What is the weight limit for a 5-axle combination vehicle on designated highways?

The weight limit for a 5-axle combination vehicle on designated highways is established at 80,000 pounds. This limit is set to maintain road safety and integrity by preventing excessive weight that could lead to road damage. The federal law allows a maximum gross vehicle weight of 80,000 pounds for vehicles that are properly configured with the appropriate number of axles, which is crucial for distributing the weight evenly. Adhering to this weight limit also helps with vehicle handling and braking performance, ensuring that the driver can maintain control of the vehicle under various circumstances. Additionally, it is important for compliance with state and federal regulations to avoid penalties and ensure roadway safety for all users.
