) to help you understand the materials better and gain an understanding for how that knowledge will fit into the overall picture.
"My own experience with the course itself was nothing short of amazing. To come into
the course with absolutely no prior knowledge of the subject, and to be able to grasp
the information, understand it, and retain it, has taken quite a bit off stress off me.
Now I know that when I do enroll in a school, I can focus on the driving aspects, and not
have to worry about the classroom side of things.

On what day and time does an 11 hour rule violation occur?
Day 1
Day 2
- There is no 11 hour rule violation on either day of this example
- Day 2 at 3:00 a.m.
- Day 1 at 6:00 p.m.
- Day 2 at 5:00 a.m.
Quote From Page 0 Of The CDL Manual:
Day 1
Day 2
Violations: There is a 30 minute break violation from 6:00 p.m. to 7:00 p.m. on Day 1. On Day 2, there is an 11 hour rule violation from 5:00 a.m. - 6:00 a.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. At the end of the day, the driver had 2 hours remaining and, without a valid 10 hour break, the driver violated the 11 hour limit by driving an additional 1 hour at 5 a.m. on Day 2.
Explanation - 30 Minute Break: As soon as the driver went into an on duty status (driving) at 10:00 a.m. on Day 1, the driver was allowed an 8 consecutive hour time frame to drive a CMV until a 30 minute break had to be taken. The driver did not stop driving until 9 hours had passed, thus violating the 30 minute break provision from 6:00 p.m. to 7:00 p.m. on Day 1. On Day 2, the driver was only on duty for a total of 3 hours which does not 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 used 9 of 14 available hours on Day 1. Because the driver then got at least 8 consecutive hours in a sleeper berth from 7:00 p.m. on day 1 until 3:00 a.m. on Day 2, that rest break is not included in the 14 hour calculation. The new 14 hour limit calculation point was then 3:00 a.m. with 5 hours remaining (14 available hours - 9 hours used on Day 1). At 6:00 a.m. the driver switched to off duty for the remainder of the day with 2 hours remaining on the 14 hour limit.
What violation has occurred at 10:00 a.m. on Day 2?
Day 1
Day 2
- There is a 30 minute break violation
- There is an 11 hour rule violation
- There is a 14 hour rule violation
- There is no violation at 10:00 a.m.
Quote From Page 0 Of The CDL Manual:
Day 1
Day 2
Violations: There is an 11 hour rule violation from 12:30 p.m. - 1:00 p.m., and a 14 hour rule violation from noon - 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. After 7 1/2 hours of driving (3 + 2 1/2 + 2), the driver entered the sleeper berth for 2 consecutive hours, making him or her eligible for the split sleeper berth provision. The driver accumulated at least 10 hours of rest using a combination of at least 8 (but less than 10) consecutive hours in a sleeper berth and another break of at least 2 (but less than 10) consecutive hours. This moves the calculation point to the end of the first of the two qualifying periods of rest, or 10:00 p.m. on Day 1. The next 11 hour calculation starts there, and the driver reached the 11 hour driving limit at 12:30 p.m. on Day 2 but still continued to drive for another 1/2 hour.
Explanation - 30 Minute Break: On both Day 1 and Day 2, the driver never spent more than 8 consecutive hours on duty or driving and therefore, no violation occurred on either day.
Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 10:00 a.m. on Day 1. At midnight on Day 1, the driver still had 9 hours remaining because any sleeper berth period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation. By 4:00 a.m. on Day 2, the driver had 5 hours remaining (14 - 3 - 2 1/2 - 1 1/2 - 2 = 5). The driver then took a break of at least 2 consecutive hours, making him or her eligible for the split sleeper berth provision. This moves the calculation point to the end of the first of the two qualifying periods of rest, or 10:00 p.m. on Day 1. The next 14 hour calculation starts there, and the driver reached the end of the 14 hour duty period at noon on Day 2 and drove for 1 hour over the 14 hour limit.

- Brake Lag Distance
- Applied Friction Distance
- Effective Braking Distance
- Reaction Distance
Quote From Page 68 Of The CDL Manual:
With air brakes, there is an added delay - the time required for the brakes to work after the brake pedal is pushed. With hydraulic brakes (used on cars and light/medium trucks), the brakes work instantly. However, with air brakes, it takes a little time (one-half second or more) for the air to flow through the lines to the brakes. Thus, the total stopping distance for vehicles with air brake systems is made up of four different factors:
Perception Distance
+ Reaction Distance
+ Brake Lag Distance
+ Effective Braking Distance
---------------------------
= Total Stopping Distance
TruckingTruth's Advice:
Be certain you have the stopping distance formula memorized as it will almost definitely show up on your written exam.
- Less than 12 seconds of following distance
- Less than 400ft of following distance
- Failure of a truck to leave sufficient distance for being overtaken by another vehicle
- Less than 8 seconds of following distance
Quote From Page 9 Of The CDL Manual:
Following Too Closely:
- Following the vehicle ahead too closely.
- Failure of a truck to leave sufficient distance for being overtaken by another vehicle.
TruckingTruth's Advice:
While the CDL manual specifically states "failure of a truck to leave sufficient distance for being overtaken by another vehicle" there are many scenarios in which a driver can be charged with following too closely. But that is the answer you'll most likely see if asked on an exam.
Following too closely is considered a serious traffic violation and carries with it additional consequences. Two serious traffic violations within a three-year period results in a two-month disqualification. Three serious traffic violations in the same period results in a four-month disqualification.
Following too closely is one of the most dangerous things you can do. Keeping plenty of following distance is absolutely critical to safe driving.

Quote From Page 3 Of The CDL Manual:
Tiedowns must be arranged in the following manner to prevent the coils from tipping in the forward, rearward and side-to-side (lateral) directions:
- At least one indirect tiedown attached diagonally from the left side of the vehicle, across the eye of the coil, to the right side of the vehicle;
- At least one indirect tiedown attached diagonally from the right side of the vehicle, across the eye of the coil, to the left side of the vehicle;
- At least one indirect tiedown attached side-to-side over the eye of the coil;
- These are all part of method #1.
- Attach at least one indirect tiedown side-to-side over the top.
- Support the coil above the deck.
- Attach at least one tiedown through the eye diagonally each way.
Quote From Page 3 Of The CDL Manual:
Step #1: Support the coil above the deck to prevent the coil from rolling.
Step #2: Attach at least one direct tiedown on each diagonal through the eye of the coil making an angle not more than 45 degrees with the floor of the vehicle when viewed from the side.
Attach at least one indirect tiedown side-to-side over the top of the coil.
Use blocking or friction mats to prevent forward movement.
