A Saskatchewan Class 2 licence is for buses seating more than 24 passengers while carrying passengers, and it also covers Classes 3, 4 and 5. Class 2 applicants write five papers: Sign (30 questions), Basic Class 5 (20), Class 2 (15), Class 3 (10) and Class 4 (10). Buses with air brakes need the A endorsement, and school buses need the S endorsement on top of the licence class.
This page draws on the topics we group under the Class 2 paper: loading zones and doors, bus turns and leaving the curb, passenger precautions, standing passengers, railway crossings, refusing passage, and the school bus rules for safety lights, stop arms and crossings. Every explanation cites the page of the SGI Professional Driver's Handbook it comes from. When you are scoring well, take the full mock exam.
