Ontario MTO Truck Knowledge Practice Test

The correct action that can be taken against your license if you fail or refuse to provide a breath, blood, oral fluid, or urine sample when requested by the police is a suspension for 90 days. This penalty reflects the serious nature of refusing to comply with law enforcement requests related to impaired driving investigations. The law is designed to deter individuals from resisting testing, as it is crucial for maintaining road safety. Other actions, such as revocation for 1 year, may apply in different contexts or scenarios, but specifically, the immediate consequence for refusing to provide a sample is a 90-day suspension. Fines or points deductions are also possible in various situations, but they do not apply directly to the refusal to provide a sample in this instance.
