An increase in speed will cause what effect on traction?

• A. Increase
• B. Decrease
• C. No effect
• D. Varies based on road conditions

Answer: (B)

An increase in speed will decrease traction because as a vehicle moves faster, the contact between the tires and the road surface becomes more limited. Tires can lose their grip more easily at higher speeds due to the increased force of momentum, which can contribute to slipping, skidding, or hydroplaning on wet or uneven surfaces. The relationship between speed and traction is crucial for maintaining control of the vehicle, especially in a school bus, where safety is paramount. At higher speeds, drivers have less time to react and are more susceptible to losing control in adverse conditions, making it essential to understand the impact of speed on traction for effective driving practices and safety measures.
