A man who banked his hopes on a loophole in the law may now have to face trial on drunk driving charges after a blood-alcohol test, which showed he was driving at twice the legal limit when he rolled his truck, will be allowed into evidence.The suspect, Pedro Ramirez Martinez, was assigned a July 27 trial date by Circuit Court Judge Bart Stanley after the judge rejected a motion to suppress his blood-alcohol test. The defense had maintained the intoximeter tester had not observed Martinez long enough before giving the test. Protocol requires a 20-minute observation period before giving the test to make sure the suspect puts nothing in his mouth that could taint the outcome.
