CDL rules for NEMT drivers: the 16-passenger line and DOT medical cards

Three federal thresholds, three separate rulebooks

Federal rules draw three different lines for passenger vehicles. Each answers a different question, and mixing them up is how an owner ends up with an unlicensed driver or a missing medical card.

No Medicaid rule creates a special license class. Federal law asks only that each NEMT driver hold a valid license. CMS guidance says drivers need the correct, current license for each vehicle they drive, and it gives a chauffeur’s license, or an equivalent, for taxi and van drivers as one thing a state may demand (SMD 23-006). Broker contracts say the same. MTM’s standard provider agreement calls for a current license suited to the services and to the type of vehicle being driven. Our overview of NEMT driver requirements covers the rest of a driver’s file.

The CDL threshold: 16 people or 26,001 pounds

Part 383’s CDL rules reach intrastate and interstate driving alike, and they bind the employer as well as the driver. For CDL purposes, a vehicle is commercial when it fits one of three groups:

• Group A: a combination rated or weighing 26,001 pounds or more that tows more than 10,000 pounds. Rarely seen in NEMT.
• Group B: a single vehicle at 26,001 pounds or more, such as a large bus built on a truck chassis.
• Group C: anything lighter that was designed for at least 16 people counting the driver, such as a cutaway shuttle bus, or that hauls placarded hazardous materials.

Carrying passengers in any of these also takes the passenger endorsement, marked P on the license, which requires both a knowledge test and a skills test. For weight, the higher of the rated and the actual weight counts, so a heavily loaded vehicle rated just under the line can still cross it.

Seat count means the original design. FMCSA answered this in guidance dated March 1, 2019: taking seats out leaves a vehicle’s design capacity unchanged as long as it still carries passengers. Pulling seats out of a 16-passenger shuttle to make room for wheelchairs therefore does not take it below the line.

The same vehicle can sit on different sides of the CDL line and the medical card line:

To check your own vehicle, read the weight rating on its certification label and get the designed seating capacity from the manufacturer or converter in writing. The count includes the driver. Our GVWR entry explains the weight labels.

The 9-to-15 threshold and the DOT medical card

The second threshold belongs to the FMCSA safety rules, not the CDL rules. On interstate trips, a vehicle is commercial when it is rated or weighs 10,001 pounds or more, or when it carries, or was designed to carry, more than 8 people including the driver, and the trips are paid. A paid 12- or 15-passenger van crossing a state line qualifies, even though its driver needs no CDL.

Interstate commerce covers more than trips that end in another state. A ride between two towns in your own state counts when the route passes through a neighboring state.

When the safety rules apply, the driver must meet the Part 391 qualification rules, including:

That certificate is what most people call the DOT medical card. A separate exception covers 9-to-15-seat vans that run without direct compensation. Paid NEMT trips are compensated, so that exception does not help.

The sick-and-injured exception

The FMCSA safety rules list “the transportation of human corpses or sick and injured persons” among their exceptions. In an April 19, 2024 letter in a public docket, FMCSA’s Western Service Center explained how it reads that exception for a carrier running ambulance-style vehicles:

• The exception follows the trip, not the vehicle, and FMCSA applies it one trip at a time.
• It covers a person being carried to seek medical evaluation or treatment.
• It does not cover transport for other reasons. The letter’s example is a ride to a grocery store after a medical appointment.
• It never applies to the rules on operating authority and insurance.

For NEMT, a van running only medical trips across a state line may fall outside the Part 391 driver rules, while the same van on a non-medical errand does not. A CDL driver can certify to the state as excepted interstate only when every interstate trip falls under an exception. The letter answered one carrier’s facts, so get your own written answer from FMCSA before you drop medical cards on that basis. Operating authority and insurance apply either way. Our guides to DOT numbers for NEMT and out-of-state trips cover those rules.

Intrastate trips

States set the rules for trips that never leave the state, and some copy the federal thresholds. Michigan’s chauffeur guide requires a medical examiner’s certificate for anyone driving a vehicle of 10,001 pounds or more, one designed for 16 or more people, or one hauling hazardous materials. New York requires pre-employment and biennial medical exams for drivers of carriers covered by Article 19-A.

Chauffeur and for-hire licenses by state

Your state issues the license, so it can ask for more than the federal rules do. Some states add a license class or endorsement for paid passenger driving, and two effectively lower the CDL line for NEMT. Six examples:

For other states, the license class chapter of the state driver manual lists the classes for paid driving. When the manual is unclear, get the licensing agency’s answer in writing. The state guides for New York, California, and Michigan cover the rest of each state’s provider rules.

What changes once a vehicle needs a CDL driver

One vehicle over the CDL line brings federal employer duties, even if every trip stays in your state:

1. Confirm the license class and the P endorsement before the driver’s first shift in that vehicle, and again at each renewal.
2. Begin Part 382 drug and alcohol testing. None of the general safety-rule exceptions, the sick-and-injured one included, applies to testing. An owner who is the only driver still needs a random selection pool that includes at least one other covered driver.
3. Query the Clearinghouse. A full query, with the driver’s specific consent, comes before any safety-sensitive work, followed by at least one query per year.
4. Allow for licensing time. Once the learner’s permit is issued, the driver waits at least 14 days for the skills test. Drivers whose permit dates from February 7, 2022 or later also complete entry-level training from a registered provider before earning a first P endorsement.
5. Track medical certificates for drivers certified as non-excepted interstate, plus whatever your state requires of intrastate drivers.
6. Keep a second CDL holder on the roster, or one sick call parks the bus.

Our drug and alcohol policy template gives you a starting point for the written testing rules.

Settle the license question before a vehicle purchase

Answer the license question before you sign, because it decides who can drive the vehicle:

• Weight and seating. Get the weight rating and the original designed seating in writing from the seller or converter.
• Your state’s line. Check whether your state moves the threshold. California counts more than 10 people on paid trips, and New York treats ambulette vehicles as buses.
• Broker expectations. Ask each broker which license it wants on file for that vehicle.
• Interstate use. If the vehicle will carry paid riders across a state line, plan for the more-than-8-person threshold, medical cards, and operating authority.
• Driver cost. Price the CDL path for each driver who will use the vehicle, from the permit and training to the tests and the medical exam.

Tracking licenses and medical cards in HealthRide

Add each driver’s license and medical card to HealthRide as credentials, each with its own expiration date, and you get a reminder well before either one runs out. An expired required credential is flagged when a dispatcher assigns that driver, so a lapsed medical card shows up before the van leaves the lot. Driver and vehicle records sit together in fleet management.
