At what speed can a bus safely take a turn without risking a loss of control?

• A. 1-2 mph
• B. 4-5 mph
• C. 3-5 mph
• D. 7-8 mph

Answer: (C)

A bus can safely take a turn without risking a loss of control at a speed of 3-5 mph because this speed range allows for sufficient maneuverability while maintaining stability. Buses, due to their size and weight, have a higher center of gravity compared to smaller vehicles, which means they are more susceptible to tipping over if they take turns too quickly. The 3-5 mph range provides a balance between speed and the necessary control to navigate safely through curves and turns. Maintaining this speed ensures that the centrifugal force acting on the bus does not exceed the grip of the tires on the road surface, thereby minimizing the risk of skidding or losing control. In scenarios where the turn is sharper or there are adverse weather conditions, it is even more critical to adhere to lower speeds, reinforcing the importance of this safe speed range for bus operators.
