What is the maximum weight limit on a 5-axle combination on designated state and local streets and highways?

The maximum weight limit on a 5-axle combination on designated state and local streets and highways is set at 80,000 pounds. This limit is established by federal regulations and is applicable for vehicles utilizing the National System of Interstate and Defense Highways, which directly influences state regulations as well. The 80,000-pound weight limit helps ensure the safety and structural integrity of the roadways while accommodating the transportation needs of larger vehicles that are commonly used for freight and cargo transport. This standard also supports a regulated approach to weight distribution across axles, which is crucial for maintaining road durability and preventing damage.
