- Performing an air brake inspection is voluntary
- You will receive an automatic failure
- You will be reminded of the oversight
- You will be docked 25 points
Quote From Page 117 Of The CDL Manual:
Air brake check (air brake-equipped vehicles only): Failure to perform an air brake check will result in an automatic failure of the Vehicle Inspection Test.
If you forget to perform an air brake check, you will be automatically disqualified and will need to retest. Further, the air brake check must be performed in a very specific order. If any step is done improperly or if you forget any step, that will also be grounds for disqualification. The proper steps to checking an air brake system is as follows:
- 1. With air pressure built up to 120 - 125 psi (fully charged system), depress the clutch and put the transmission into a low gear (keeping the transmission in gear will prevent the truck from rolling).
- 2. Shut the engine off, but turn the key back to the "on" position (this will allow you to hear the low air pressure warning alarm later in the test).
- 3. Release your foot off the clutch.
- 4. Release both the yellow tractor parking brake and the red trailer parking brake if equipped (remember, the truck is in gear so you won't roll - stay off the service brakes).
- 5. After air stabilizes (no sound of rushing air), fully apply the foot brake and hold it for one full minute (you can ask the examiner to time it for you). The system should not lose any more than 3 psi for a single vehicle and 4 psi for a combination vehicle in that minute. During this time, listen for any air leaks.
- 6. Begin "fanning" off the air pressure by rapidly pushing and releasing the foot brake. The low air warning light and buzzer should activate before pressure drops below 60psi.
- 7. Continue to fan the service brakes. At approximately 40 psi, the red tractor protection valve (trailer brakes) should pop out. Continue to fan off air pressure until the yellow tractor valve pops out (tractor brakes).
- 8. Put the transmission into neutral, depress the clutch, and restart the truck.

Bonus Tip: Stay Away From Caffeine!
Alright, well, you don't have to completely stay away from caffeine. Everyone needs a pick-me-up now and then. But remember, every time you stop, you are using up about 10 minutes from your log. By taking in a lot of caffeine, you'll certainly have to stop more frequently. You should try to limit your caffeine intake and as long as you're being safe and healthy, limit the amount of any fluids you're drinking. This may seem like a ridiculous tip, but drivers who "think outside the box" are generally rewarded with higher earnings. Remember, every minute counts!

Quote From Page 0 Of The CDL Manual:
- All of these inspections are true and correct
- Check pipes, connections and hoses for leaks
- Make sure manhole covers and vents have gaskets and that they close correctly
- Make sure intake, discharge, and cut-off valves are in the correct position before loading, unloading or moving the vehicle
Quote From Page 84 Of The CDL Manual:
On all tank vehicles, the most important item to check for is leaks. Check under and around the vehicle for signs of any leaking. Do not carry liquids or gases in a leaking tank. In general, check the following:
- Tank body or shell for dents or leaks.
- Intake, discharge and cut-off valves. Make sure valves are in correct position before loading, unloading or moving the vehicle.
- Pipes, connections and hoses for leaks, especially around joints.
- Manhole covers and vents. Make sure covers have gaskets and that they close correctly. Keep vents clear so they work correctly.
- Special purpose equipment. If your vehicle has any of the following equipment, make sure it works:
- Vapor recovery kits.
- Grounding and bonding cables.
- Emergency shut-off systems.
- Built-in fire extinguisher.
Make sure you know how to operate your special equipment. Check the emergency equipment required for your vehicle. Find out what equipment you are required to carry and make sure you have it (and it works).
- The rear trailer
- Both trailers are equally as likely to turn over
- The tractor is more likely to turn over than either trailer
- The front trailer
Quote From Page 70 Of The CDL Manual:
Trucks with trailers have a dangerous "crack-the-whip" effect. When you make a quick lane change, the crack-the-whip effect can turn the trailer over. There are many accidents where only the trailer has overturned.
"Rearward amplification" causes the crack-the-whip effect. The rear trailer is twice as likely to turn over as the tractor. You can roll the last trailer of triples 3.5 times as easily as a 5-axle tractor-semi.
When pulling more than 1 trailer, the rear-most trailer is always at a higher risk of overturning than the front trailer.
What violation has occurred at 8:00 a.m. on Day 2?
- There is a 14 hour rule violation
- There is an 11 hour rule violation
- There is no violation
- There is an 11 hour and 14 hour rule violation
Quote From Page 0 Of The CDL Manual:
Violations: There are 11 and 14 hour rule violations from 8:00 a.m. - 1:00 p.m. on Day 2.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver was eligible to drive for up to 11 hours beginning at 2:00 a.m. on Day 1. The driver reached the 11 hour driving limit at 3:00 p.m. on Day 1 and did not obtain another 10 hour break before driving again at 8:00 a.m. on Day 2, thus violating the 11 hour limit. The driver then obtained 8 consecutive hours in a sleeper berth, which, combined with the earlier 7 1/2 hour sleeper berth period, made the driver eligible for the split sleeper berth provision which means 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 11 hour calculation point to the end of the first of the two qualifying breaks, or 5:00 a.m. on Day 2. Between 5:00 a.m. and 9:00 p.m., the driver had 5 hours of driving, so at 9:00 p.m. on Day 2 there were 6 hours remaining, and there were no further 11 hour rule violations.
Explanation - 30 Minute Break: The driver was never on duty or driving for enough consecutive hours which would make 30 minute break mandatory, therefore the 30 minute break provisions does not apply in this example.
Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at 2:00 a.m. on Day 1. The 14 hour limit was reached at 4:00 p.m. on Day 1. Without a valid 10 hour break, the hours continued to accumulate into Day 2, and the driver violated the 14 hour rule by driving at 8:00 a.m. The driver then went into the sleeper berth for 8 consecutive hours, which enabled him or her to take advantage of the split sleeper berth provision. This moves the 14 hour calculation point to 5:00 a.m. on Day 2, the end of the first of the two qualifying breaks. Counting forward from there, the 8 hours from 5:00 a.m. to 1:00 p.m. are included in the calculation, but the 8 hour sleeper berth period is excluded. Therefore, at 9:00 p.m. on Day 2, the driver had 6 hours remaining and had no further violations of the 14 hour rule.
To remain in compliance: The driver should have remained in the sleeper berth until 5:30 a.m. on Day 2, thus moving the calculation point to 9:00 p.m. on Day 1. Or, at 9:00 p.m. on Day 1, the driver should have remained in the sleeper berth instead of going on duty for 30 minutes.
- Be free of oil and grease
- Be tilted down towards the rear of the tractor
- Be put in the manual lock position
- Have the jaws closed
Quote From Page 75 Of The CDL Manual:
Inspect Fifth Wheel Check for damaged/missing parts.
- Check to see that mounting to tractor is secure, no cracks in frame, etc.
- Be sure that the fifth wheel plate is greased as required. Failure to keep the fifth wheel plate lubricated could cause steering problems because of friction between the tractor and trailer.
- Check if fifth wheel is in proper position for coupling:
- Wheel tilted down towards rear of tractor.
- Jaws open.
- Safety unlocking handle in the automatic lock position.
- If you have a sliding fifth wheel, make sure it is locked.
- Make sure the trailer kingpin is not bent or broken.
