- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.

Void Filler:
Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- A certified mechanic may do the vehicle inspection instead of the driver
- Any CDL holder can deem a vehicle safe to operate as long as they sign off on the daily inspection report
- While it's important to perform daily vehicle inspections, there are no federal regulations requiring inspections be done on each day the vehicle is driven
- The driver is always responsible for completing their own daily inspections
Quote From Page 13 Of The CDL Manual:
The most important aspect of traffic safety for yourself and others who share the road with you is that you personally inspect your vehicle. A vehicle defect found during an inspection could save you problems later. You could have a breakdown on the road that will cost you time and money, or even worse, an accident caused by the defect.
Federal and state laws require that drivers inspect their vehicles. Federal and state inspectors also may inspect your vehicles. If they judge a vehicle to be unsafe, they will put it "out of service" until it is repaired.
TruckingTruth's Advice:
A daily vehicle inspection is crucially important. Many drivers will forgo an inspection if they are pressed for time, but this is extremely dangerous. You are not safe to drive until you've done an inspection of your vehicle.

Quote From Page 22 Of The CDL Manual:
If the vehicle has hydraulic brakes, pump the brake pedal three times. Then apply firm pressure to the pedal and hold for five seconds. The pedal should not move. If it does, there may be a leak or other problem. Get it fixed before driving.
- When the trailer is empty
- When the trailer is loaded to half of its maximum weight
- All trailers, regardless of weight or cargo placement, have an equal chance of jackknifing
- When the trailer is fully loaded to maximum weight
Quote From Page 71 Of The CDL Manual:
When the wheels of a trailer lock up, the trailer will tend to swing around. This is more likely to happen when the trailer is empty or lightly loaded. This type of jackknife is often called a "trailer jackknife"
- Increased air pressure
- Wheel lock-ups
- Pulling to one side or the other
- Lack of braking power
Quote From Page 37 Of The CDL Manual:
When driving in heavy rain or deep standing water, your brakes will get wet. Water in the brakes can cause the brakes to be weak, to apply unevenly or to grab. This can cause lack of braking power, wheel lock-ups, pulling to one side or the other, and jackknife if you pull a trailer.
TruckingTruth's Advice:
During cold weather, wet brakes can also cause brake pads to freeze to the brake drums. Before parking, you can ride the brakes a bit to heat them up slightly and dry them out.

Quote From Page 93 Of The CDL Manual:
Shipper's Certification When the shipper packages hazardous materials, he/she certifies that the package has been prepared according to the rules. The signed shipper's certification appears on the original shipping paper. The only exceptions are when a shipper is a private carrier transporting their own product, and when the package is provided by the carrier (e.g., a cargo tank). Unless a package is clearly unsafe or does not comply with the HMR, you may accept the shipper's certification concerning proper packaging. Some carriers have additional rules about transporting hazardous products. Follow your employer's rules when accepting shipments.
Shippers print required markings directly on the package, an attached label or tag. An important package marking is the name of the hazardous material. It is the same name as the one on the shipping paper. When required, the shipper will put the following on the package:
- Name and address of shipper or consignee.
- Hazardous material's shipping name and ID number.
- Required labels.
- ID number on bulk packages.
- Windshield
- Front axle
- Steering System
- Air tank
Quote From Page 20 Of The CDL Manual:
Font of Vehicle
- Condition of front axle.
- Condition of steering system.
- No loose, worn, bent, damaged or missing parts.
- Must grab steering mechanism to test for looseness.
- Condition of windshield.
- Check for damage and clean if dirty.
- Check windshield wiper arms for proper spring tension.
- Check wiper blades for damage, "stiff" rubber and securement.
- Seals placed on rear doors of box trailers or output devices on tankers to prevent hazardous materials from leaking
- Stickers placed on shipping papers that identify the hazard class of the cargo
- Small stickers placed on the drivers and passengers side window showing the driver has a hazardous materials endorsement
- Signs put on the outside of a vehicle that identify the hazard class of the cargo
Quote From Page 89 Of The CDL Manual:
Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle that identify the hazard class of the cargo. A placarded vehicle must have at least four identical placards. They are put on the front, rear and both sides of the vehicle. Placards must be readable from all four directions. They are 10 3/4-inches square, square-on-point, in a diamond shape. Cargo tanks and other bulk packaging display the ID number of their contents on placards, or orange panels or white square-on-point displays that are the same size as placards, and placed near the placards.
TruckingTruth's Advice:
Always be sure to ask for an extra placard or two when leaving a shipper in case a placard is blown off the truck during transit.

Quote From Page 31 Of The CDL Manual:
One good rule for how much space you should keep in front of you is at least 1 second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead. In a 60-foot rig, you will need 6 seconds. Over 40 mph, you would need 5 seconds for a 40-foot vehicle and 7 seconds for a 60-foot vehicle.
TruckingTruth's Advice:
These types of questions are very common during the written exam and can be a bit confusing as they change the size of the vehicle as well as their speeds. But it's rather simple to calculate: For each 10 feet of vehicle, you need 1 second of following distance. Anything over 40mph, simply add 1 second to your total. Be 100% confident about this formula before taking the written exam as this will probably show up.

Quote From Page 8 Of The CDL Manual:
A conviction for violation of an out-of-service order results in disqualification for a minimum six months
TruckingTruth's Advice:
The department of transportation may put drivers out-of-service for several reasons, including equipment problems, hours of service violations, alcohol violations, and any other reason they deem fit. Do not violate the out-of-service order as that is a very serious offense and could ruin your career.
