In order to apply for a CDL in Iowa, drivers must meet a few requirements. The first is that they must be 18 years old or older. When these applicants go to their local office of the Department of Transportation, they are going to need to present proof of their age and their identity as well as their Social Security numbers.

At the time of the application, they will need to pass an eye examination and a written examination that demonstrates general knowledge of the rules of the road. If they are going to add endorsements to their licenses, they will also need to take an exam for each one.

How Other Driver Licenses Are Affected

Once Iowa drivers earn their CDLs, they will not be able to hold it and another license from the state of Iowa or from any of the other 49 states. They will be required to surrender any other driver licenses they possess at the time that they are granted their CDLs.

How to Study for the Exams

Iowa residents can choose to enroll in a course at a community college where they will receive classroom instruction for the written test and driving instruction for the road test.  The written test covers topics found in the Iowa CDL Manual.

The Required Fees

Applicants will take the written examination first. After they pass, they will receive a learner’s permit. With payment of the $12 fee, the learner’s permit will remain valid for six months. During this time, the applicants will prepare themselves for their road skills tests. After they pass the road test, they will be granted their CDLs upon payment of the $40 fee. The CDL will remain valid for five years.

Endorsements will require extra fees. These endorsements will either be $5 or $10. For example, the tank endorsement is only $5, but the passenger endorsement is $10.

The Road Skills Test

After applicants have taken the time they need to practice driving the commercial vehicle, they can make an appointment with the Department of Transportation to take the road test. To avoid having to take these tests when they renew in five years, applicants must renew within 60 days of the expiration date.
