What must be verified during the pre-trip inspection of a truck-tractor or three axle vehicle?

• A. The engine oil level is sufficient
• B. The axle assembly has no breaks, cracks, holes, broken seals, or bends
• C. All tires are inflated to the correct pressure
• D. The headlights are functioning correctly

Answer: (B)

During a pre-trip inspection of a truck-tractor or three-axle vehicle, verifying the condition of the axle assembly is crucial for safety and performance. The axle assembly is vital because it supports the weight of the vehicle and ensures proper alignment and control while driving. Inspecting for breaks, cracks, holes, broken seals, or bends ensures that the axles are structurally sound and can handle the operational stresses encountered during travel. Any defects in the axle assembly could lead to severe handling issues, potential loss of control, or even catastrophic failure, putting the driver and others on the road at risk. Therefore, ensuring the integrity of the axle assembly is a key focus in pre-trip safety protocols.
