About the licence

Ontario bus licences: Class B, C, E and F

To drive a school bus in Ontario you need a Class B (more than 24 passengers) or Class E (24 or fewer) licence. Other buses need a Class C (more than 24 passengers) or Class F (24 or fewer, including ambulances). School-bus applicants also complete an approved School Bus Driver Improvement Course, a criminal record check and a medical report.

The Class B and E knowledge test has two parts: traffic-signs recognition and operating knowledge of a school bus. The Class C test covers operating buses and trucks. MTO says to study the Official MTO Bus Handbook, but it doesn't publish the number of questions or the pass mark.

ExamHub's free practice quiz has 200 original questions built chapter by chapter from the handbook and the Highway Traffic Act. Signs are described in words.

How many questions are on the test, and what is the pass mark?
