- All of these are reasons for front-wheel skids
- Driving too fast for conditions
- Too much tread on the front tires
- Cargo loaded so not enough weight is on the front axle
Quote From Page 44 Of The CDL Manual:
Front-Wheel Skids - Most front-wheel skids are caused by driving too fast for conditions. Other causes are lack of tread on the front tires, and cargo loaded so not enough weight is on the front axle. In a front-wheel skid, the front end tends to go in a straight line regardless of how much you turn the steering wheel. On a very slippery surface, you may not be able to steer around a curve or turn.
When a front-wheel skid occurs, the only way to stop the skid is to let the vehicle slow down. Stop turning and/or braking so hard. Slow down as quickly as possible without skidding.

General tiedown requirements
The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.
- Backing towards the drivers side offers better visibility than backing towards the right side
- Less accidents occur while backing towards the drivers side instead of the passenger side
- By backing towards the drivers side, you should be able to keep your window closed during inclement weather
- If you back and turn toward the driver's side, you can watch the rear of your vehicle by looking out the side window
Quote From Page 24 Of The CDL Manual:
Back to the driver's side so you can see better. Backing toward the right side is very dangerous because you cannot see as well. If you back and turn toward the driver's side, you can watch the rear of your vehicle by looking out the side window. Use driver-side backing-even if it means going around the block to put your vehicle in this position. The added safety is worth it.
Backing towards the passenger side is often referred to as "blind side backing." It is very dangerous due to low visibility and should be avoided whenever possible, especially in a combination vehicle.
- A system which uses parts of the service and parking brake systems to stop the vehicle in the event of a brake system failure.
- A system which applies and releases the parking brakes when you use the parking brake control
- A system used by mechanics during servicing do deactivate the emergency brakes
- A system which applies and releases the brakes when you use the brake pedal during normal driving
Quote From Page 62 Of The CDL Manual:
Air brake systems combine three braking systems: service, parking and emergency brake systems.
- 1. The service brake system applies and releases the brakes when you use the brake pedal during normal driving.
- 2. The parking brake system applies and releases the parking brakes when you use the parking brake control.
- 3. The emergency brake system uses parts of the service and parking brake systems to stop the vehicle in the event of a brake system failure.
It is vital that you learn the difference between the following definitions:
- Service Brake
- Parking Brake
- Emergency Brake
Memorize each definition and be sure you understand how each of these differ. Not only will this be critically important to passing the air brakes endorsement test but it is terminology you'll need to understand in the real world.
- Flash your brake lights to communicate you want the vehicle behind you to open their following distance
- Speed up to increase the distance between yourself and the vehicle behind you
- Make a quick lane change
- None of these answers are correct
Quote From Page 32 Of The CDL Manual:
If you are being tailgated, do the following to reduce the chances of an accident: Avoid quick changes. If you have to slow down or turn, signal early and reduce speed very gradually. Increase your following distance. Opening up room in front of you will help you avoid having to make sudden speed or direction changes. It also makes it easier for the tailgater to get around you. Do not speed up. It is safer to be tailgated at a low speed than a high speed. Avoid tricks. Do not turn on your taillights or flash your brake lights. Follow the suggestions above.
- A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
- A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
- A vehicle especially built and fitted with locking devices for transport.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")

- Lay the second layer horizontally.
- Be sure the bottom layer extends to the front of the vehicle.
- Make sure heavier rolls are on top.
- Stack the second layer at the back.
Quote From Page 6 Of The CDL Manual:
- Load paper rolls on a second layer only if the bottom layer extends to the front of the vehicle.
Prevent forward, rearward, or side-to-side movement:
- Either by the same means required for the bottom layer
- Or by the use of a blocking roll from a lower layer.
- A roll in the rearmost row of any layer must not be raised using dunnage.
- To prevent over-width trucks from becoming a hazard on narrow bridges
- To regulate the building of bridge structures so they can support the weight of heavy modern trucks
- To prevent the maximum tire load rating from being exceeded by narrow axle spacing
- To limit the weight-to-length ratio of a vehicle crossing a bridge.
Quote From Page 0 Of The CDL Manual:
- No obstacles should ever block an aisle or doorway which may trip other riders.
- Baggage can only be placed in an aisle if it is tied or secured to a seat
- Baggage can only be placed in the aisle if the owner of the baggage is available to move it when necessary
- Baggage may block doors as long as it is moved when the bus is loading or unloading passengers
Quote From Page 55 Of The CDL Manual:
Do not allow riders to leave carry-on baggage in a doorway or aisle. There should be nothing in the aisle that might trip other riders. Secure baggage and freight in ways that avoid damage and:
- Allow the driver to move freely and easily.
- Allow riders to exit by any window or door in an emergency.
- Protect riders from injury if carryons fall or shift.
Even if you don't plan on obtaining a CDL passenger endorsement, you will still required to have an understanding of some basic passenger rules and regulations for the written exam.
- Back the tractor to the trailer on the right side
- Back the tractor directly in front of the trailer
- Back the tractor to the trailer at a 45 degree angle on either the left or right side
- Back the tractor to the trailer on the left side
Quote From Page 75 Of The CDL Manual:
- Put the tractor directly in front of the trailer. (Never back under the trailer at an angle because you might push the trailer sideways and break the landing gear.)
- Check position, using outside mirrors, by looking down both sides of the trailer.
It will take some practice, but always back under a trailer as straight as possible to avoid turning the trailer over.
