- The trailer will be forced downward into the fifth wheel plate, causing damage to the ground or landing gear
- It may not couple correctly
- Modern trucks are installed with a "trailer height icon" which will illuminate on your dashboard
- The fifth wheel plate will automatically adjust to the trailer height
Quote From Page 75 Of The CDL Manual:
Check Trailer Height
- The trailer should be low enough that it is raised slightly by the tractor when the tractor is backed under it. Raise or lower the trailer as needed. (If the trailer is too low, the tractor may strike and damage the nose of the trailer; if the trailer is too high, it may not couple correctly.)
- Check that the kingpin and fifth wheel are aligned.
In addition to incorrect coupling, if a trailer is too high off the ground and you try to back into it, you may cause damage as the rear of your truck cab could strike the front of the trailer. Further, the trailer king pin may become stuck in front of the fifth wheel plate which can be a costly and time wasting error. Before backing under any trailer, it's very important to visually check the trailer height in relation to your tractors fifth wheel.
- When coming to a stop, the liquid will surge back and forth
- When the surge hits the end of the tank, it tends to push the truck in the opposite direction the wave is moving
- Results from movement of the liquid in partially filled tanks
- If the truck is on a slippery surface such as ice, the wave can shove a stopped truck out into an intersection
Quote From Page 84 Of The CDL Manual:
Liquid surge results from movement of the liquid in partially filled tanks. This movement can have bad effects on handling. For example, when coming to a stop, the liquid will surge back and forth. When the wave hits the end of the tank, it tends to push the truck in the direction the wave is moving. If the truck is on a slippery surface such as ice, the wave can shove a stopped truck out into an intersection. The driver of a liquid tanker must be very familiar with the handling of the vehicle.
- All time inspecting or servicing your truck, including fueling
- All of these are considered on duty time
- All time loading and unloading your truck
- All driving time
Quote From Page 0 Of The CDL Manual:
What Is Considered On Duty Time?
The 60 / 70 hour limit is based on how many hours you work over a 7 or 8 day period. Just what kind of work is considered on duty time? It includes all time you are working or are required to be ready to work, for any employer. Here are some specific activities which are considered to be on duty time:
- All time spent at a plant, shipping / receiving facility, terminal, or other facility of a motor carrier, unless you are in your sleeper berth or have been relieved of all work related responsibilities.
- All time inspecting or servicing your truck, including fueling it and washing it.
- All driving time.
- All other time in a truck unless you are resting in a sleeper berth.
- All time loading, unloading, supervising, or attending your truck; or handling paperwork for shipments.
- All time spent providing a breath, saliva, hair, or urine sample for drug / alcohol testing, including travel to and from the collection site.
- All time spent doing any other work for a motor carrier, including giving or receiving training and driving a company car.
- All time spent doing paid work for anyone who is not a motor carrier, such as a part-time job at a local restaurant.
The bottom line is that on duty time includes all time you are working for a motor carrier, whether paid or not, and all time you are doing paid work for anyone else.
- Hold the steering wheel firmly with both hands on opposite sides of the wheel
- Keep one hand on the top of the steering wheel and another hand on the bottom of the steering wheel
- Hold the steering wheel loosely in the 10 o'clock and 2 o'clock positions
- Use one hand with a firm grip on the top of the steering wheel
Quote From Page 23 Of The CDL Manual:
Hold the steering wheel firmly with both hands. Your hands should be on opposite sides of the wheel. If you hit a curb or a pothole (chuckhole), the wheel could pull away from your hands unless you have a firm hold.
- About 115 psi
- About 90 psi
- About 110 psi
- About 125 psi
Quote From Page 66 Of The CDL Manual:
Check air compressor governor cut-in and cut-out pressures: Pumping by the air compressor should start at about 100 psi and stop at about 125 psi. (Check manufacturer's specifications.) Run the engine at a fast idle. The air governor should cut out the air compressor at about the manufacturer's specified pressure. The air pressure shown by your gauge(s) will stop rising. With the engine idling, step on and off the brake to reduce the air tank pressure. The compressor should cut in at about the manufacturer's specified cut-in pressure. The pressure should begin to rise.
It is important to memorize the "cut in" and "cut out" levels for the air governor as well as the terminology.
Cut in: When the governor tells the air compressor to start pumping air into the air tanks. This should occur when air pressure falls to about 100 psi.
Cut out: When the governor tells the air compressor to stop pumping air into the air tanks. This should occur when the air pressure has risen to about 125 psi.
- Identification number
- Hazardous class or division number
- Proper shipping name
- The amount of "outage" the product has (if a liquid product)
Quote From Page 92 Of The CDL Manual:
The basic shipping description of a hazardous material on a shipping paper must include the (1) identification number (preceded by the letters UN or NA); (2) DOT proper shipping name; (3) hazardous class or division number of a product (must include subsidiary hazard class when required); and (4) packing group for a product in a roman numeric pattern (may precede with the letters PG).
While it is solely the shippers responsibility to provide you with proper shipping papers, you must be certain all shipping papers are correct before leaving their facility. If there are any issues with the paperwork along your trip (DOT inspections, etc) it will cost you time and you can possibly be ticketed.
- Tells you how much pressure is in the air tanks
- Let's you know when air pressure in the tanks are too low
- Shows how much air pressure you are applying to the brakes
- Application pressure gauges must be installed on all commercial vehicles
Quote From Page 64 Of The CDL Manual:
Application Pressure Gauge - This gauge shows how much air pressure you are applying to the brakes. (This gauge is not on all vehicles.) Increasing application pressure to hold the same speed means the brakes are fading. You should slow down and use a lower gear. The need for increased pressure also can be caused by brakes out of adjustment, air leaks or mechanical problems.
- To ensure drivers wouldn't push themselves too far
- To require drivers to keep an updated log showing all of their working and resting hours
- So that carriers can't force drivers to drive beyond their limits
- To regulate the maximum amount of time drivers can spend resting between driving shifts
Quote From Page 0 Of The CDL Manual:
What Are Hours Of Service Regulations?
HOS regulations are rules issued by the Federal Motor Carrier Safety Administration (FMCSA) which is a division within the Department of Transportation (DOT). The regulations limit the number of daily and weekly hours which can be spent driving and working. They also regulate the minimum amount of time drivers must spend resting between driving shifts. Drivers are required to keep an updated log showing all of their working and resting hours.
Why Do HOS Regulations Exist?
The purpose of HOS regulations is to reduce accidents caused by driver fatigue. Many drivers don't like being told when they can and can't drive, but as you can see in Figure 13-1 below, the risk of an accident is directly related to how many hours a driver has been behind the wheel. HOS regulations were designed so that drivers wouldn't push themselves too far and also so that carriers can't force drivers to drive beyond their limits.
The required resting periods are minimum requirements, not maximum requirements. The same can be said about working hours. Bottom line, if you're too tired to drive, don't drive!
- To set cargo on top of.
- To fill empty space between cargo.
- To make pallets.
- To reinforce blocking.
Quote From Page 2 Of The CDL Manual:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- Secure roll against rear doors.
- All of these are acceptable
- Wedges or chocks secured by some means in addition to friction.
- Secure blocking against rear doors.
Quote From Page 6 Of The CDL Manual:
Note: Chocks, Wedges, or Blocking Securing the Front or Rear Roll - Hold in place by some means in addition to friction so they cannot become unintentionally unfastened or loose while the vehicle is in transit. This is often accomplished with nails.
Requirements for eyes crosswise: secure rearmost roll
Do not secure the rearmost roll with:
- Either the rear doors of the vehicle or intermodal container
- Or blocking held in place by those doors.
