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

The maximum weight limit on a tandem axle on designated state and local streets and highways is 34,000 pounds. This weight limit is established to ensure the safety and structural integrity of the roadways. Tandem axles, which consist of two axles spaced close together, are designed to distribute weight more evenly across the road surface, thereby minimizing damage and maintaining safe driving conditions.

Staying within the specified weight limit helps in reducing wear and tear on roads and bridges, which can lead to costly repairs and safety hazards if exceeded. This limit aligns with federal guidelines and also reflects the specific regulations adopted by many states, including Illinois. Properly adhering to these regulations is crucial for drivers to ensure the safety of themselves and others on the road.
