A vehicle sobriety interlock system including a sobriety testing apparatus for testing a driver of a vehicle for intoxication and an interlock system responsive to test results from the sobriety testing apparatus for controlling ignition of an engine of the vehicle. The interlock system, in response to a test result indicating that the driver is sober, allows the driver to start the engine of the vehicle. During a vehicle warm-up time period of a predetermined length following start of the engine and before a transmission of the vehicle has been engaged for putting the vehicle in motion, the interlock system delays a retest of the driver with the sobriety testing system for intoxication.
