What device may a court require to test a driver's blood alcohol before the car starts?
The answer
Answer: C. The court may require installation of an ignition interlock device, which mechanically tests the driver's blood alcohol level before the vehicle can be started. If eligible, the court may also order specialized driving privileges. A conviction can also bring a suspension of its own, and the court sets conditions placed on your driving privileges.
