What is a Class B CDL?

A Class B CDL allows you to operate heavy single vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 26,000 pounds. Unlike a Class A CDL, which is required for tractor-trailers and heavy truck-trailer combinations, a Class B license is for vehicles not towing trailers heavier than 10,000 pounds.

Differences Between CDL Classes

CDL Type	Vehicle Type	GVWR Requirements	Trailer Restrictions	Common Jobs
Class A	Tractor-trailers, semi-trucks, heavy truck-trailer combos	26,001+ lbs (trailer over 10,000 lbs)	No restriction	Over-the-road (OTR) trucking, freight hauling
Class B	Straight trucks, box trucks, buses, dump trucks	26,001+ lbs	Trailer must be under 10,000 lbs	Local delivery, public transit, construction
Class C	Passenger vans, hazmat vehicles	Less than 26,001 lbs	No large trailers	Chauffeurs, hazardous material transport

While Class A licenses allow for the operation of combined truck and trailer units, Class B is for single heavy vehicles. If you’re not towing a large trailer but still operating a vehicle over 26,000 pounds, Class B is the appropriate license.

How to Get a Class B CDL

Step 1: Earn Your Commercial Learner’s Permit (CLP)

This involves passing a knowledge test and obtaining medical clearance. You must hold the CLP for at least 14 days before taking the CDL skills test. To qualify, you’ll need:

A valid driver’s license
A clean 10-year driving history
Medical certification from an FMCSA-approved examiner

Step 2: Complete CDL Training

CDL training combines classroom instruction and behind-the-wheel training. Programs typically last 2 to 6 weeks and include:

Classroom instruction on CDL rules and safety
Behind-the-wheel training in a Class B vehicle
Practice tests to prepare for the CDL exam

Step 3: Pass the CDL Skills Test

Once you’ve completed training, you’ll take the CDL skills test, which includes:

Pre-trip inspection – Demonstrate knowledge of vehicle safety features
Basic control test – Show skill in parking, backing, and maneuvering
Road test – Prove you can safely operate the vehicle on public roads

How Long Does ELDT Take for a Class B License?

The timeline varies based on your training provider and schedule:

Full-time students can complete ELDT in 3–6 weeks
Part-time students may take 2–3 months
Online theory can be completed in as little as a week, while BTW schedules vary

Who Provides ELDT Training?

Only providers listed on the FMCSA’s Training Provider Registry (TPR) can offer valid ELDT. These include:

Private truck driving schools

Is ELDT Recommended for Experienced Drivers Upgrading or Reentering the Industry?

Yes. Even experienced drivers returning after a lapse or upgrading their licenses are required to complete ELDT. It’s also an excellent refresher for staying up to date with compliance and equipment standards.

What Can Disqualify You from Getting a Class B CDL?

Check your state’s CDL qualifications before applying. Common disqualifications include:

DUI or drug-related offenses
Felony convictions involving a commercial vehicle
Serious traffic violations (e.g., reckless driving)
Suspended or revoked personal driver’s license

Always verify your eligibility with your state’s DMV or licensing agency before beginning the process.
