South Dakota CDL: How the Seasonal Farm-Related Restricted CDL Works

It is the first week of harvest, and a farm service company needs one more driver to run a loaded truck between the field and the elevator. The new hire has a regular license, a clean record and no CDL. Does the company have to wait weeks for a full license? Not always. South Dakota has a restricted seasonal CDL built for this kind of work, and it is the most important thing to understand if you want a South Dakota CDL for farm-related jobs.

What is the South Dakota restricted seasonal CDL?

The restricted seasonal CDL is a limited license for employees of the farm-related service industry. To qualify you need a valid license that you have held for one year, plus a good driving record over the past two years. The big difference from a standard CDL is that all of the tests are waived. The trade-off is a long list of limits, so read them closely before you plan a work season around it.

• It covers Class B and Class C vehicles only. Class A combinations such as a tractor-trailer are outside the license.
• It is time-limited: one 180-day period or two 90-day periods in a year.
• You must stay within 150 miles of the place of business or the farm being served.
• Hazardous materials are limited to a short list of exceptions (see below).

What hazmat can you haul on a seasonal CDL?

Farm work often means fertilizer and fuel, so the hazmat exceptions matter. South Dakota's seasonal CDL exceptions include liquid fertilizer in 3,000 gallons or less and diesel fuel in 1,000 gallons or less. Treat those numbers as ceilings. If a load goes beyond what the exceptions allow, the seasonal license is no longer the right license for that trip.

Before you accept a seasonal job, ask your employer in writing which trucks you will drive and what you will haul. A Class A tractor-trailer, a trip past the 150-mile limit or an oversized chemical load each puts you outside the seasonal license.

When do you need a full South Dakota CDL?

If the job reaches beyond the seasonal limits, you need a standard CDL. That means a commercial learner's permit (CLP), a period of supervised practice and then the skills test. Here is the path in plain order:

1. Pass the CDL knowledge tests that match the class and endorsements you want, and get your CLP.
2. Practice with a qualified supervisor. A CLP holder must ride with a driver who is at least 21, sits next to them and holds the same commercial classification.
3. Book the skills test while your permit is still valid. Skills tests count only while the CLP is valid, so do not let it run out.
4. Pass all three areas of the skills test: pre-trip inspection, basic vehicle control and on-road driving.

What is the minimum age for a South Dakota CDL?

Age decides where you can drive. An interstate South Dakota CDL holder must be at least 21. Drivers who are 18 to 20 can get an intrastate-only CDL or CLP, which keeps them inside the state. That matters in a state where I-90 carries freight straight across to neighboring states. A 19-year-old farm hand can haul within South Dakota but cannot take the same truck across the state line.

What happens if you drive a commercial vehicle without a CDL?

South Dakota treats this seriously, and the rule reaches employers too. Driving a commercial vehicle without a CDL, or holding more than one license, can bring jail time and/or fines of up to $5,000. An employer who lets such a driver operate a commercial vehicle faces the same penalties. For a small farm service business, that is a strong reason to match every driver to the right license class before the season starts.

Seasonal CDL mistakes to avoid

• Assuming the seasonal license works like a full Class A. It does not.
• Losing track of days. The seasonal period is limited, so count from the first day you rely on it.
• Ignoring the 150-mile limit when a customer asks for one longer run.
• Hauling more fertilizer or fuel than the exceptions cover.
• Waiting until the busy season to find out you need a full CDL.
