Ontario Bus Driver Knowledge Practice Test 2026 – All-in-One Study Guide for Exam Success!

The class of Ontario License needed to drive any ambulance or bus (excluding school buses) carrying between 10 and 24 passengers is class D. This is because a class D license allows for the operation of any vehicle designed or used to transport more than 10 people. This includes larger passenger vehicles like buses and ambulances. While options A, C, and D are also types of licenses in Ontario, they are not specifically for vehicles of this size and capacity. Option B, a class G license, only permits the operation of vehicles with a maximum of 11 passengers, making it incorrect for this scenario.
