Manitoba Class 3 Drivers Licence Practice Test

The degree of sharpness a vehicle can turn depends on:

1. Engine size and weight

2. Turning radius and the amount of off-track of the rear tires

3. Wheelbase and height

4. Tire tread and brake condition

The correct answer is: Turning radius and the amount of off-track of the rear tires

Vehicles can turn sharper or more tightly when their rear wheels move in the opposite direction than their front wheels. This is called off-tracking. Other factors such as engine size and weight, wheelbase and height, and tire tread and brake condition, while relevant to the overall performance of a vehicle, do not directly affect its turning radius or ability to turn sharply. So, option B is the only valid answer as it correctly identifies the factors that affect the degree of sharpness a vehicle can turn.
