Quote From Page 101 Of The CDL Manual:
Never park with Division 1.1, 1.2 or 1.3 (Class A or B) explosives within 5 feet of the traveled part of the road. Except for short periods of time needed for vehicle operation necessities (e.g. fueling), do not park within 300 feet of:
- a bridge, tunnel or building
- a place where people gather
- an open fire.
- The center point of the cargo's weight.
- The overall length of the cargo after being loaded into the trailer.
- The distance from the front of the trailer to the center point of the cargo.
- The average height of the cargo above the trailer floor.

- All of these are proper things to do after an accident involving hazardous materials
- Ask as many people standing nearby to come help control the spread of material
- Communicate the danger of the hazardous materials to emergency response personnel
- Provide emergency responders with the shipping papers and emergency response information
Quote From Page 102 Of The CDL Manual:
Accidents/Incidents - As a professional driver, your job at the scene of an accident is to:
- Keep people away from the scene.
- Limit the spread of material, only if you can safely do so.
- Communicate the danger of the hazardous materials to emergency response personnel.
- Provide emergency responders with the shipping papers and emergency response information.
Follow this checklist:
- Check to see that your driving partner is OK.
- Keep shipping papers and ERI with you.
- Keep people far away and upwind.
- Warn others of the danger.
- Send for help.
- Follow your employer's instructions.
- Try to stop the truck as quickly as possible by pressing as hard as you can into the brake pedal
- Release the brakes to get traction back
- There is no way to stop a trailer skid once it begins
- Use the trailer hand brake to help straighten out the trailer
Quote From Page 71 Of The CDL Manual:
Following is the procedure for stopping a trailer skid:
1. Recognize the skid. The earliest and best way to recognize that the trailer has started to skid is by seeing it in your mirrors. Any time you apply the brakes hard, check the mirrors to make sure the trailer is staying where it should be. Once the trailer swings out of your lane, it is very difficult to prevent a jackknife.
2. Stop using the brake. Release the brakes to get traction back. Do not use the trailer hand brake (if you have one) to "straighten out the rig." This is the wrong thing to do because the brakes on the trailer wheels caused the skid in the first place. Once the trailer wheels grip the road again, the trailer will start to follow the tractor and straighten out.
TruckingTruth's Advice:
Make certain you glance in your mirrors while stopping in slick conditions. It is very important to catch a jackknife early. The more the trailer swings into a jackknife, the harder it will be to recover.
- All of these answers are true
- When there are freezing temperatures and the brakes are very wet, the brake linings may freeze to the brake drums
- Older vehicles may have a round blue knob for the parking brake in place of the yellow diamond shaped knob currently used in modern equipment
- When the brakes are very hot (i.e. just after coming down a steep grade) wheel chocks should be used instead of the parking brake
Quote From Page 68 Of The CDL Manual:
Any time you park, use the parking brakes, except as noted. Pull the parking brake control knob out to apply the parking brakes. Push it in to release them. The control will be a yellow, diamond-shaped knob labeled "parking brakes" on newer vehicles. On older vehicles, it may be a round blue knob or some other shape, including a lever that swings from side to side or up and down.
Do not use the parking brakes if the brakes are very hot (i.e., from just coming down a steep grade), or if the brakes are very wet in freezing temperatures. If the brakes are used when very hot, they can be damaged by the heat. If they are used in freezing temperatures when the brakes are very wet, they can freeze so the vehicle cannot move. Use wheel chocks to hold the vehicle. Let hot brakes cool before using the parking brakes. If the brakes are wet, use the brakes lightly while driving in a low gear to heat and dry them.
If your vehicle does not have automatic air tank drains, drain your air tanks at the end of each working day to remove moisture and oil. Otherwise, the brakes could fail.
Never leave your vehicle unattended without applying the parking brakes or chocking the wheels. Your vehicle might roll away and cause injury and damage
- 100% of cargo weight.

g:
The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
- 2 latches each at or near both the front and rear.
- 4 latches total, anywhere on the trailer.
- 2 latches in the front and 2 in the middle.
- 2 latches in the middle, and 2 at the rear.
Quote From Page 8 Of The CDL Manual:
Secure the front and rear of the container independently.
- 2 latches on the chassis engage anchor points towards or at the front of the container.
- 2 latches on the chassis engage anchor points towards or at the rear of the container.
- Activates the emergency brakes when air pressure gets too high
- Ensures that air never stops flowing into the air storage tanks
- Detects any leaks in the airlines
- Controls when the air compressor will pump air into the air storage tanks
Quote From Page 62 Of The CDL Manual:
The governor controls when the air compressor will pump air into the air storage tanks. When air tank pressure rises to the "cut-out" level (around 125 pounds per square inch, or "psi"), the governor stops the compressor from pumping air. When the tank pressure falls to the "cut-in" pressure (around 100 psi), the governor allows the compressor to start pumping again.
