On a tandem axle, what is the limit for designated state and local highways?

In the context of tandem axles on designated state and local highways, the weight limit is established at 34,000 pounds. This limit is significant because it aligns with federal guidelines which are often adopted by states to ensure safety and structural integrity of roadways. The tandem axle configuration, which includes two axles spaced closely together, allows for a specific weight distribution that is crucial for maintaining vehicle control and preventing road damage under heavy loads.

Following established limits helps in reducing wear and tear on the pavement and enhances the safety of all road users by minimizing the risk of accidents related to overloading. These weight restrictions are carefully set by transportation authorities based on engineering studies and the ability of road structures to support certain weight levels without compromising serviceability and safety.
