Driver Education and Iowa GDL Requirements
This domain tests how well you can teach Iowa's graduated driver licensing (GDL) ladder and the driver-education requirements behind it. Expect questions on permit eligibility, supervised-driving logs, intermediate-license restrictions, and the holding periods that move a teen to a full license.
The three-step ladder
- Instruction permit: minimum age 14; an applicant under 18 must be enrolled in or have completed an approved driver-education course; parent or guardian consent; knowledge, vision, and signs tests.
- Permit driving: accompanied by a licensed driver 21 or older in the front seat; all occupants belted.
- Intermediate license: minimum age 16; permit held at least 12 months for under-18 applicants; driver education completed; 20 supervised hours logged, including 2 at night; no moving violations or at-fault crashes in the preceding six months.
- Intermediate restrictions: no driving 12:30 a.m. to 5 a.m. except for school, work, or religious activities; for the first six months, no more than one unrelated minor passenger.
- Full license: at 17 after 12 months of intermediate driving with a clean record; otherwise at 18.
Driver education's role
Approved courses include at least 30 classroom hours and 6 behind-the-wheel hours. Instructors document completion and verify supervised-driving logs, and the school retains records supporting the GDL application.
Worked example
A student turns 16 today, has held a permit 10 months, completed driver education, and has 24 supervised hours, 3 at night. Is she eligible for the intermediate license? No. The 12-month permit hold is not met even though the course and hours are complete. The correct answer is to wait two more months; turning 16 alone does not unlock the intermediate license.
Traps
- Treating age 16 as the only requirement; the 12-month hold is separate.
- Counting all 20 hours as daytime; at least 2 must be at night.
- Letting a 15-year-old drive with a 19-year-old supervisor; the accompanying driver must be 21 or older.
- Assuming intermediate restrictions end at 17; the curfew continues until full licensure.
