254 questions, 12 of them written for Idaho.
The Idaho bank runs to 254 questions. 12 are written for Idaho specifically from the Idaho Code, 60 make up the shared national core of right of way, rules of the road and safety that every state tests, and 182 are sign recognition cards with official MUTCD sign artwork (public domain, via Wikimedia Commons). 8 of the 254 are rated hard, 2 of those from Idaho's own set.
The 12 questions written for Idaho.
These 12 split into 8 on rules of the road, 3 on safety and impairment and 1 on right of way, and each one names the rule it tests, so you learn the Idaho Code section rather than just the answer. The rest of the bank is the shared national core and the sign artwork every state uses. Here is what Idaho asks from its own code, and where each question comes from.
