The Alabama CDL handbook consists of thirteen sections, containing everything needed to understand CDL license classifications, medical disqualification, and more.

HazMat: overview of regulatory requirements governing transport of hazardous materials, loading and labeling bulk containers for hazardous materials transport, responsibility of the driver throughout each leg of transport, guidelines for safe parking and communication for hazardous materials transport, emergency response procedures for hazardous materials spills and leaks, and safe methods for loading and unloading hazardous materials.

Includes identification and location of each item to inspect, including those items that must be touched to identify their presence and those items that must be verbally confirmed.
Basic Vehicle Control Skills Test: the basic skills test includes three exercises. Each exercise will be rated according to the scoring criteria. Exercises included: straight-line backing exercise; offset-backing exercise to both sides; parallel parking in both conventional and driver-side configurations.
On-Road Driving Test: the on-road driving test assesses the candidate’s ability to navigate various situations such as turning corners, navigating intersections, railroad crossings, lane changes, grades, and other aspects associated with normal traffic flow. The examiner will evaluate the candidate’s actions in traffic.

Using the Manual to Prepare for the Alabama CDL Tests

A manual of 160 pages can seem overwhelming unless you have a strategy. To prepare for your test, follow this plan:

Review the introductory material first. This will help you figure out which of the 13 chapters relate directly to your chosen license class or endorsements. There is little reason to study HazMat if you are pursuing a Class B license without HazMat.
Study every chapter required for your license class and endorsements. Then take practice tests prior to moving on. ALEA uses the federal 80% passing percentage on all written tests. It is worth spending more time reviewing Driving Safely and Vehicle Inspection. These chapters apply to every license class and contain more than half of the total number of pages in this manual.
Use our free Alabama CDL practice tests multiple times until you score 90% or better consistently before making an appointment for your test.
Once you are able to score 90% or better consistently on our free Alabama CDL practice tests, schedule an appointment at one of the ALEA driver license offices that offers commercial testing services.

Practice tests serve as proof of learning. When you feel comfortable with our practice tests, you can rely on them because they mimic the format and difficulty of the real ALEA exams.

Alabama CDL Testing Requirements

Some features make Alabama’s commercial learner’s permit process different from most other states. ALEA (not a state Department of Motor Vehicles) issues CDLs via its Driver License Division. Appointments for both knowledge and skills tests are scheduled online at ALEA.gov. An Alabama commercial learner’s permit (CLP) is valid for 360 days but cannot be renewed.

Therefore, when your permit expires, you will have to take all written tests again and pay for a new CLP. Before applying for a CLP, you must possess a valid Alabama Class D driver’s license. Military personnel may receive a military skills waiver if they currently possess or held a military driver license with a qualifying transportation occupation specialty within the past twelve months. See our Alabama CDL practice test page for more information regarding the complete process of obtaining an Alabama CDL.

FAQs

How many pages is the Alabama CDL handbook?

As of the latest version, it is 160 pages long. You do not have to read every page — the license class and endorsements you have applied for will tell you which chapters are relevant to your needs.

Does the Alabama CDL manual differ from the federal CDL manual?

While ALEA utilizes the AAMVA model curriculum common among many states, it publishes its own version with state-specific procedures, testing locations, and contact information. All knowledge tests are evaluated against the ALEA-issued handbook.

How often does ALEA update the Alabama CDL handbook?

ALEA updates the manual PDF periodically — the underlying content was last revised in July 2017, and ALEA updated its manual PDF distribution most recently in late 2023. Verify with ALEA.gov to ensure you are referring to the latest version before relying on older copies.

What language(s) is the Alabama CDL handbook available in?

ALEA has published its handbook, entitled “Commercial Driver License Manual,” solely in English. Visit the ALEA driver license webpage to inquire if alternative language versions exist.

Must I read the entire Alabama CDL manual to pass my test?

No. The introduction outlines which chapters are applicable to your license class and endorsements. Those seeking Class B licensure without endorsements would therefore bypass many specialty chapters contained herein.

Are the Alabama CDL handbook and Alabama driver’s manual identical?

No — they are separate publications by different ALEA divisions. The commercial driver’s manual covers safe operation of commercial motor vehicles (CDL), while the standard driver’s manual concerns operation of non-commercial standard Class D vehicles.

What are the key differences between studying this handbook and practicing with our Alabama CDL practice tests?

This handbook represents the original source material — every test question is drawn from this resource. Our practice tests are a verification method that confirms whether you have effectively absorbed the material; they are formatted similarly to actual ALEA exams; and they provide opportunities to fill in potential knowledge gaps before sitting for your actual ALEA test.
