Quote From Page 0 Of The CDL Manual:
Violations: There is an 11 hour rule violation from 5:00 a.m. - 7:00 a.m. on Day 2.
Explanation - 11 Hour Limit: After 10 hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had 3 hours remaining, and exceeded the limit, by 2 hours, starting at 5:00 a.m. Then, because the driver accumulated at least 10 hours of rest using a combination of at least 8 consecutive hours in a sleeper berth and another break of at least 2 consecutive hours (in this case, 8), he or she was eligible for the split sleeper berth provision. This moves the calculation point to the end of the first of the two periods of rest, or 2:00 a.m. on Day 2. Between 2:00 a.m. and 3:00 p.m., the driver had 5 hours of driving, so at 3:00 p.m. on Day 2 there were 6 hours remaining, which the driver used by 9:00 p.m. Because the driver then took at least 2 consecutive hours off duty, he or she accumulated another 10 hours of rest in two separate, qualifying periods totaling 10 hours. This moves the calculation point again, to 3:00 p.m. on Day 2, and at 11:00 p.m. on Day 2 the driver has 5 hours of driving time remaining.
Explanation - 30 Minute Break: On Day 1, the driver required a 30 minute break at 6:00 p.m. in order to continue driving. But since the driver went into the sleeper berth and stayed there for 8 hours, the requirement was no longer needed. On Day 2, the driver never stayed on duty long enough to require a 30 minute break.
Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 10:00 a.m. on Day 1. The driver accumulates 8 hours of driving time by 6:00 p.m. before entering the sleeper berth. Because any sleeper berth period of at least 8 (but less than 10) consecutive hours is excluded from the 14 hour calculation, the driver accumulated just 13 hours by 7:00 a.m. on Day 2. The driver then met the requirements for the split sleeper berth provision, so the calculation point moves to the end of the first qualifying break, or 2:00 a.m. on Day 2. Starting from there, the driver accumulated 11 hours by 9:00 p.m. on Day 2. The driver again met the requirements for the split sleeper berth provision by getting 2 hours of rest, so the calculation point moves to 3:00 p.m. and the driver remains in compliance.
- Roof hatches should only be used as an emergency exit and should never be used as ventilation sources
- The height of the bus is calculated assuming the roof hatches will be open
- Roof hatches should be left open as regular practice
- You may lock some emergency roof hatches in a partly open position for fresh air.
Quote From Page 55 Of The CDL Manual:
You may lock some emergency roof hatches in a partly open position for fresh air. Do not leave them open as a regular practice. Keep in mind the bus's higher clearance while driving with them open.
Even if you don't plan on obtaining a CDL passenger endorsement, you will still required to have an understanding of some basic passenger rules and regulations for the written exam.
- Weigh more than 5,000 lbs, or have a volume of more than 1.25 cubic meters.
- Weigh more than 5,000 lbs, or have a volume of more than 4 cubic meters.
- Weigh more than 11,000 lbs, or have a volume of more than 2 cubic meters.
- Have more than five distinct sides.
Quote From Page 13 Of The CDL Manual:
The requirements in this section apply to any piece of natural, irregularly shaped rock that:
Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters
Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.
- None of these answers are correct
- Speed up to increase the distance between yourself and the vehicle behind you
- Flash your brake lights to communicate you want the vehicle behind you to open their following distance
- Make a quick lane change
Quote From Page 32 Of The CDL Manual:
If you are being tailgated, do the following to reduce the chances of an accident: Avoid quick changes. If you have to slow down or turn, signal early and reduce speed very gradually. Increase your following distance. Opening up room in front of you will help you avoid having to make sudden speed or direction changes. It also makes it easier for the tailgater to get around you. Do not speed up. It is safer to be tailgated at a low speed than a high speed. Avoid tricks. Do not turn on your taillights or flash your brake lights. Follow the suggestions above.
- You will regain 8 hours on your 14 hour on duty time
- Spending 8 hours in the sleeper berth will completely reset your 14 hour on duty time and your 11 hour driving time
- Those hours will not count as part of your 14 hour on duty time, and therefore, would allow you to extend the time during which you could use your maximum 11 hours of driving
- Spending 8 hours in the sleeper berth will completely reset your 60/70 hour on duty clock
Quote From Page 0 Of The CDL Manual:
Eight hours of sleeper berth time:
You may also use the sleeper berth to extend the 14 hour limit. Any period in the sleeper berth of at least 8 consecutive hours will not count as part of the 14 hours, and, therefore, would allow you to extend the time during which you could use your maximum 11 hours of driving.
Basically, when you take an 8 hour break in the sleeper berth, your time simply extends. You can't reset your hours completely, but those 8 hours will not count against your 14 hour on duty time.
In other words, let's say you have the following hours remaining:
- 14 hour duty clock: 7 hours
- 11 hour driving clock: 6 hours
If you go into the sleeper berth, in 8 hours you will still have the same time remaining.
