South Dakota CDL Medical Card Requirement Coming July 2026

Starting July 1, 2026, South Dakota is aligning with federal FMCSA medical certification requirements, and if you're a CDL driver who has been operating without a medical card, you need to act now. This is not a minor update. Thousands of South Dakota CDL drivers who have never had to deal with this requirement before are now at risk of being placed out of service and having their CDL downgraded if they don't take action before the deadline.

Why This Is a Big Deal for South Dakota CDL Drivers

South Dakota has operated differently than most states. For years, many CDL drivers who operated intrastate only or carried a K restriction were not required to maintain a DOT medical card. That created a large group of drivers who have been legally operating without medical certification, and that is exactly what is changing.

This change is happening because South Dakota must align with federal FMCSA requirements to maintain consistency with national CDL standards and remain compliant with federal transportation funding requirements. Federal regulations require medical qualification for CDL drivers, typically those operating vehicles over 26,000 pounds, and states must meet these standards. This brings South Dakota in line with how the rest of the country already operates.

Who Is Affected by the South Dakota CDL Medical Card Requirement?

1. CDL Drivers Operating CDL-Required Vehicles
2. Intrastate Drivers
3. Drivers with a K Restriction
4. Drivers Without a Medical Certificate

Bottom line: If you hold a South Dakota CDL and have been operating without a medical card, you should assume this applies to you.

What South Dakota CDL Drivers Will Be Required to Do

To remain compliant with the new South Dakota CDL medical card requirement, you will need to:

• Obtain a valid DOT medical certificate
• Complete your DOT physical exam with a certified medical examiner
• Be classified as either:
  • Non-Excepted Intrastate (NA): if you operate only within South Dakota
  • Non-Excepted Interstate (NI): if you operate across state lines and meet federal medical qualification standards
• Ensure your results are submitted electronically to the FMCSA
• Verify your status is updated on your motor vehicle record (MVR)

It's also worth noting that many South Dakota drivers have historically remained intrastate because a medical card wasn't required. With this change, drivers who meet federal medical standards may now have the option to operate as interstate (NI), opening up more opportunities on the road.

Why So Many South Dakota CDL Drivers Are Confused Right Now

The state is expected to notify approximately 28,000 South Dakota CDL holders about this change. However, many drivers have not received those letters, and many don't realize they're affected because this requirement simply never applied to them before.

At the same time, the compliance system is now fully electronic, medical examiners are booking out fast, and DMV processing delays are increasing across the state.

Do not rely on a letter from South Dakota DPS. You need to act now, ahead of the July 1 deadline.

What Happens If South Dakota CDL Drivers Do Nothing?

There are two critical timelines to understand.

Before July 1, 2026 You may still be operating legally, but you risk limited DOT physical appointment availability, electronic processing delays, and missing the compliance window entirely.

After July 1, 2026

1. Roadside Impact
   CDL drivers without a valid DOT medical card can be placed out of service immediately during a roadside inspection. You cannot continue driving, your trip ends on the spot, your load may be delayed or reassigned, and your company operations may be disrupted. This is immediate, real-world impact — not something that can be resolved on the side of the road.
   
   
2. CDL Downgrade
   If your medical certification is not valid, your South Dakota CDL will be downgraded to a Class D license, typically within 60 days. That means loss of your ability to operate commercially, immediate income disruption, and a more complex reinstatement process.
   
   
3. At CDL Renewal
   If you attempt to renew your CDL without a valid DOT medical certification on file, you will not be issued a CDL. You'll receive a Class D license instead. There is no grace period at renewal.
   
   
4. Risk of Retesting
   Your CDL won't be immediately revoked, but if too much time passes or your license expires, you may be required to retake both written and skills tests to reinstate your CDL in South Dakota.
