Everything You Need To Know About the CDL Test
If you’re interested in operating a commercial motor vehicle (CMV), you need to obtain a commercial driver’s license (CDL). Every American state has different rules regarding driving tests, but the basic regulations are usually the same.
DoNotPay can help you ace your CDL writing test and bring you one step closer to getting a driver’s license.
Commercial Driver’s License Test Explained
In most American states, you need to be 21 to take a CDL driving test. There are three vehicle classifications you can take the test for:
Taking a written DMV CDL test should be the first item on your driving test checklist. You need to pass it to get a commercial learner’s permit (CLP). The written tests in most states consist of three segments:
- General test
- Endorsement tests
- Air brakes test
A Guide to Endorsement Tests
There are several types of endorsement tests. You should pass the ones required for the commercial motor vehicle you want to operate:
- H endorsement—vehicles that contain hazardous materials
- N endorsement—tank vehicles that transport liquids and gasses
- P endorsement—vehicles for 16 or more people
- S endorsement—school busses (a P endorsement is also obligatory)
- T endorsement—double or triple trailers
- X endorsement—tank vehicles and vehicles transporting hazardous materials
Drivers with certain restrictions can’t operate some types of commercial motor vehicles. While every state has different laws, there are seven basic restriction codes—E, L, M, N, O, V, and Z. Some states might have additional codes. You should check the restrictions of the state in which you want to drive.
Drivers who perform a skill test with an automatic transmission will be issued an E restriction. They won’t be able to operate a vehicle with a manual transmission.
An L restriction disallows the operation of commercial vehicles with air brakes. You’ll get an L restriction in your license if you don’t:
- Pass the air brakes test
- Take the skills test on a vehicle with an air brake system
- Check the air brakes work properly
- Identify the components of the air brakes system
Drivers who have a CDL for Class A vehicles but get their P and S endorsements in a Class B vehicle will get an M restriction. Chauffeurs with an M restriction can drive only a school bus or Class B or C passenger vehicles.
If you have an N restriction on your CDL, you can operate a school bus and Class C passenger vehicles. Chauffeurs with a Class B license will get an N restriction if they pass the P and S endorsement tests in Class C vehicles.
Chauffeurs with an O restriction can’t operate a Class A vehicle that has a fifth-wheel connection. If you take the test in a Class A commercial vehicle without a fifth-wheel connection or with a pintle hook, you’ll get an O restriction.
Drivers with vision, seizure, diabetic, and hearing impairments will get a V restriction in their CDL. That’s why a medical exam is obligatory when obtaining a commercial driver’s license.
A Z restriction indicates that a chauffeur can’t operate a commercial motor vehicle with full air brakes.
Reasons To Prepare for the CDL Written Test
Commercial driving test fees can be pricey, especially if you take the test multiple times. CDL tests are usually challenging, and that’s why many people fail. Passing your written commercial driving license test on the first try is possible if you’re well-prepared for the exam.
Preparing for your CDL test will also help you feel more confident, which will make the exam less stressful. The sooner you obtain a learner’s permit, the sooner you’ll be allowed to take the road test and apply for commercial driving jobs.
Written CDL tests are important for road safety, which is crucial when transporting hazardous materials or large groups of passengers.
How Can You Prepare for Your Commercial Driving Test?
Prospective CMV drivers can prepare for the test by:
- Reading the state’s official manual—Every state has a different manual. You can head over to your local DMV and ask for a print version or find a PDF handbook on the Driving Tests website
- Signing up for a CDL training program—Your local DMV should organize classes that can help you prepare for the test. These programs are usually expensive, which is why not many people sign up
- Taking a few practice tests—Practice tests are the best way to prepare for any government exam, including CDL
