How long must a carrier keep a copy of each driver's TDG certificate?

The requirement for a carrier to keep a copy of each driver's TDG (Transportation of Dangerous Goods) certificate for a minimum of 2 years is established to ensure compliance with safety regulations in the transport of hazardous materials. This duration allows regulatory agencies to verify that all personnel involved in the transportation of dangerous goods have been properly trained and certified in handling those materials, thereby enhancing overall safety.

The retention period of 2 years provides a sufficient timeframe for audits and inspections by authorities, helping to ensure that the organization is following the necessary protocols to protect both the public and the environment. Keeping these records for this duration also supports accountability, as it allows for traceability regarding who was trained and when. This is particularly important in industries where the risks associated with mishandling dangerous goods can have severe consequences. Other timeframes mentioned, such as 1, 3, or 4 years, do not align with the established standard for compliance regarding TDG certification retention.
