How often must the certificate carried by the driver be updated?

The certificate that a driver must carry to operate a motor vehicle transporting hazardous materials is required to be updated every three years. This timeframe is established to ensure that all drivers stay current with the latest safety regulations, procedures, and knowledge regarding the transportation of hazardous materials. As hazardous materials can change in terms of handling, regulations can also evolve to enhance safety, necessitating periodic re-evaluation and training for drivers. By updating the certificate every three years, drivers can demonstrate their ongoing commitment to safety and compliance with the regulations governing the transportation of hazardous materials.
