What action is taken when a transport unit does not comply with safety standards?

When a transport unit does not comply with safety standards, the appropriate action taken is removal from service. This is crucial in ensuring public safety and maintaining the integrity of the transport industry. Removal from service indicates that the vehicle is not fit for operation until it meets the necessary safety standards. This action protects both the driver and the public by preventing potential accidents or hazards caused by unsafe vehicles.

The other responses may involve consequences as well but do not directly address the immediate safety concern. For instance, revocation of registration is a more administrative penalty that may follow if non-compliance continues, while the issuance of a fine serves as a financial penalty for non-compliance but does not directly remove the unsafe unit from the roads. Reinspection could be part of a process to ensure compliance but would not be an immediate reaction to an identified violation. Hence, removal from service is the most immediate and effective action to safeguard everyone involved.
