What can improve braking performance on wet roads for heavy vehicles?

Answer: D — Both B and C

Improving braking performance on wet roads for heavy vehicles is crucial for safety and stability. Proper tire pressure is essential because tires that are inflated to the recommended levels maintain optimal contact with the road surface. This contact enhances traction, allowing the vehicle to brake more effectively, especially in wet conditions where hydroplaning can occur. Advanced braking systems, such as anti-lock braking systems (ABS) or electronic stability control (ESC), further enhance braking performance. These systems help prevent wheel lock-up during hard braking, allowing the driver to maintain steering control and facilitating better stopping distances on slippery surfaces. Both maintaining proper tire pressure and utilizing advanced braking systems work in conjunction to maximize safety when braking on wet roads.
