💡 Test Day Tips
- •The Idaho Class D knowledge test has 40 questions; you must answer 34 correctly (85%) to pass.
- •The legal BAC limit is 0.08 (0.04 for commercial drivers); drivers under 21 face a 0.02 limit. Refusing an evidentiary test brings a one-year suspension and a civil penalty.
- •Idaho uses a point system: accumulating enough points within set periods leads to suspension — for example, 12–17 points in 12 months results in a 30-day suspension.
- •Idaho law allows the 'Idaho Stop': a bicyclist may treat a stop sign as a yield and a red light as a stop-then-proceed when it is safe.
- •Studded tires are allowed in Idaho only from October 1 through April 30; you must move over or slow down for stopped emergency and maintenance vehicles.
