These Questions Are From The Illinois CDL Manual
- A series of portable containers
- Any of these are considered Cargo Tanks
- Bulk packaging permanently attached to a vehicle
- Removable tanks attached to a chassis
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.
- Coolant temperature
- Engine oil temperature
- All of these should read normally within seconds of starting the engine
- Engine oil pressure
Quote From Page 16 Of The CDL Manual:
Look at gauges:
- Oil pressure - Should come up to normal within seconds after engine is started.
- Ammeter and/or voltmeter - Should be in normal range(s).
- Coolant temperature - Should begin gradual rise to normal operating range.
- Engine oil temperature - Should begin gradual rise to normal operating range.
- Warning lights and buzzers - Oil, coolant, charging circuit warning lights should go out right away.
- 4 seconds
- 3 seconds
- 5 seconds
- 6 seconds
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.
These types of questions almost always show up during the written exam. Be 100% confident you understand the following distance formula.
Remember: For every 10ft of you vehicles length, you need 1 second of following distance. Anything over 40mph, add 1 second to your total.
It is very important that you understand this and can calculate proper following distance for any vehicle length and any speed.
Quote From Page 4 Of The CDL Manual:
There are seven special CDL endorsements and one restriction that require testing. In addition, drivers who do not pass the air brake portion of the exams are restricted to driving vehicles without air brakes.
The endorsements are:
- 1. Charter Bus (C)
- 2. Combination Tank and Hazardous Materials (X)
- 3. Double/Triple Trailers (T)
- 4. Passenger Vehicles (P)
- 5. School Bus Endorsement (S)
- 6. Tank Vehicles (N)
- 7. Vehicles Carrying Hazardous Materials (H)
1. Vehicle Without Air Brakes (L-Restriction)
We highly recommend that everyone get all endorsements available because:
- You don't want to restrict your opportunities
- The tests are fairly quick, simple, and inexpensive
- You're already going through the process of learning the materials anyhow
So make sure you get all of the endorsements.
Is the below example a completed 34 hour restart?
- Yes, the restart has been completed
- None of these answers are correct
- No, the driver didn't complete two rest periods between 1:00 a.m. and 5:00 a.m.
- No, the driver didn't spend enough time off duty to complete the restart
Quote From Page 0 Of The CDL Manual:
Explanation - 34 Hour Restart: This example shows a 34 hour restart which is incomplete. While the driver took a total of 34 hours off duty from 4:00 a.m. on Day 1 until 4:00 p.m. on Day 2 (total of 36 hours off duty) the driver still did not meet the requirements. Two rest periods must be taken between the hours of 1:00 a.m. to 5:00 a.m. and in this example, only one rest period during those hours were completed (Day 2). This driver is not necessarily in violation of any rules, but he/she still must count back the previous 8 days when calculating the 70 hour limit as the 34 hour break did not reset the 70 hour limit.
- Steep drop-off next to the roadway
- Brake failure
- A tire blows out
- Steering malfunction
Quote From Page 42 Of The CDL Manual:
Vehicle emergencies occur when tires, brakes or other critical parts fail.
Understand the difference between the following:
- Traffic Hazard: Any road condition or other road user (driver, bicyclist, pedestrian) that is a possible danger.
- Traffic Emergency: When two vehicles are about to collide.
- Vehicle Emergency: When tires, brakes or other critical parts fail.
- You should never assist the injured until authorities have arrived
- Assist the injured immediately
- Assist the injured only after you have protected the area and notified authorities
- Assist the injured after you have protected the area, but before you have notified authorities
Quote From Page 45 Of The CDL Manual:
If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties:
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary.
- Stop heavy bleeding by applying direct pressure to the wound.
- Keep the injured person warm.
If you are the first one on the scene of a serious accident, you may want to help the injured right away. But make sure you secure the scene of the accident first to avoid any additional collisions. You should then notify the authorities before attempting to assist an injured person. Make sure you memorize the order of recommended accident procedures:
1. Protect the area
2. Notify authorities
3. Assist the injured
On what day and time does a 14 hour rule violation occur?
