Which of the following actions can lead to immediate vehicle impoundment in Ontario?

Driving with a Blood Alcohol Concentration (BAC) over .08 is a serious offence in Ontario and can lead to immediate vehicle impoundment. This is because operating a vehicle under the influence significantly increases the risk of accidents, endangering both the driver and others on the road. The legal threshold of .08 BAC represents a dangerous level of impairment, and enforcement agencies prioritize road safety by imposing strict penalties for such infractions. As a result, individuals caught driving with a BAC above this limit not only face immediate consequences such as vehicle impoundment but also potential criminal charges, fines, and license suspensions.

The actions mentioned in the other options, while they may result in penalties or fines, do not carry the immediate impoundment consequence that driving over the legal BAC does. Therefore, understanding the severity of driving under the influence is crucial for drivers in Ontario.
