Manitoba Class 3 Drivers Licence Practice Test

What factors decide the amount of control a driver has over a vehicle on a curve?

1. The vehicle's color, shape, and size

2. The vehicle's speed, size, and weight

3. The driver's experience, age, and reaction time

4. The time of day and the weather conditions

The correct answer is: The vehicle's speed, size, and weight

At the top speed, the centrifugal force generated while taking a turn on a curve pushes the vehicle outwards, causing it to lose stability. The greater the speed, the greater force is generated, and the larger the vehicle, the more weight it carries, increasing the centrifugal force experienced. Therefore, the vehicle's speed, size, and weight are crucial factors that determine the amount of control a driver has over a vehicle on a curve. Options A, C, and D do not directly affect the vehicle's stability on a curve and are not related to the centrifugal force generated. The vehicle's color, shape, and size do not have an impact on its stability on a curve, while the driver's experience, age, and reaction time are also not significant factors in the control of a vehicle on a curve. The time of day and weather conditions may indirectly affect the control a driver
