Quote From Page 5 Of The CDL Manual:
Size of coil
All metal coil shipments that, individually or together, weigh 2,268 kg (5,000 lb.) or more must be secured according to the specific requirements in this section.
Exception: Metal coils that weigh less than 2,268 kg (5,000 lb.) may be secured according to general securement requirements.
- No more than 6 psi
- No more than 5 psi
- No more than 4 psi
- No more than 3 psi
Quote From Page 117 Of The CDL Manual:
With the engine running, build the air pressure to governed cut-out (100-125 psi). Shut off the engine, turn the electrical power on, chock your wheels, if necessary, release the tractor protection valve and parking brake (push in), fully apply the foot brake and hold it for one minute. Check the air gauge to see if the air pressure drops more than 3 pounds in 1 minute (single vehicle) or 4 pounds in 1 minute (combination vehicle) with brake applied. When brake is unapplied, air pressure drops more than 2 pounds in 1 minute with a single vehicle and 3 pounds in 1 minute in a combination vehicle.
TruckingTruth's Advice:
Be sure to memorize how much air loss is acceptable when the service brakes are applied and not applied.

- 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
- Back the tractor to the trailer on the right 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.
TruckingTruth's Advice:
It will take some practice, but always back under a trailer as straight as possible to avoid turning the trailer over.
- Check the the air lines and electrical line to be certain they are properly secured and connected
- Be sure the landing gear is fully raised, no missing parts, not bent or otherwise damaged
- Make sure the fifth wheel locking jaws are around the head of the kingpin and not the shank of the kingpin
- If you have a sliding fifth wheel, you must make sure the fifth wheel is securely locked in place
Quote From Page 78 Of The CDL Manual:
Inspecting a Combination Vehicle
- Locking jaws around the shank, not the head of kingpin.
- Landing gear is fully raised, no missing parts, not bent or otherwise damaged.
- Air lines properly connected to glad hands, no air leaks, properly secured with enough slack for turns.
- All sliding fifth wheel locking pins present and locked in place
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A vertical barrier across a vehicle to prevent forward movement of cargo.

- 2/32-inch
- 1-inch
- 4/32-inch
- 6/32-inch
Quote From Page 13 Of The CDL Manual:
You need at least 4/32-inch tread depth in every major groove on front wheels and 2/32-inch depth on other tires. No fabric should show through the tread or sidewall.
TruckingTruth's Advice:
You absolutely must memorize all legally allowed tread depths. This will probably show up on your written exam and will definitely need to be memorized for the pre-trip exam.
- Miles driven
- Road speed
- All of these answers are correct
- Engine use
Quote From Page 0 Of The CDL Manual:
Manufacturers of EOBRs must certify that their devices meet the minimum requirements. This includes a requirement that an EOBR must be mechanically or electronically connected to the truck to automatically record, at a minimum, engine use, road speed, miles driven, the date, and time of day. Drivers enter other information required to complete the hours-of-service records. The vast majority of EOBRs now use GPS tracking to meet these requirements.
TruckingTruth's Advice:
Most EOBRs are integrated within satellite communication systems that drivers and dispatchers use to communicate with each other.
- Opening the air tank petcock
- Brakes will be released when the electrical cable is attached
- If a dolly doesn't have spring brakes, it doesn't have brakes at all
- Hooking airlines to the dolly will automatically release the brakes
Quote From Page 80 Of The CDL Manual:

- When it is stacked long-ways on the trailer.
- Right after it is cut down.
- When it is painted green on the ends.

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.
