- A. 25 mph, or as posted
- B. 15 mph
- C. 20 mph
- D. 35 mph on arterial roads through school zones
Show answer
A. 25 mph, or as posted — Idaho school zones are typically posted at 25 mph when children are present or crossing, though local authorities may set lower limits. Idaho requires drivers to stop for school buses with flashing red lights from both directions on undivided roads; on divided highways, only same-direction traffic must stop. School-zone violations carry enhanced fines.

Report a problemWhat is the maximum speed limit on Idaho's rural interstate highways?
- A. 75 mph
- B. 80 mph
- C. 70 mph
- D. 65 mph
Show answer
B. 80 mph — Idaho allows a maximum speed of 80 mph on rural interstate highways — one of the highest in the nation. The Idaho Transportation Department sets these limits based on engineering studies of roadway design speed, traffic volumes, and crash data. Urban interstates typically post 65–75 mph. Two-lane rural state highways are often 65 mph. The basic speed rule applies: drivers must travel at a safe speed for conditions, including reduced visibility, ice, or curves, regardless of posting.
