Abstract

Ignition interlocks based on fuel cells have been in field service in Alberta Canada starting in May of 1994. Data on models which have many of the features of this latest generation of interlocks are given based on experience in both Alberta and the state of Michigan, USA which indicate that these devices should be highly effective in deterring drunk driving. It is shown that the key to effectiveness in an interlock is a combination of strict monitoring of the person on the program, coupled with highly effective methods of preventing the offender from cheating the device. Data to date indicated that these latest devices should reduce recidivism compared to license suspension by better than 90 percent. The methods that are used to accomplish this high degree of anti-circumvention are discussed. In addition, the problem of making field operation reliable and accurate over the range of temperatures encountered in Alberta Canada have been overcome and will be described.
