Maryland parole officers have not been reporting drunken drivers’ probation violations to courts, according to an audit released Monday. In one case, a Maryland resident — who has been convicted three times of driving while intoxicated or under the influence — violated probation 14 times in six months. The suspect’s repeated attempts to drive after drinking were stopped by a court-ordered ignition interlock system, which requires him to pass a breathalyzer test to start his car.

The breathalyzer measured and logged his blood alcohol content every time it surpassed the legal limit.
