What should be checked regularly to maintain a tow truck's performance?

Regularly checking tire pressure and fluid levels is essential for maintaining a tow truck's performance because these components directly impact the vehicle's safety, efficiency, and reliability. Proper tire pressure ensures optimal traction, fuel efficiency, and longevity of the tires, which are critically important for the handling of the truck, especially when towing heavy loads.

Fluid levels—including oil, coolant, brake fluid, and transmission fluid—are equally vital, as they ensure that the various systems in the truck operate smoothly and effectively. Low fluid levels can lead to engine overheating, transmission issues, or brake failure, all of which can disrupt the performance of the tow truck and pose safety risks on the road.

While other options like the color of the vehicle, the audio system, and exterior cleanliness may contribute to the aesthetics of the truck, they do not significantly impact its performance or safety in the same way that tire pressure and fluid levels do. Focusing on these critical maintenance checks supports the overall operational integrity of the vehicle and ensures that it remains in safe working condition.