- There is no 14 hour rule violation
- Day 2 at 4:00 p.m.
- Day 2 at 5:00 a.m.
- Day 2 at 2:00 a.m.
Quote From Page 0 Of The CDL Manual:
Violations: There is an 11 hour rule violation from 5:00 a.m. - 7:00 a.m. on Day 2.
Explanation - 11 Hour Limit: After 10 hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had 3 hours remaining, and exceeded the limit, by 2 hours, starting at 5:00 a.m. Then, because the driver accumulated at least 10 hours of rest using a combination of at least 8 consecutive hours in a sleeper berth and another break of at least 2 consecutive hours (in this case, 8), he or she was eligible for the split sleeper berth provision. This moves the calculation point to the end of the first of the two periods of rest, or 2:00 a.m. on Day 2. Between 2:00 a.m. and 3:00 p.m., the driver had 5 hours of driving, so at 3:00 p.m. on Day 2 there were 6 hours remaining, which the driver used by 9:00 p.m. Because the driver then took at least 2 consecutive hours off duty, he or she accumulated another 10 hours of rest in two separate, qualifying periods totaling 10 hours. This moves the calculation point again, to 3:00 p.m. on Day 2, and at 11:00 p.m. on Day 2 the driver has 5 hours of driving time remaining.
Explanation - 30 Minute Break: On Day 1, the driver required a 30 minute break at 6:00 p.m. in order to continue driving. But since the driver went into the sleeper berth and stayed there for 8 hours, the requirement was no longer needed. On Day 2, the driver never stayed on duty long enough to 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 accumulates 8 hours of driving time by 6:00 p.m. before entering the sleeper berth. Because any sleeper berth period of at least 8 (but less than 10) consecutive hours is excluded from the 14 hour calculation, the driver accumulated just 13 hours by 7:00 a.m. on Day 2. The driver then met the requirements for the split sleeper berth provision, so the calculation point moves to the end of the first qualifying break, or 2:00 a.m. on Day 2. Starting from there, the driver accumulated 11 hours by 9:00 p.m. on Day 2. The driver again met the requirements for the split sleeper berth provision by getting 2 hours of rest, so the calculation point moves to 3:00 p.m. and the driver remains in compliance.
- All of these can help reduce the chance of a truck rollover
- Slow down to a safe speed before going into a turn
- Look far enough down the road to avoid being surprised and having to make a sudden lane change
- At night, drive slow enough to see obstacles with your headlights before it is \ too late to change lanes or stop gently
Quote From Page 70 Of The CDL Manual:
Steer gently and smoothly when pulling trailers. If you make a sudden movement with your steering wheel, you could tip over. Follow far enough behind other vehicles (at least 1 second for each 10 feet of your vehicle length, plus another second if going over 40 mph). Look far enough down the road to avoid being surprised and having
- Total weight of a powered unit
- Total weight of a single vehicle plus its load
- Weight transmitted to the ground by one axle or one set of axles
- Maximum GCW specified by the manufacturer for a specific combination of vehicles plus its load
Quote From Page 52 Of The CDL Manual:
You are responsible for not being overloaded. Following are definitions of weights:
- Gross vehicle weight (GVW): Total weight of a single vehicle plus its load.
- Gross combination weight (GCW): Total weight of a powered unit plus trailer(s) plus the cargo.
- Gross combination weight rating (GCWR): Maximum GCW specified by the manufacturer for a specific combination of vehicles plus its load.
- Axle weight: Weight transmitted to the ground by one axle or one set of axles.
- Tire load: Maximum safe weight a tire can carry at a specified pressure. This rating is stated on the side of each tire.
- Suspension systems: Suspension systems have a manufacturer's weight capacity rating.
- Coupling device capacity: Coupling devices are rated for the maximum weight they can pull and/or carry.
