Idaho Driving Restrictions for 15-Year-Olds: Permit Rules

In Idaho, driving rules for 15-year-olds allow them to drive only on a supervised instruction permit, and only after they start an approved driver training program. The permit itself becomes available at 14 years and 6 months, but the license that follows requires six months of supervised practice, at least 50 hours behind the wheel, ongoing school enrollment, and a clean record during that whole stretch.¹

Who Can Start at 15

Idaho issues driver training permits to applicants who are at least 14 years and 6 months old, so nearly every 15-year-old is age-eligible.¹ Age alone isn’t the whole test, though. Anyone under 18 must be enrolled in school and meeting attendance standards to hold a permit or license. Idaho accepts public or private school enrollment, homeschool programs, GED preparation, college, and vocational or job training programs.²

The school link isn’t just a checkbox at application. If a teen drops out or falls below attendance standards after getting the permit, the school can ask the Idaho Transportation Department to suspend their driving privileges.²

Driver Training Is Required

Every Idaho applicant under 17 has to complete a state-approved driver training program before earning a license. The standard course is 30 hours of classroom instruction, 6 hours of in-car observation, and 6 hours of behind-the-wheel time with an instructor.³

Idaho also allows a parent-student on-road training path. A qualifying parent or guardian provides 92 total hours of on-road instruction over at least six months, including no fewer than 50 hours of street or highway driving and 10 hours of driving after sunset or before sunrise. The supervising parent must hold a valid Idaho license and can’t have had a suspension, revocation, or cancellation in the previous two years. The permit fee under this option is $10, compared with $15 for the standard course.⁴

Applying for the Permit

A 15-year-old needs proof of identity, legal presence in the United States, and Idaho residency. A certified birth certificate is the usual identity document, and it needs to list the parents’ names so the county office can verify the relationship of the adult signing for financial responsibility.³

A parent or legal guardian must sign for financial responsibility, taking on liability for the minor’s driving. The nonrefundable permit fee is $15 for the standard route.⁴ A 15-year-old going through GDL does not sit for a separate written knowledge test at the DMV before getting the supervised instruction permit; the knowledge component is built into the driver training course.⁵

Rules While Driving on the Permit

The rules during the supervised instruction period are strict, and they cover more than just having a licensed adult in the car.

Who Must Ride Along

Every time a 15-year-old drives on the permit, a supervising driver must sit in the seat beside them. That person must be at least 21 and hold a valid driver’s license.⁴ No one else is allowed in the front seat. Other passengers may ride in the back, and everyone in the vehicle must be belted or in a child restraint.¹

Daylight Only Under 16

Permit holders under 16 are limited to driving during daylight hours.¹ The 10 nighttime hours built into the 50-hour requirement have to happen under full supervision within that daylight rule’s exception for training.

No Texting Behind the Wheel

Idaho bans texting for all drivers. Fines start at $75 for a first offense, rise to $150 for a second within three years, and reach $300 for each additional offense. Three or more convictions within three years can bring a license suspension of up to 90 days.⁶ For a 15-year-old, a texting conviction also counts as a moving violation, which triggers the reset described below.

The Six-Month, 50-Hour Requirement

Once the supervised instruction permit is in hand, the countdown to a license begins. Idaho requires a minimum of six months of supervised driving and at least 50 hours behind the wheel, 10 of them at night. Before the license issues, a parent or guardian signs a GDL Requirements Verification statement certifying those hours.¹

The six-month clock resets if the permit holder gets a moving violation, has their privileges suspended, or breaks any permit restriction during that period. The countdown starts over from the date the permit is reissued, and it runs until it goes six clean months or until the teen turns 17, whichever comes first.⁴ A speeding ticket in month five means starting over.

Idaho publishes a “Checklist for Parent-Student On-Road Driver’s Training” so families can track hours, but the state does not require submitting a driving log to the DMV.³

What a Violation Costs

Idaho uses a graduated penalty structure for drivers under 17:

First moving violation: a written warning letter from the Idaho Transportation Department.
Second moving violation: a 30-day suspension, with no restricted permit available.
Third or additional violation: a 60-day suspension, again with no restricted driving.

⁷ Any moving violation during the supervised instruction period also resets the six-month clock.⁴ One ticket carries two consequences: the penalty itself and a delayed timeline for getting licensed.

Zero Tolerance for Alcohol

Any driver under 21 with a blood alcohol concentration at or above 0.02% faces criminal penalties in Idaho. A first offense brings a fine of up to $1,000, a one-year license suspension with the first 90 days absolute (no restricted permit at all), a mandatory alcohol evaluation, and possible treatment requirements. A second offense adds mandatory jail time and up to a two-year suspension.⁸ An alcohol-related conviction also triggers an SR-22 filing requirement, meaning the family’s insurer must file a certificate of financial responsibility. Reckless driving, fleeing a police officer, and leaving the scene of an injury accident also trigger SR-22 filings.⁹

Moving Up to an Intermediate License

After finishing driver training, logging 50 supervised hours over at least six clean months, and staying enrolled in school, a teen can take the road skills test. The test includes a pre-drive safety check with hand signals for turning and stopping.⁵

Passing earns an intermediate license, which loosens the rules without removing them. The nighttime restriction shifts from daylight-only to a curfew running 10 p.m. to 5 a.m. Drivers under 16 with an intermediate license may carry no more than one passenger under 17. Those passenger limits lift after six months or when the driver turns 17, whichever comes first. Full unrestricted privileges are the final stage of Idaho’s GDL program.

Insurance

Every driver in Idaho, including a supervised instruction permit holder, must be covered by auto insurance. The state’s minimum liability limits are $25,000 for bodily injury or death of one person, $50,000 for bodily injury or death of two or more in one accident, and $15,000 for property damage.¹⁰ Most 15-year-olds are added to a parent’s policy rather than carrying a separate one. Many insurers offer discounts for completing driver education or maintaining good grades. Driving uninsured is itself a violation that can trigger an SR-22 filing.⁹

Farm Tractors Are a Narrow Exception

Idaho exempts anyone from needing a driver’s license to operate a farm tractor or implement of husbandry when it is incidentally driven on a highway.¹¹ A 15-year-old moving a tractor between fields on a public road can do so without a permit. The exemption does not extend to a regular passenger vehicle, even for farm-related errands.
