Maximum axle weights are set by a _________ formula

Maximum axle weights are set by a _________ formula

• A. Bridge
• B. Weight
• C. Traffic
• D. Load distribution

Answer: (A)

Maximum axle weights are set by a bridge formula because this rule uses how many axles a vehicle has and how far apart they are to determine how much weight each axle can legally carry. This standard exists to protect bridges from damage by ensuring the load is distributed in a way that the structure can safely support. If you only relied on a general weight cap, traffic flow, or a generic idea of load distribution, you wouldn’t be accounting for how the specific axle configuration affects stress on bridges. The bridge formula provides the per-axle limits tailored to the vehicle’s setup, which is why it’s the correct basis for setting maximum axle weights.
