What must all trucks do when lights are flashing at an inspection station?

When lights are flashing at an inspection station, it indicates that all trucks must report to that station. This requirement is in place to ensure that vehicles are subject to safety inspections and compliance checks, which are crucial for maintaining road safety and regulatory standards.

Trucks are typically required to stop at these inspection stations as a part of systematic checks that help to ensure they are safe to operate and meet legal requirements such as weight limits and safety protocols. Reporting to the inspection station allows authorities to conduct necessary inspections that help reduce the risk of accidents caused by equipment failure or other issues related to truck operation.

The other options would not align with safety regulations. Continuing to drive without stopping could result in penalties and compromise safety standards, while simply slowing down might not sufficiently comply with inspection requirements. Turning off their lights would also be counterproductive, as the flashing lights are a signal for the truck to stop and report for inspection.
