How long is your dangerous goods driver's certificate valid?

• A. One year
• B. Ten years
• C. Two years
• D. Five years

Answer: (D)

Dangerous goods training is time-limited, so the certificate you hold for ADR is valid for five years. This five-year window exists to ensure drivers refresh their knowledge on essential rules—packaging, labeling, documentation, and safe handling of dangerous goods—so standards stay current. Before it expires, you should complete a refresher course to extend your authorization to transport dangerous goods. If the certificate lapses, you aren’t legally permitted to carry dangerous goods until you renew. It isn’t one year, two years, or ten years—the standard validity is five years.
