People may think that failing a blood test will automatically result in a conviction. However, that may not always be the case. As is true with all drunk driving cases, certain procedures must be followed in order for evidence to be used in court.
The National Transportation Safety Board (NTSB) is meeting to review a recommendation that all states require convicted first-time drunken driving offenders to use an ignition interlock device in their car thereafter. The measure is already required in 17 states where the dashboard breath test prevents the car's ignition should the would-be driver have too high of an alcohol concentration on their breath.
