QUICK TAKEAWAY
Alberta's impaired driving legislation imposes penalties on first-time offenders with blood alcohol concentrations between 50-100 milligrams per 100 millilitres of blood, including license suspension, vehicle seizure, and fines. Appeals for Immediate Roadside Sanctions (IRS) can be made within seven days and may require a lawyer with experience in both criminal and administrative law. Penalties for first-time offences include fines, license suspension, interlock device usage, and driving record entries. Civil and criminal charges are possible, and penalties for second-time offenders are more severe, potentially including jail time and alcohol education programs.
