In Idaho, a driver under 21 is considered to be driving under the influence at what blood-alcohol concentration?
- A 0.04 or more
- B 0.05 or more
- C 0.08 or more
- D 0.02 or more
Show answer
D. 0.02 or more
Idaho sets a much lower limit for young drivers: 0.02 for anyone under 21, compared with 0.08 for drivers 21 and older. For an under-21 driver, even a single drink can be enough to reach it.

A bicyclist approaches a stop sign in Idaho with no other traffic near the intersection. What does Idaho law require of the bicyclist?
- A The bicyclist must stop completely like a car
- B The bicyclist may proceed with caution without coming to a complete stop
- C The bicyclist must get off and walk the bike across
- D The bicyclist must wait for a car to arrive and wave them on
Show answer
B. The bicyclist may proceed with caution without coming to a complete stop
In Idaho, bicyclists do not need to come to a complete stop at stop signs. They must still yield to vehicles in or near the intersection and then proceed with caution, so drivers should expect this.
