About the Idaho permit test
The basics, in plain English, from the Idaho Driver's Handbook.
Licensed as young as 15
Idaho can license you at 15, but anyone under 17 must first finish an approved driver training program and the graduated driver's license program. (Idaho Driver's Handbook, p. 3)
Driver training from 14½
Driver training (open from 14½) takes 30 classroom hours, 6 hours watching other students drive and 6 hours behind the wheel with an approved instructor. You buy a Driver Training Instruction Permit before the first class. (Idaho Driver's Handbook, p. 19–20)
Six supervised months
After training comes at least six months of supervised driving with no violations: 50 hours or more, 10 of them at night, with a licensed driver 21 or older in the front passenger seat. (Idaho Driver's Handbook, p. 19)
Limits for new teen drivers
Under 16, you may drive only from 5 a.m. to 10 p.m. unless a licensed driver 21+ sits beside you. Under 17, for six months after licensing, you may carry only one passenger under 17 who isn't family. (Idaho Driver's Handbook, p. 16)
40 questions, six misses allowed
The Class D knowledge test has 40 questions taken from this handbook. Miss seven and you fail, then wait three days and pay the fee again. (Idaho Driver's Handbook, p. 32)
Alcohol limits by age
Idaho treats you as under the influence at .02 if you are under 21, .04 in a commercial vehicle and .08 for drivers 21 and older. (Idaho Driver's Handbook, p. 131)
Idaho permit test FAQ
How many questions are on the Idaho permit test?
The Class D knowledge test has 40 questions drawn from the Idaho Driver's Handbook. You can get up to six wrong, so 34 right answers pass. It is offered in English, Arabic, Chinese, Farsi, French, Korean, Russian, Serbo-Croatian, Spanish, Swahili, Vietnamese and American Sign Language. (Idaho Driver's Handbook, p. 32)
What if I fail the Idaho knowledge test?
Wait three days before testing again, and pay the knowledge test fee a second time. A failed skills test works the same way: three days, and both fees (county and examiner) are paid again. (Idaho Driver's Handbook, p. 32–33)
How old do I have to be for Idaho driver's training?
Fourteen and a half. A Driver Training Instruction Permit lets anyone from 14½ up to 17 attend a public school or private driver training program, driving only with the instructor while enrolled. (Idaho Driver's Handbook, p. 15)
What is Idaho's supervised instruction period?
After driver training, teens under 17 drive for at least six months with no violations, logging 50 hours or more (10 at night) with a licensed driver 21 or older beside them and nobody else in the front seat. A traffic conviction cancels the permit and the six months start again. (Idaho Driver's Handbook, p. 19)
