Understand Iowa’s teen licensing steps
Iowa’s graduated system includes an instruction permit, an intermediate license, and a full license. Minimum age, driver education, supervised practice, clean-record, consent, and testing requirements apply at different steps.
Know intermediate-license limits
Unsupervised driving is generally allowed from 5 a.m. to 12:30 a.m. A restriction may limit unrelated minor passengers during the first six months. Electronic communication and entertainment device use while driving is also prohibited for intermediate drivers, subject to Iowa DOT’s stated exception.
Prepare for Iowa road conditions
Review safe following distance, work zones, railroad crossings, sharing the road, and the Move Over or Slow Down law. Adjust speed and space for rain, snow, ice, low visibility, and changing traffic.
