Do load limit signs on bridges apply to all vehicles on the road?

Load limit signs on bridges indicate the maximum weight that a bridge can safely support. The correct response highlights that those carrying an oversize load permit may be exempt from these limitations. This exemption is crucial for certain vehicles that have received special authorization to transport heavier loads due to their specific requirements and safety measures.

For vehicles operating under special permits, there is typically a detailed assessment of the bridge’s capacity and the vehicle's weight distribution. This allows for necessary adjustments to be made to ensure the safety of both the vehicle and the bridge structure while acknowledging that some regularly heavy vehicles may need to operate on certain routes.

Understanding this context emphasizes the importance of compliance with load limit signs, except for vehicles that have received explicit permission, ensuring safety while accommodating the needs of commercial transport.
