and unscratched. Make sure you are rested and alert before driving at night.

When inspecting your vehicle, you should check the wiper blades for damage, stiff rubber, and proper securement.

If stopped on the side of the road, you must place emergency warning devices, such as reflective warning triangles, within 10 minutes of stopping.

Convex mirrors are also known as "fisheye", "spot", or "bug-eye" mirrors.

Ice cream trucks can create hazardous conditions for other drivers because they attract children. Children often do not notice or pay attention to other vehicles on the roadway when running to or from ice cream trucks.

To avoid engaging in dangerous and aggressive driving behavior, you should relax and accept any delays that arise throughout a trip. To help avoid the stress of arriving late to a destination, plan for likely delays when planning your drive.

If you must drive in reverse, you should first walk around the vehicle to check for hazards in your path of travel. Make frequent use of the mirrors on both sides of your vehicle while backing. Always back up as slowly as possible.

If you are asked to alley dock, you should first pull past the alley and stop your vehicle in a position that is parallel to the outer boundary. From there, you should back your vehicle entirely into the alley parking area. Your vehicle should be parked in a straight position within the boundaries of the parking space.
