Quote From Page 0 Of The CDL Manual:
The 14 Hour On Duty Limit
This limit is usually thought of as a "daily" limit, even though it is not based on a 24 hour period. You are allowed a period of 14 consecutive hours of on duty time after being off duty for 10 or more consecutive hours. The 14 consecutive hour duty period begins when you start any kind of reportable work (performing vehicle maintenance, loading / unloading cargo, fueling, driving, etc.). Once you have reached the end of this 14 consecutive hour period, you cannot drive again until you have been off duty for another 10 consecutive hours.
Your driving is limited to the 14 consecutive hour on duty period even if you take some off duty time, such as a lunch break or a nap, during those 14 hours.
While you are only allowed 11 hours of driving after taking a 10 consecutive hour break, you are able to complete those 11 hours at any point during the 14 hour limit.
- Bulkheads are only allowed in food-grade tankers where baffles can be installed in any type of tanker
- Baffles are solid barriers in a tanks while bulkheads are barriers with holes in them, allowing liquid to flow through
- Bulkheads are only used in gas tankers and baffles are only used in liquid tankers
- Bulkheads are solid barriers in a tank while baffles are barriers with holes in them, allowing liquid to flow through
Quote From Page 84 Of The CDL Manual:
Bulkheads: Some liquid tanks are divided into several smaller tanks by bulkheads. When loading and unloading the smaller tanks, the driver must pay attention to weight distribution. Do not put too much weight on the front or rear of the vehicle.
Baffled tanks: Baffled liquid tanks have bulkheads in them with holes that let the liquid flow through. The baffles help to control the forward and backward liquid surge. Side-to-side surge can still occur. This can cause a roll over.
- 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
- Less accidents occur while backing towards the drivers side instead of the passenger side
- Backing towards the drivers side offers better visibility than backing towards the right side
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.
- prevent it from tipping that may also prevent it from shifting.
- Attach to a tiedown.
- receive a stake or peg, and may also be used as an anchor point.
- provide greater friction than exists naturally between these surfaces.

- The front wheels lock and the drive wheels do not
- The rear drive wheels lock up
- The rear tires have more tread than the front tires
- The rear tires have more friction than the front tires
Quote From Page 44 Of The CDL Manual:
Rear-wheel braking skids occur when the rear-drive wheels lock.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Quote From Page 2 Of The CDL Manual:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- Slow down by downshifting to avoid coasting
- Keep the truck in gear and depress the clutch pedal before slowing down
- Put the truck in the highest possible gear before slowing down
- Put the truck in neutral before using the brake pedal to slow down
Quote From Page 128 Of The CDL Manual:
As you approach the turn:
- Use turn signals to warn others of your turn.
- Slow down smoothly, change gears as needed to keep power, but do not coast unsafely. Unsafe coasting occurs when your vehicle is out of gear (clutch depressed or gearshift in neutral) for more than the length of your vehicle.
The examiners will check to make sure you're able to keep the truck in gear by using proper downshifting. Avoid taking the truck out of gear until absolutely necessary.

- No more than 5 psi
- No more than 4 psi
- No more than 2 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.
Be sure to memorize how much air loss is acceptable when the service brakes are applied and not applied.
