Saskatchewan Driver Education GDL Class 7 Learner Practice Test

The mandatory suspension period prior to Ignition Interlock Device for a Criminal Code conviction for impaired driving or refusal for the 1st offence within 10 years is 3 months. Option A, 90 days, is equivalent to 3 months, but it is not necessarily the 'mandatory' suspension period. Option B, 60 days, is too short and does not meet the mandatory requirement. Option D, 1 year, is too long and does not meet the within 10 years requirement. Therefore, option C, 3 months, is the correct answer.
