What is the maximum truck axle weight based on 5 axles?

Based solely on the number of axles, a 5-axle truck can have a maximum gross vehicle weight (GVW) of 80,000 pounds. However, the actual maximum weight allowed for a truck depends on several factors, including state and federal regulations, bridge laws, and the specific truck configuration.

Here is a breakdown of the maximum axle weights for a 5-axle truck based on the Federal Bridge Formula:

- Single Axle: 20,000 pounds

- Tandem Axle (2 axles spaced close together): 34,000 pounds

- Tridem Axle (3 axles spaced close together): 42,500 pounds

To determine the maximum weight for a 5-axle truck, you would need to consider the axle configuration and the corresponding weight limits for each axle. For example, if the truck has 2 single axles and 3 tandem axles, the maximum weight would be:

2 x 20,000 (single axles) + 3 x 34,000 (tandem axles) = 112,000 pounds

It's important to note that these are general guidelines and the actual weight limits may vary based on specific regulations in different jurisdictions. It's always best to consult with the local authorities or refer to the relevant regulations to determine the exact maximum truck axle weight for a particular truck configuration and location.
