What does it mean if a commercial vehicle is "overweight"?

When a commercial vehicle is described as "overweight," it signifies that the vehicle exceeds the maximum allowable weight limit set for its classification. Each type of vehicle has specific weight limitations established by regulations to ensure road safety, reduce wear on infrastructure, and improve fuel efficiency. When a vehicle exceeds these limits, it may face penalties, restrictions, or be deemed unsafe for operation. This condition could affect the vehicle's handling, braking, and overall performance, posing dangers to both the driver and others on the road.

Other options do not accurately define "overweight." A flat tire refers to a mechanical problem unrelated to weight. Being loaded with dangerous materials pertains to cargo type rather than weight. Finally, having more than five axles describes a vehicle's configuration, not its weight status.
