Iowa Restricted CDL for Farm Service: Who Qualifies and How It Works

Iowa gives farm and farm-service drivers several ways to move a heavy truck, and people mix them up constantly. Before we get to the Iowa restricted CDL, here is how the four options compare.

• Farm exemption: for exempt farmers and their hired help driving a farm-owned truck. No commercial license is needed, but the exemption is narrow.
• Restricted CDL: for drivers serving farms, with limits on days and distance. This is the one most farm-service workers need.
• Standard CDL: no seasonal or distance limits. Required when the other options do not fit.
• Class D chauffeur's license: not valid as a CDL, no matter what you have heard at the elevator.

What is an Iowa restricted CDL for farm service?

The restricted CDL is a limited license for people who haul for the farm sector without holding a full CDL. Under federal rules the farm-related service industries include custom harvesters, farm retail outlets and suppliers, agri-chemical businesses and livestock feeders. Iowa builds its limits on top of that, and they are tight:

• It can be valid for up to 180 days in each calendar year.
• You may drive between your place of business and the farm being serviced, but not more than 150 miles from the place of business.
• You need two years of driving experience and a good driving record for the most recent two years.
• Each restricted CDL validation includes a search of your driving record.

If a job takes you past 150 miles, or you will need the truck for longer than 180 days in a year, a restricted CDL is the wrong tool and you should plan on a standard CDL.

Write down your likely work for the season before you apply: the farms you serve, the farthest haul, and how many days you expect to drive. If those numbers do not fit 150 miles and 180 days, ask the Iowa DOT about a standard CDL.

Does the farm exemption replace the restricted CDL?

Sometimes, but only for the right driver. The Iowa CDL Quick Guide says exempt farmers and hired help may operate a farm-owned truck anywhere in Iowa when hauling the farmer's own products, other than a truck-tractor with semitrailer. A separate limit applies to hired help age 18 or older driving a farm-owned special truck: the guide measures it from the farmland, and lists 100 miles. A restricted CDL is for a different situation, where you work for a business that serves farms and is not the farmer.

The Quick Guide has been revised over the years, so read the newest edition on the Iowa Department of Transportation site before you decide which category you fall into.

What do you need before an Iowa CDL skills test?

If you need a full CDL, you start with a commercial learner's permit (CLP). Iowa requires one for a first-time CDL, after being without a CDL for one year, or for an upgrade that needs a skills test. The permit is valid one year with no renewal, and you wait at least 14 days before the skills test.

A permit is not a free pass to practice anywhere you like. Iowa CLP holders:

• cannot use a cell phone while driving a commercial vehicle;
• cannot carry passengers other than the accompanying CDL driver, other trainees and test examiners;
• cannot drive a commercial vehicle containing hazmat, or a tank vehicle containing cargo.

Knowledge tests are counted by questions and allowed misses. The Quick Guide lists air brake at 25 questions with 5 misses allowed, and combination, passenger, school bus, doubles/triples and tank at 20 questions with 4 misses each. The general knowledge test is longer, at 50 questions with up to 10 misses.

Which violations cost a farm driver the CDL?

Seasonal workers sometimes assume the rules relax when the work is temporary. They do not. Under Iowa Code 321.208:

• A 0.04 or higher BAC in a commercial vehicle, leaving the scene or refusing chemical testing brings a one-year disqualification.
• Two qualifying offenses lead to a lifetime disqualification, which can be reduced to ten years under federal rules.
• Railroad crossing violations bring 60 days for a first, 120 days for a second within three years, and one year for a third or later within three years.

An open container violation also brings a 24-hour out-of-service penalty for commercial vehicles, on top of the criminal penalty.

Rules, forms and eligibility details change, so confirm the latest requirements with the Iowa Department of Transportation, Motor Vehicle Division, before you apply.
