What You Can and Cannot Drive With a Class B License

Class B lets you drive most vehicles you'll encounter on the road, but not all

A Class B driver's license permits you to operate single vehicles with a gross vehicle weight rating (GVWR) under 26,001 pounds. That covers your car, pickup truck, van, and most SUVs. It does not cover tractor-trailers, buses carrying passengers, or vehicles towing trailers over a certain weight. The exact restrictions depend on your state, because licensing rules vary by jurisdiction, but the core rule is consistent: Class B is for single vehicles under the weight threshold, with some exceptions for small trailers.

The weight limit matters more than you might think. Your vehicle's GVWR is not what it weighs empty—it is the maximum safe weight the manufacturer says it can carry, including passengers, cargo, and fuel. You can find this number on a sticker inside the driver's door jamb or in your owner's manual. Most passenger vehicles and light trucks stay well under 26,001 pounds, so you will rarely hit this ceiling unless you own a heavy-duty pickup or a large commercial van.

Key Takeaways

Class B covers cars, pickup trucks, vans, and most SUVs as long as the vehicle's GVWR is under 26,001 pounds.
You cannot drive a Class B vehicle if it is towing a trailer over a certain weight, which varies by state but is often 10,000 pounds or less.
Tractor-trailers, buses with passenger seats, and vehicles requiring a commercial driver's license are off-limits with Class B.
Some states allow Class B drivers to tow small utility trailers or boat trailers under specific weight limits without additional endorsements.
If you want to tow heavier trailers or drive larger vehicles, you will need a Class A license or a commercial driver's license (CDL).

Vehicles you can drive with Class B

The everyday vehicles most people own fall under Class B. This includes sedans, coupes, hatchbacks, station wagons, pickup trucks under the weight limit, minivans, and most crossovers and SUVs. Motorcycles are usually a separate endorsement, not part of Class B, so check your license to see if you have that added. Motorhomes and RVs under 26,001 pounds GVWR are also Class B in most states, though some states require a separate RV endorsement or restrict them based on length rather than weight.

The practical limit is straightforward: if you can find the GVWR on your vehicle and it is under 26,001 pounds, you can drive it with Class B. Most people never need to look this number up because their everyday vehicle is nowhere near the threshold. A full-size pickup truck typically sits around 6,000 to 8,000 pounds GVWR. A large SUV might reach 5,500 to 7,000 pounds. You would need something genuinely heavy—a commercial-grade truck or a large RV—to approach the limit.

Towing rules for Class B drivers

Towing is where Class B gets complicated, because the rules change by state. Most states allow Class B drivers to tow a trailer as long as the combined GVWR of the towing vehicle and trailer does not exceed a certain limit—often 26,001 pounds total. Some states use a different rule: they cap the trailer's GVWR alone at 10,000 pounds or less. A few states allow small utility trailers or boat trailers under 5,000 pounds without any restriction.

Before you tow anything, check your state's DMV website or handbook for the exact rule. The consequences of towing over the limit are real: you can be cited, your insurance may not cover an accident, and you are liable for any damage. If you want to tow a heavier trailer—say, a large horse trailer or a construction trailer—you will need to upgrade to a Class A license, which allows towing without the same restrictions.

Vehicles that require a higher license class

Class B does not cover commercial vehicles. A tractor-trailer (semi-truck) requires a Class A commercial driver's license (CDL). Any vehicle designed to carry 16 or more passengers (including the driver) requires a Class B CDL, not a regular Class B license. This includes full-size buses, shuttle vans, and passenger vans operated by a business. The distinction matters: a Class B CDL is different from a Class B regular license.

Vehicles used for commercial purposes—like a box truck operated as a delivery vehicle for a business—may also require a CDL depending on the GVWR and how it is used. A pickup truck you own and use personally stays Class B. The same pickup truck operated as a commercial delivery vehicle might require a CDL. If you are unsure whether your work vehicle needs a CDL, contact your state's DMV or ask your employer; the penalties for driving without the right license are steep.

How to check what your Class B license covers

Your license itself lists restrictions and endorsements. Look at the back or the restrictions section—it will show codes that correspond to what you can and cannot drive. For example, some states use code "E" to mean no towing, or code "F" to mean automatic transmission only. Your state's DMV handbook explains what each code means. If you do not have your handbook, read it from your state's DMV website or pick one up in person.

If your license does not show a towing restriction, that does not automatically mean you can tow anything. It means you can tow within your state's default limits for Class B. Read your state's specific rules, not just your license. The safest approach is to call your state's DMV directly with your vehicle's GVWR and the trailer weight you want to tow, and ask whether you need a higher license class.

Upgrading from Class B to Class A

If you need to drive a heavier vehicle or tow a heavier trailer, you can upgrade to a Class A license. Class A covers any single vehicle under 26,001 pounds GVWR plus a trailer, with fewer restrictions on the trailer weight. The process varies by state: some require a written test only, some require a road test, and some require both. Most states let you keep your Class B and add Class A as an upgrade, so you do not lose anything.

The cost is usually modest—typically $20 to $50 for the license itself—but you may need to pay for a road test if your state requires one. Some states waive the road test if you already hold a valid Class B. Check your state's DMV website for the exact requirements and fees in your area.

Frequently Asked Questions

Can I tow a boat trailer with a Class B license?

Most states allow Class B drivers to tow small boat trailers under a certain weight limit, often 5,000 to 10,000 pounds. Check your state's DMV handbook or website for the exact limit. If your boat and trailer together exceed that weight, you will need a Class A license.

Do I need a special license to drive a motorhome?

Most motorhomes under 26,001 pounds GVWR can be driven with a Class B license. Some states require an RV endorsement or restrict motorhomes by length instead of weight. Check your state's rules before you rent or buy an RV.

What happens if I tow something I am not licensed to tow?

You can be cited for driving with an improper license class, and your insurance may deny a claim if you are in an accident. You are also liable for any damage. It is not worth the risk—upgrade your license if you plan to tow regularly.

Can I drive a commercial van with a Class B license?

It depends on the van's GVWR and how it is used. A personal van under 26,001 pounds is Class B. A commercial box truck or delivery van may require a CDL depending on its GVWR and whether it is used for business. Ask your employer or your state's DMV if you are unsure.

Is Class B the same in every state?

The basic definition is the same—vehicles under 26,001 pounds GVWR—but towing rules, endorsements, and restrictions vary by state. Always check your state's DMV handbook for the specific rules that explore to you.
