Non-commercial Class A and B - the licence for a big RV or trailer

If you have just bought a large trailer or a motorhome, the question is almost always the same one: does the licence in my wallet already cover this? For most people it does. This page gives the actual thresholds rather than a rounded-off version of them, because the rounding is where people get it wrong in both directions.

Do you actually need one?

Start here, because the answer is often no. A basic Class C licence already lets you drive:

• a 2-axle vehicle rated 26,000 lbs GVWR or less, or a 3-axle vehicle weighing 6,000 lbs gross or less
• any housecar 40 feet or under - which is the large majority of motorhomes on the road
• a single vehicle rated 10,000 lbs GVWR or less, including a tow dolly if you use one

And if your tow vehicle weighs 4,000 lbs or more unladen, a Class C also lets you tow a trailer coach not exceeding 9,000 lbs gross, or a trailer coach or fifth-wheel travel trailer under 10,000 lbs GVWR, so long as the towing is not for compensation.

Read those numbers as ratings, not impressions. A trailer that feels enormous may sit under the threshold, and a compact one loaded heavy may not. The figure that matters is the GVWR on the plate.

Non-commercial Class A

You need a non-commercial Class A to tow, not for hire:

• a conventional travel trailer over 10,000 lbs GVWR, or
• a fifth-wheel travel trailer over 15,000 lbs

Those two numbers are different, and that is the single most misquoted thing about this licence. “Over 10,000 pounds” is correct for a conventional travel trailer and wrong for a fifth-wheel, which gets an extra 5,000 lbs of headroom before Class A is required. If you have been told you need a Class A for a 12,000 lb fifth-wheel, you have been told wrong - see the endorsement below.

A non-commercial Class A also covers anything a Class C covers.

Non-commercial Class B (the 45-foot housecar)

This one is about length, not weight. A housecar over 40 feet but not over 45 feet needs a non-commercial Class B with the housecar endorsement. At 40 feet or under, your Class C is enough; over 45 feet is outside what this licence authorises.

Class B carries a requirement the others do not: a Physician’s Health Report (DL 546A), signed by your physician, reviewed and approved by the DMV before the licence is issued, and then renewed every two years.

The fifth-wheel endorsement

Between the Class C limit and the Class A threshold sits a band that trips people up, and it is the single most valuable thing on this page. A fifth-wheel recreational trailer over 10,000 lbs but not over 15,000 lbs GVWR, not used for hire, needs a fifth-wheel recreational trailer endorsement added to the Class C licence you already hold - not a Class A. The DMV is explicit that the endorsement is not required if you already hold a commercial or non-commercial Class A.

Owners generally call it “Restriction 41”, after the code that appears on the licence. That is the name you will see in RV forums rather than in the DMV’s own handbook, which calls it the recreational trailer endorsement - so if you are searching for one term and finding the other, they are the same thing.

Why it matters is what the endorsement does not require. To add it you:

• complete a DL 44 - and there is no fee unless your licence expires within six months
• pass the Recreational Vehicles and Non-commercial Class A Trailers law test
• pass the basic Class C law test, unless you renewed your Class C within the last 12 months
• pass a vision test

And then the part that separates this from the Class A route entirely: you are not required to submit a health questionnaire or physician’s health report, and you are not required to take a pre-trip, skills, or driving test. The Class A route requires all of those. Same trailer, same band - a different licence path that is free, testable in one visit, and does not involve bringing the rig to a drive test.

If your fifth-wheel is in that band and you have been steered toward a non-commercial Class A, this is the distinction worth taking back to the counter.

Non-commercial is not commercial

The classes share letters with the commercial ones and are routinely confused with them. The dividing line is what the vehicle is used for, not how big it is.

Non-commercial A and B are for personal use - your own RV, your own trailer, explicitly not used for hire. The moment the same vehicle is moved for compensation, you are in commercial territory, which means federal Entry-Level Driver Training, a DOT medical certificate and a different set of tests. That is the CDL guide, not this page.
