CDL Endorsements Practice Test
Doubles and Triples Endorsement 
Tank Endorsement 
Hazardous MaterialThe CDL test is taken at your local DMV. It consists of two parts: the Knowledge test and the Skills test. The Knowledge test is a multiple-choice written exam and the Skills test consists of 3 segments (vehicle inspection, basic control skills, and road test).
You must pass the Knowledge tests before taking the Skills test. There are 8 Knowledge tests:
- General Knowledge (required for everyone)
- Air Brakes (required to drive vehicles with air brakes)
- Six Endorsement Tests
○ P: Passenger Transport (requires both a Knowledge and a Skills test)
○ X: Tank Vehicle/Hazardous Materials Combination (required to drive a combination or class A vehicle; requires a Knowledge test and the TSA Threat Assessment)
○ H: Hazardous Material (required to transport hazardous materials; requires a Knowledge test and the TSA Threat Assessment)
○ N: Tank Vehicles (required to transport liquids or gases in bulk; requires a Knowledge test)
○ T: Double/Triples Trailers (required if driving a vehicle that pulls double or triple trailers, requires a Knowledge test)
○ S: School Bus (requires both a Knowledge and a Skills test)
Everyone is required to take the “General” Knowledge test and depending on the vehicle to be driven, may be required to take additional Endorsement tests and/or the Air Brakes test. If you fail the Air Brakes Knowledge test or take the Skills test using a vehicle without air brakes, your CDL will have a restriction mark that tells others that you cannot drive vehicles with air brakes.
For the Hazardous Material endorsement, you will be required to submit your fingerprints and undergo a background check. You will not be able to get a Hazardous Material endorsement if
● you are not a lawful permanent resident of the U.S.
● you renounce your U.S. citizenship
● you have been convicted of certain felonies
● you have been adjudicated as a mental defective or committed to a mental institution
● U.S. Transportation Security Administration considers you a security threat
CDL Road Test
You must take the Skills test using the vehicle type you want to be licensed to drive. During the Skills test, you will be asked to do a pre-trip inspection as well as drive on the road.
To pass the road test portion of the CDL driving performance evaluation (DPE), you must make no more than 30 and no critical driving errors, resulting in an automatic failure.
The entire road test must be conducted in the English language, pursuant to CFR, Title 49 §§391.11(b) (2) and 383.133(c)(5).
If you communicate in a language other than English or fail to comprehend instructions given to you in English, during the skills tests (vehicle inspection, basic control skills, and road test) you will receive a verbal warning for the first 2 offenses committed on the same test date. Upon the third offense committed on the same test date, the test will end as an automatic failure.
Who Needs a CDL?
Anyone that wants to drive commercial motor vehicles (CMV) in interstate, intrastate, or foreign commerce needs a Commercial Driver’s License. A CMV is a vehicle that
- Has a gross vehicle weight rating (GVWR) of 26,001 pounds or more
- Designed to carry multiple passengers (including the driver) (check with your local DMV as the number of passengers varies from state to state)
- Transports hazardous materials that requires placards
- Tows any vehicle with a GVWR of 10,001 pounds or more
*GVWR is the gross vehicle weight rating; it is the maximum loaded weight of a single vehicle as stated by the manufacturer.
How to Get a Commercial Learner’s Permit (CLP)
You can get a Commercial Learner’s Permit (CLP) that allows you to drive a specific vehicle as long as there is another driver in the vehicle with you that has a CDL of equal or higher class and proper endorsements. To get a CLP, you must be at least 18 years old and have a valid non-commercial driver’s license.
The CLP is valid for 180 days and can be renewed for another 180 days as long as the CLP expiration date is less than 1 year from the initial application date. If the CLP contains a Tank (N) endorsement, the tank must be empty and purged of hazardous materials before a CLP holder can drive it. If the CLP contains a Passenger (P) and/or School Bus (S) endorsement, there must be no passengers in the vehicle before a CLP holder can drive it.
You must wait at least 14 days after CLP issuance before you can take the CDL Skills test.
How to Get a CDL?
To get a CDL, you must pass a state CDL test, hope you have tried our free CDL Practice Test. When applying for a CDL, you will need to specify whether you will be operating in intrastate or interstate commerce. In intrastate commerce, you only drive your vehicle WITHIN a single state. In interstate commerce, you may drive your vehicle across state lines as well as cross into a foreign country.
You must also provide a Medical Examination Report (MER) and a Medical Examiner’s Certificate Form (MEC) dated within the last 2 years. You will be required to provide an MER and MEC every 2 years. Medical examinations must be performed by a medical examiner listed on the National Registry of Certified Medical Examiners.
Once you have a CDL, you are required to return any non-CDL licenses back to the state. You can only ever have one CDL, so if you have a CDL from another state, you need to return that as well.
When applying for a job, you must disclose all driving jobs you have had in the last 10 years. You must notify your employer and the DMV within 30 days of any traffic violation convictions (except parking) regardless of the type of vehicle you were driving when you received the violation and regardless of the state you received the violation in. You must also notify your employer within 2 days if your license was suspended, revoked, or canceled.
You or your employer may be fined if you have more than one license or you drive a commercial vehicle without a CDL or with a suspended, revoked, or canceled CDL.
