These Questions Are From The Illinois CDL Manual
- Shows how much air pressure you are applying to the brakes
- Let's you know when air pressure in the tanks are too low
- Application pressure gauges must be installed on all commercial vehicles
- Tells you how much pressure is in the air tanks
Quote From Page 64 Of The CDL Manual:
Application Pressure Gauge - This gauge shows how much air pressure you are applying to the brakes. (This gauge is not on all vehicles.) Increasing application pressure to hold the same speed means the brakes are fading. You should slow down and use a lower gear. The need for increased pressure also can be caused by brakes out of adjustment, air leaks or mechanical problems.
- They tell shippers how to package the materials safely and drivers how to load, transport and unload the materials
- Rules for isolating a spilled hazardous material
- Requirements that state trucks carrying hazardous materials are not allowed in residential neighborhoods
- Require all different classes of hazardous materials to be shipped in separate trailers to avoid mixing of chemicals
Quote From Page 87 Of The CDL Manual:
Transporting hazardous materials can be risky. The regulations are intended to protect you, those around you, and the environment. They tell shippers how to package the materials safely and drivers how to load, transport and unload the materials. These are called "containment rules."
- Right after it is cut down.
- When it is stacked long-ways on the trailer.
- When it is painted green on the ends.
- When it is embedded in a stack of longwood.
Quote From Page 3 Of The CDL Manual:
What's in a stack?
Some stacks may be made up of both shortwood and longwood. Any stack that includes shortwood must follow the shortwood securement requirements.
Exception: If shortwood is embedded in load of longwood, it can be treated as longwood.
- Initial methods of handling spills, fires and leaks of the materials.
- How to fight a fire started by the type of material being shipped
- How to safely handle incidents involving the material being shipped
- Information on the shipping name of the hazardous materials, risks to health, fire, and explosion
Quote From Page 93 Of The CDL Manual:
Shippers also must provide emergency response information to the motor carrier for each hazardous material being shipped. The emergency response information must be able to be used away from the motor vehicle and must provide information on how to safely handle incidents involving the material. It must include information on the shipping name of the hazardous materials, risks to health, fire, explosion, and initial methods of handling spills, fires and leaks of the materials.
Such information can be on the shipping paper or some other document that includes the basic description and technical name of the hazardous material. Or, it may be in a guidance book such as the Emergency Response Guidebook (ERG). Motor carriers may assist shippers by keeping an ERG on each vehicle carrying hazardous materials. The driver must provide the emergency response information to any federal, state or local authority responding to a hazardous materials incident or investigating one.
- They are used to supply air to the emergency brakes in the event of an air compressor failure
- They are used to hold compressed air for the air brake system
- They are used to supply air to the air compressor
- They are used to transport air from the tractor to the trailer on combination vehicles
Quote From Page 62 Of The CDL Manual:
Air storage tanks are used to hold compressed air. The number and size of air tanks vary among vehicles. The tanks will hold enough air to allow the brakes to be used several times even if the compressor stops working.
In an air brake system, emergency brakes naturally want to activate. It is the air pressure which holds the emergency brakes back and keeps them from activating. Therefor, air is not required for emergency brakes to function. Rather, if air is depleted from the air tanks, the emergency brakes will automatically engage.
- Ask other drivers over the CB radio if icing is present
- Open the window and feel the front of the mirror, mirror support or antenna. If there is ice on them, the road surface is probably starting to ice up
- Turn on a weather radio for temperature reports
- Stop on the shoulder of the road so you can get out and manually check the roadway surface for ice
Quote From Page 29 Of The CDL Manual:
An easy way to check for ice is to open the window and feel the front of the mirror, mirror support or antenna. If there is ice on them, the road surface is probably starting to ice up.
- Lightly ride the clutch during the grade
- To avoid engine damage, put the gear in neutral and coast down the hill
- Do not change gears while driving down a grade
- Race the engine to improve engine braking
Quote From Page 130 Of The CDL Manual:
When operating any commercial vehicle, do not ride the clutch, race the engine, change gears or coast while driving down the grade. At the bottom of the grade, be sure to cancel the 4-way flashers.
Always slow down and be in proper gear before a downgrade and never change gears or coast during the downgrade.
- 2 latches in the front and 2 in the middle.
- 2 latches in the middle, and 2 at the rear.
- 4 latches total, anywhere on the trailer.
- 2 latches each at or near both the front and 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.
- 75 in
- Half the length of the trailer.
- 16 ft
- The width of the road.
Quote From Page 3 Of The CDL Manual:
- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.
- Cut-up logs
- Cut-to-length logs
- All of these things must be checked
- High-beam headlights
- Brake lights
Quote From Page 118 Of The CDL Manual:
Lights/reflectors: Check that all external lights and reflective equipment are clean and functional. Light and reflector checks include:
- Clearance lights (red on rear, amber elsewhere)
- Headlights (high and low-beams); taillights
- Turn signals
- 4-way flashers
- Brake lights
- Red reflectors (on rear) and amber reflectors (elsewhere)
Note: Checks of brake turn signal and 4-way flasher functions must be done separately.
While it may get a bit repetitive, during the pre-trip exam you need to point out and identify every light and reflector on both the truck and the trailer. Make sure all lights and reflectors are functioning properly, are clearly visible, properly mounted and secured, and not cracked or broken.
