How many DUIs do you give out to people who blow a 0.0? If a driver refuses to blow standardly a blood test is allowed/offered. It is only admissable in court if performed by a medical professional. Which means if they just asked her to blow and it was a 0.0… and they still didn’t believe her, taking her to a hospital instead of jail would be the logical next step to have the blood test performed where a health professional may have had a shot at catching said health issues.
