Which of the following items are checked at a truck inspection station?

At a truck inspection station, ensuring compliance with regulations regarding the dimensions of the load, specifically height, length, and width, is crucial. This is because the load must meet specific legal requirements to prevent accidents and damage to infrastructure. A load that exceeds permissible dimensions can pose risks not only to the vehicle itself but also to other road users and the environment.

Assessing the load's dimensions helps ensure safe passage on roadways, especially on bridges and overpasses, which have strict size limitations. Authorities verify compliance to maintain safety and avoid potential fines or penalties for breaches of transportation laws.

While factors like cleanliness, fluid levels, and the condition of cargo are important for vehicle maintenance and safety, they do not specifically pertain to the regulatory checks focused on at inspection stations in the context of load compliance. Therefore, the emphasis on load dimensions is paramount in such inspections.
