Drivers who have been convicted of impaired driving in Alberta must take part in the Interlock Ignition Program. Drivers will be instructed to install the device for a set period, and they may not take it out until they have proven that they will not drive while impaired. In some cases, it may be possible to obtain an exemption that allows a driver to bypass participation in the program.
When asking for the exemption, those who have been convicted of a first offense with a blood alcohol content that was below 160 milligrams of alcohol in 100 millilitres of blood must explain why the exemption should be granted. In addition, the individual must include a valid blood alcohol reading. Furthermore, the driver must provide alternative actions that may be taken to ensure public safety during the disqualification period.
