- Shippers prepare the route plan in advance and give the driver a copy
- Receivers prepare the route plan in advance and give the driver a copy
- Drivers are responsible for preparing their own route plan
- Carriers prepare the route plan in advance and give the driver a copy
Quote From Page 101 Of The CDL Manual:
If transporting Division 1.1, 1.2 or 1.3 (Class A or Class B) explosives, you must have a written route plan and follow that plan. Carriers prepare the route plan in advance and give the driver a copy. You may plan the route yourself if you pick up the explosives at a location other than your employer's terminal. Write out the plan in advance. Keep a copy of it with you while transporting the explosives. Deliver shipments of explosives only to authorized persons or leave them in locked rooms designed for explosives storage.
Which day below contains a 30 minute break violation?
Day 1
Day 2
- Both days contain at least one 30 minute break violation
- Day 2 contains at least one 30 minute break violation
- There are no 30 minute break violations on either day
- Day 1 contains at least one 30 minute break violation
Quote From Page 0 Of The CDL Manual:
Day 1
Day 2
Violations: There is a 30 minute break violation on Day 1 which occurred from 6:00 p.m. to 7:00 p.m. Then, on Day 2, there is another 30 minute break violation from 4:00 p.m. until 9:00 p.m. as well as an 11 hour rule violation from 4:00 p.m. - 9:00 p.m. and a 14 hour rule violation from 7:00 p.m. - 9:00 p.m.
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. After driving 8 hours (3 + 2 + 3), the driver took 8 consecutive hours in the sleeper berth, which, combined with the earlier 2 consecutive hours in the sleeper from 5:00 p.m. to 7:00 p.m. on Day 1, made the driver eligible for the split sleeper berth provision. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 9:00 p.m. on Day 1. Between 9:00 p.m. on Day 1 and 8:00 a.m. on Day 2, the driver had 3 hours of driving, so at 8:00 a.m. there were 8 hours remaining (11 - 3), but he or she continued to drive for an additional 5 hours, after reaching the 11 hour limit at 4:00 p.m.
Explanation - 30 Minute Break: On Day 1, the driver remained on duty for more than 8 consecutive hours. While remaining on duty for longer than 8 consecutive hours is perfectly legal, the driver may not operate a CMV after being on duty for more than 8 consecutive hours unless a 30 minute break is taken. In the Day 1 example, the driver didn't meet that requirement until being on duty for 9 hours (1 hour beyond the limit), thereby violating the 30 minute break provision from 6:00 p.m. to 7:00 p.m. The driver also failed to take a 30 minute break on Day 2. Since the driver was on duty (driving) for more than 8 hours beginning at 4:00 p.m., all drive time after 4:00 p.m. was in violation of the 30 minute break provision.
Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 10:00 a.m. on Day 1. The driver reached the 14 hour limit at midnight (the 2 hour sleeper berth period is included in the 14 hour calculation because it is less than 8 hours). The driver then entered the sleeper berth for 8 consecutive hours and took advantage of the split sleeper berth provision. This moves the 14 hour calculation point to 9:00 p.m. on Day 1, the end of the first of the two qualifying breaks. Counting forward from there (and excluding the 8-hour sleeper period), the driver had 11 hours remaining as of 8:00 a.m. on Day 2. Those 11 hours were used up by 7:00 pm
- Directly centered above the trailer tandems
- About 5-10 feet in front of the trailer tandems
- A little closer to the front than to the rear
- About 15 feet behind the tractor drive axles

TruckingTruth's Advice:
- The brake pedal
- The trailer hand valve
- The red "trailer air supply" control valve
- The yellow "parking brake" control 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.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- 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.
Quote From Page 2 Of The CDL Manual:
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- Turbo
- Camshaft
- Water pump
- All of these may be belt driven
Quote From Page 16 Of The CDL Manual:
Check belts for tightness and excessive wear (alternator, water pump, air compressor)-learn how much "give" the belts should have when adjusted right, and check each one.
TruckingTruth's Advice:
When checking any belts, be sure they aren't frayed, cracked, or broken.
- 100% of cargo weight.
- 10,000 lbs.
- 20% of cargo weight.
- 50% of cargo weight.
Quote From Page 2 Of The CDL Manual:
Note: Friction mats provide a resistance to horizontal movement equal to 50% of the cargo weight that is resting on the mat.
- Applying the brakes as hard as possible without locking the wheels
- Applying the brakes as hard as possible and locking the wheels
- Applying and releasing the brakes to avoid locking the wheels
- Applying only the trailer brakes using the trailer brake valve to avoid a jackknife
Quote From Page 43 Of The CDL Manual:
Controlled braking: With this method, you apply the brakes as hard as you can without locking the wheels. Keep steering wheel movements very small while doing this. If you need to make a larger steering adjustment or if the wheels lock, release the brakes. Reapply the brakes as soon as you can.
TruckingTruth's Advice:
A question about Controlled Braking and/or Stab Braking will likely show up on your written exam. Be sure to know the difference of each:
Controlled braking: With this method, you apply the brakes as hard as you can without locking the wheels.
Stab braking: Use only on vehicles without anti-lock brake systems.
- Apply your brakes all the way.
- Release brakes when wheels lock up.
- As soon as the wheels start rolling, apply the brakes fully again. (It can take up to 1 second for the wheels to start rolling after you release the brakes. If you reapply the brakes before the wheels start rolling, the vehicle will not straighten out.)
Note that most newer equipment (including trailers) have Anti-Lock Brake systems. That means controlled / stab braking is done automatically via the ABS system.
- Some road surfaces can cause a vehicle to tilt, but warning signs always account for that
- Road repaving or packed snow may reduce the clearance of the bridge since the sign was posted
- If you were able to clear a low bridge with a loaded trailer, you will be able to clear it with an empty trailer as well
- Bridge clearance signs always account for 3 inches of packed snow
Quote From Page 32 Of The CDL Manual:
Hitting overhead objects is a danger. Make sure you always have overhead clearance.
Do not assume that the weights and heights posted at bridges and overpasses are correct. Repaving or packed snow may have reduced the clearances since the heights were posted.
The weight of a cargo van changes its height. An empty van is higher than a loaded one. That you got under a bridge when you were loaded does not mean that you can do it when you are empty.
If you doubt you have safe space to pass under an object, go slowly. If you are not sure you can make it, take another route. Warnings are often posted on low bridges or underpasses, but sometimes they are not.
Some roads can cause a vehicle to tilt. There can be a problem clearing objects along the edge of the road, such as signs or trees or bridge supports. Where this is a problem, drive a little closer to the center of the road.
Before you back into an area, get out and check for over-hanging objects, such as trees, branches or electrical wires. It is easy to miss seeing them while you are backing. (Also check for other hazards at the same time.)
- To make pallets.
- To set cargo on top of.
- To reinforce blocking.
- To fill empty space between cargo.
