Review Questions - Click On The Picture To Begin...
These Questions Are From The Illinois CDL Manual
- Not all hazardous material loads require placards
- Hazardous liquids can only be carried in a tanker truck
- Any amount of hazardous cargo requires a hazardous material license endorsement
- Hazardous material shipping papers must be kept in the glove box at all times
Quote From Page 49 Of The CDL Manual:
Not all vehicles carrying hazardous materials need to have placards.
- The yellow signs before curves and ramps are designated safe speeds
- 10mph under the posted speed limit is considered a safe speed
- Speeds of 55mph or below are considered safe speeds for maximum fuel mileage
- A predetermined speed for descending down a long or steep grade, which helps determine when brakes should be applied or released
Quote From Page 68 Of The CDL Manual:
Remember, the use of brakes on a long and/or steep downgrade is only a supplement to the braking effect of the engine. Once the vehicle is in the proper low gear, the following is the proper braking technique:
- 1. Apply the brakes just hard enough to feel a definite slowdown.
- 2. When your speed has been reduced to approximately 5 mph below your "safe" speed, release the brakes. (This brake application should last about 3 seconds.)
- 3. When your speed has increased to your "safe" speed, repeat steps 1 and 2.
- Removable tanks attached to a chassis
- Any of these are considered Cargo Tanks
- A series of portable containers
- Bulk packaging permanently attached to a vehicle
Quote From Page 100 Of The CDL Manual:
Cargo tanks are bulk packagings permanently attached to a vehicle. Cargo tanks remain on the vehicle when you load and unload them.
- None of these answers are correct
- You are not allowed to drive after you've been on duty 70 hours in the previous 8 consecutive days
- You are not allowed to be on duty more than 70 hours within the previous 8 days
- You must have taken at least 70 hours off during the previous 8 days in order to drive legally
Quote From Page 0 Of The CDL Manual:
The 8 day / 70 hour limit:
If your company does operate vehicles every day of the week, your employer may assign you to the 70-hour/8-day schedule. This means that you are not allowed to drive after you've been on duty 70 hours in any 8 consecutive days. Once you reach the 70 hour limit, you will not be able to drive again until you have dropped below 70 hours for an 8 consecutive day period. You may do other work, but you cannot do any more driving until you get below the limit. Any other hours you work, whether they are for a motor carrier or someone else, must be added to the total.
The 8 day / 70hr limit will restrict how much time you're allowed to be on duty during an 8 day period. So if you take a 10 hour break to reset your 11 and 14 hour clocks, but have been on duty / driving for 65 hours in an 8 day period, you will only be able to drive 5 hours.
We'll give you some more examples later on in the program. This can be a little difficult to understand, but try to understand the differences between the 11hr, 14hr, and 70hr clocks.
- A yellow banner on the front and back of the truck displaying the type of hazardous material on-board
- Diamond-shaped warning signs on all 4 sides of the vehicle
- An orange "HAZMAT Certified" window sticker on the passenger side of the windshield
- A red square warning sign on all 4 sides of the vehicle
Quote From Page 86 Of The CDL Manual:
The regulations require vehicles transporting certain types or quantities of hazardous materials to display diamond-shaped, square-on-point, warning signs called placards.
- There will be rust visible in a particular spot
- A loose fitting may cause a leak
- There will be carbon soot collected into one area of the pipe
- All of these can be signs of an exhaust leak
Quote From Page 119 Of The CDL Manual:
- Check system for damage and signs of leaks such as rust or carbon soot.
- System should be connected tightly and mounted securely.
While inspecting the exhaust system, tell the examiner:
"The exhaust should be properly mounted and secured, no loose clamps, no signs of leaks such as rust or soot, and it must contain no holes, cracks, or dents."
- National Response Center
- Federal HAZMAT Response Corp.
- Poison Control
Quote From Page 104 Of The CDL Manual:
The National Response Center helps coordinate emergency response to chemical hazards. It is a resource to the local police and firefighters. The center maintains a 24-hour, toll-free line. You or your employer must call the center when any of the following occur as a direct result of a hazardous materials incident per 171.15, 171.16:
- No more than 2 psi
- No more than 3 psi
- No more than 5 psi
- No more than 4 psi
Quote From Page 117 Of The CDL Manual:
With the engine running, build the air pressure to governed cut-out (100-125 psi). Shut off the engine, turn the electrical power on, chock your wheels, if necessary, release the tractor protection valve and parking brake (push in), fully apply the foot brake and hold it for one minute. Check the air gauge to see if the air pressure drops more than 3 pounds in 1 minute (single vehicle) or 4 pounds in 1 minute (combination vehicle) with brake applied. When brake is unapplied, air pressure drops more than 2 pounds in 1 minute with a single vehicle and 3 pounds in 1 minute in a combination vehicle.
Be sure to memorize how much air loss is acceptable when the service brakes are applied and not applied.
- All of these answers are correct
- More than two cargo carrying vehicles are in the combination
- The other vehicle in the combination contains any substances, explosive, n.o.s., Division 1.1A (explosive) material (initiating explosive)
- Any fuller trailer in the combination has a wheel base of less than 184 inches
Quote From Page 97 Of The CDL Manual:
Division 1.1 or 1.2 (explosive) materials may not be loaded into or carried on any vehicle or a combination of vehicles if:
-More than two cargo carrying vehicles are in the combination,
-Any fuller trailer in the combination has a wheel base of less than 184 inches,
-Any vehicle in the combination is a cargo tank required to be marked or placarded under §177.823, or
-The other vehicle in the combination contains any:
- substances, explosive, n.o.s., Division 1.1A (explosive) material (initiating explosive),
-Packages of Class 7 (radioactive) materials bearing "Yellow III" labels,
- Division 2.3, Hazard Zone A or Hazard Zone B materials or Division 6.1, PG I, - - Hazard Zone A materials, or
- Hazardous materials in a portable tank or a DOT specification 106 A or 110A tank.
- To save room in the tank, most shippers of liquid food products prefer to forgo baffles so more product can be loaded
- Sanitation regulations forbid the use of baffles because of the difficulty in cleaning the inside of the tank
- Food products are generally light enough that the entire tank can be filled, thus, limiting any liquid surge
- Food grade tankers are required to be fitted with baffles or bulkheads
Quote From Page 84 Of The CDL Manual:
Sanitation regulations forbid the use of baffles because of the difficulty in cleaning the inside of the tank.
Anytime you see a food grade tanker, it is safe to assume there are no baffles installed. Not only is that important for you to know when pulling a food grade tanker, but you can also drive differently around other vehicles that are pulling food grade tankers (give them more room).
