New-driver rules in Iowa
Iowa licenses teens through a three-step graduated system: instruction permit at 14, intermediate license at 16, and full license at 17. Reaching the intermediate stage requires holding the permit for 12 months, staying crash- and violation-free for the 6 consecutive months before applying, completing driver education, and logging 20 supervised practice hours with 2 of them after dark. Intermediate licensees may not drive unsupervised between 12:30 a.m. and 5 a.m. and, for their first 6 months, may carry only one unrelated minor passenger unless a parent or guardian waives that limit.
