Before test day
Instruction permit at 14
Teens can get an instruction permit from age 14 after passing the knowledge and vision tests, with a parent or guardian's written consent. (Iowa DOT: Instruction Permit for Under Age 18)
The test can be taken at home
Under 18, the knowledge test can be taken at a DOT or county treasurer location, at a participating school, or at home with a parent who holds an Iowa license as the proctor. (Iowa DOT: Instruction Permit for Under Age 18)
Driver education before 18
Applicants under 18 must finish an Iowa-approved driver education course; doing so usually replaces the DOT driving test. (Iowa Driver's License Manual, p. 5)
A year on the permit
The intermediate license comes at 16 at the earliest, after 12 months with a permit, driver education and six months in a row with no violations. (Iowa DOT: Intermediate License)
No phones for teen drivers
Drivers under 18 on a permit, intermediate or school license may not talk on a phone unless parked off the road. Every driver must keep the phone hands-free. (Iowa Driver's License Manual, p. 36)
Late-night limit after the permit
With an intermediate license, teens may drive alone from 5 a.m. to 12:30 a.m.; outside those hours they need a supervising adult or a parent's waiver for school or work. (Iowa DOT: Intermediate License)
