Which violations have occurred in the below example?
- There is a 14 hour violation and a 30 minute break violation
- There is a 14 hour violation only
- There is a 14 hour violation and an 11 hour violation
- There is an 11 hour violation only
Quote From Page 0 Of The CDL Manual:
Violations: There is an 11 hour rule violation from 11:00 a.m. - 1:00 p.m., and a 14 hour rule violation from 7:00 a.m. - 1:00 p.m., both on Day 2.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. The driver did not have another 10 hour break (or the equivalent) until 1:00 p.m. on Day 2, so the calculation point never changes. The driver accumulated 7 total hours of driving on Day 1 and reached the 11 hour limit at 11:00 a.m. on Day 2. The violation began when the driver continued driving after that limit.
Explanation - 30 Minute Break: Since the longest consecutive stretch of on duty time was only 6 hours, the driver was never required to take a 30 minute break on either Day 1 or Day 2.
Explanation - 14 Hour Limit: Calculation of the 14 hour limit starts at 10:00 a.m. on Day 1. The 14 hour limit was reached at midnight, and the driver violated the 14 hour rule by driving a CMV starting at 7:00 a.m. on Day 2.
To remain in compliance: The driver should have stayed in the sleeper berth for one additional hour during one of the two sleeper berth breaks. This would have given the driver the equivalent of 10 hours off duty, making him or her eligible for the sleeper berth provision. This would have moved the calculation point to the end of the first of the two breaks (10:00 p.m. on Day 1) and the driver would have remained in compliance on Day 2, in this example.
- The farm equipment operator will be traveling further than 150 miles from his or her farm
- The operator is the spouse of the farm owner
- The farmer is transporting farm goods to a local market for commercial purposes
- Farm equipment operators are always exempt from obtaining a CDL provided they are transporting farm products, equipment or supplies to or from a farm
Quote From Page 3 Of The CDL Manual:
Farm Equipment Operators - This exemption covers legitimate farm-to-market operations by farmers, not commercial grain haulers. CDLs are not required to operate vehicles:
- Controlled and operated by a farmer, a member of the farmer's family or an employee;
- Used to transport farm products, equipment or supplies to or from a farm (including nurseries and aquacultures);
- Used within 150 air miles of the farm; and
- Not used in the operations of a common or contract carrier; and
- Used in nursery or agricultural operations.
NOTE: For the drivers of truck-tractor semitrailers, the farmer, his or her spouse and their children, parents on both sides, brothers and sisters on both sides and their spouses operating a truck-tractor semitrailer and meeting the above criteria also are exempted from the CDL Program. These drivers must be at least age 21, and the vehicle must have Farm plates. These drivers are still required to take the appropriate CDL written, skills and road tests to be licensed.
- Turn on a weather radio for temperature reports
- 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
- 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.
Quote From Page 130 Of The CDL Manual:
Select a safe speed, one that is not too fast for the weight of the vehicle, length and steepness of the grade, weather and road conditions. Once a safe speed has been reached, apply the brake hard enough to feel a definite slowdown.
- When speed has been reduced to 5 mph below the safe speed, release the brakes. (This application should last for about 3 seconds.)
Once speed has increased to the safe speed, repeat the procedure.
Example: If your “safe” speed is 40 mph, you should apply the brakes once your vehicle speed reaches 40 mph. Your brakes should be applied hard enough to reduce your speed to 35 mph. Once your vehicle speed reaches 35 mph, release the brakes. Repeat this procedure as often as necessary until you have reached the end of the downgrade. This braking technique is called "snubbing."
Avoid riding the brakes during steep downgrades and choose your correct gear before descending the hill.
- The yellow "parking brake" control valve
- The brake pedal
- The red "trailer air supply" control valve
- The trailer hand valve
Quote From Page 73 Of The CDL Manual:
The tractor protection valve keeps air in the tractor or truck should the trailer break away or develop a bad leak. The tractor protection valve is controlled by the "trailer air supply" control valve in the cab. The control valve allows you to open and shut the tractor protection valve. The tractor protection valve will close automatically if air pressure is low (in the range of 20 to 45 psi). When the tractor protection valve closes, it stops any air from going out of the tractor. It also lets the air out of the trailer emergency line. This causes the trailer emergency brakes to come on.
- Void filler
- Stake pocket
Quote From Page 2 Of The CDL Manual:
A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
Percentage of fuel weight to steer axle: 85%
Steer axle weight limit in states you're travelling: 20,000 pounds
Weight Before Fueling: Steer: 11,500, drives: 33,100, gross: 76,700
- 133 gallons of fuel
- 117.64 gallons of fuel
- 129.5 gallons of fuel
- 110.75 gallons of fuel
Quote From Page 0 Of The CDL Manual:
Because we know that 85% of the weight of fuel will go to the steer axle and you can add 850 pounds to your steer axle, we can plug the numbers into the formula above.
800/85 = 9.41
9.41 x 100 = 941
941/8 = 117.63 gallons of fuel you can add
- 172 gallons
- 148 gallons
- 119 gallons
- 100 gallons
Quote From Page 93 Of The CDL Manual:
Cargo tanks and other bulk containers require additional markings on the transport vehicle. "Bulk" is defined as a packaging with a maximum capacity greater than 119 gallons for liquid, including but not limited to such packagings as portable tanks, cargo tanks and tank cars. If required identification number markings on bulk containers are not visible while being transported (such as when loaded inside a closed semitrailer), the transport vehicle itself must also display on each side and each end the required identification number markings.
- No, the dolly should be removed after all trailers have been dropped to avoid damaging the trailer or dolly
- Yes, that way you can use the truck and first trailer to pull the dolly away from the rear trailer
- Removing the dolly before disconnecting is simply personal preference and it doesn't matter much either way
- No, you should never leave the rear trailer without a dolly attached to it
Quote From Page 81 Of The CDL Manual:
Uncouple rear trailer:
- Park in a straight line on firm level ground.
- Apply parking brakes so rig will not move.
- Chock wheels of second trailer if it does not have spring brakes.
- Lower landing gear of second semitrailer enough to remove some weight from-dolly.
- Close air shut-offs at rear of first semitrailer (and on dolly if so equipped).
- Disconnect all dolly air and electric lines and secure them.
- Release dolly brakes.
- Release converter dolly fifth wheel latch.
- Slowly pull tractor, first semi-trailer and dolly forward to pull dolly out from under rear semi-trailer.
- Only loading one layer of product to avoid a rollover
- Securing the front, back, or sides of a piece of cargo to keep it from sliding
- Placing cargo in the center of the trailer for proper load balance
- Putting a divider between the trailer doors and the product to keep anyone from seeing what product is being hauled
Quote From Page 53 Of The CDL Manual:
Blocking is used in the front, back and/or sides of a piece of cargo to keep it from sliding. Blocking is shaped to fit snugly against cargo. It is secured to the cargo deck to prevent cargo movement.
Bracing also is used to prevent movement of cargo. Bracing goes from the upper part of the cargo to the floor and/or walls of the cargo compartment.
