The requirement to check the tires of a placarded trailer with dual tires every time you stop is rooted in safety regulations and best practices for vehicle maintenance. This frequency ensures that drivers can identify any issues such as tire damage, under-inflation, or obstructions, which could lead to serious accidents or increased tire wear over time.

Frequent checks help ensure that the tires are in optimal condition, particularly for a trailer that carries hazardous materials, as outlined by the placards. Regular monitoring allows the driver to address any tire issues immediately, enhancing safety for both the driver and other road users.

By checking the tires at each stop, drivers can maintain compliance with safety standards and regulations, thereby ensuring a higher level of operational safety while on the road.