If you had taken 10 consecutive hours off instead, your 14 and 11 hour limits would have completely reset. That's why the 8 hour sleeper berth rule should only be used when necessary. Normally this rule is used when it is necessary in order to make a delivery legally and on-time.
- A ramp to connect an expressway to a side street
- A traffic device that enables vehicles that are having braking problems to safely stop
- A device used to help climb into or out of a truck trailer
- Another term for an on-ramp, connecting a side street to a major expressway
Quote From Page 43 Of The CDL Manual:
Brake failure on downgrades: Going slow enough and braking properly will almost always prevent brake failure on long downgrades. Once the brakes have failed, however, look outside your vehicle for something to stop it.
Your best hope is an escape ramp. If there is one, there will be signs posted. Ramps are usually located a few miles from the top of the downgrade. Every year, hundreds of drivers avoid injury to themselves or damage to their vehicles by using escape ramps. Some escape ramps use soft gravel that resists the motion of the vehicle and brings it to a stop. Others turn uphill, using the hill to stop the vehicle and soft gravel to hold it in place.
Any driver who loses brakes going downhill should use an escape ramp if available. If you do not use it, your chances of having a serious accident may be much greater. If no escape ramp is available, take the least hazardous escape route you can, such as an open field or a side road that flattens out or turns uphill. Make the move as soon as you know your brakes do not work. The longer you wait, the faster the vehicle will go and the harder it will be to stop.
- Straddle both lanes until you're up to speed in order to prevent vehicles from passing
- Move into the left-most lane
- Accelerate as slowly as possible
- Make sure the turn signal is off
Quote From Page 128 Of The CDL Manual:
After the turn:
- Make sure turn signal is off.
- Get up to speed of traffic, use turn signal, and move into right-most lane when safe to do so (if not already there).
Semi-trucks do not come with self-cancelling turn signals. You must cancel turn signals manually. Therefor, it is extremely important to remember to cancel your turn signal after making a turn. Driving with your turn signal on is not only very dangerous, it will cost you points during the driving exam.

- Your logbook can be randomly checked anytime you go through a weigh station
- Non-DOT law enforcement officers need probable cause to inspect your logbook
- The increased use of electronic logging devices has forced carriers to crack down on HOS violations
- Your logbook can be checked by your carrier at anytime
Quote From Page 0 Of The CDL Manual:
Who Enforces HOS Regulations?
Generally, DOT officers are the ones who enforce HOS rules, although any police officer may inspect a driver's logbook. Individual states are responsible for maintaining weigh stations where drivers are pulled in for random vehicle and logbook inspections. Drivers may also be pulled over for random checks by police officers or DOT officials at any time and have their logbooks inspected. While it's not a frequent occurrence, chances are your logbook will be checked every now and then. Be ready for it at all times!
In addition to law enforcement and DOT officials, most carriers have their own company policies regarding logbooks. A drivers logs are frequently reviewed by internal auditors for discrepancies or violations. A driver with too many violations might be warned, disciplined, or terminated (terminating a driver usually only occurs after several violations). The increased use of electronic logging devices (discussed later) has forced carriers to crack down on HOS violations even more.
Your logbook could be checked at anytime for any reason. Make sure it is always updated!
What violations occurred on Day 2 of this example?
- There is a 14 and 11 hour rule violation
- There is an 11 hour rule violation and a 30 minute break violation
- There is a 14 and 11 hour rule violation as well as a 30 minute break violation
- There is a 14 hour rule violation and a 30 minute break violation
Quote From Page 0 Of The CDL Manual:
Violations: There are a total of 3 violations on Day 2. First, there is a 14 hour rule violation from 1:00 a.m. - 2:00 a.m. Second, there is a 30 minute break violation from 8:00 p.m - midnight. And third, there is also an 11 hour rule violation from 11:00 p.m. - midnight.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty using a combination of off duty and sleeper berth time, the driver was eligible to drive for up to 11 hours starting at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had driven 9 hours. By obtaining 10 consecutive hours off duty on Day 2, the 11 hour calculation point moved to noon on Day 2, at which point the driver had 11 hours of driving time available again. The driver violated the 11 hour rule by driving beyond the 11 hour limit between 11:00 p.m. and Midnight.
Explanation - 30 Minute Break: On Day 1, the driver was never required to take a 30 minute break because the longest stretch of on duty time during the entire day was only 6 consecutive hours. On day 2, the driver never took a minimum of 30 consecutive minutes off duty, even after remaining in the driver's seat for more than 8-hours. At 8:00 p.m. the driver was in violation of the 30 minute break provision and remained in violation for the remainder of the day.
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 5-hour sleeper-berth period is included in the 14 hour calculation because it was less than 8 hours). Though the driver was not eligible to drive a CMV after midnight, he or she was able to continue working on duty without violation, as long as no driving took place (which was done for 1 hour). The driver violated the 14 hour rule by driving a CMV at 1:00 a.m. Then, after 10 consecutive hours off duty, the 14 hour calculation point moved to noon on Day 2, at which point the driver had 14 hours available to work again.
