Overloading an axle will primarily affect which aspect of performance?

• A. Braking efficiency
• B. Steering stability
• C. Ride comfort
• D. Fuel economy

Answer: (A)

Overloading an axle increases the load the braking system has to manage and the tires have to grip. Because more kinetic energy must be dissipated during a stop, stopping distances can lengthen and brakes can overheat, reducing braking efficiency. This direct strain on the brakes and tyre grip makes braking efficiency the aspect most affected by extra load. While steering stability, ride comfort, and fuel economy can also be influenced by overload, they’re secondary to the braking demand placed on the vehicle.
