Right to Demand a Blood Test for DUI

MVA 1988 s.185(3); MTP Rules 1989

You had one drink at dinner two hours ago. The officer holds up a roadside breathalyzer and says the reading is above the limit.

💬Plain English

If accused of drunk driving, you can insist on a formal blood test at a government hospital rather than accepting a roadside breathalyzer reading alone. The blood sample is the legally admissible evidence in court.

⚡ Key moment

A breathalyzer reading is an indicator — not conclusive evidence. The blood test at a government hospital is the standard admissible in court.

🗣️Say this at the stop

"I request a formal blood test at a government hospital as provided under MVA s.185(3). I do not accept the breathalyzer reading as conclusive."
