What is the vehicle impoundment duration for a high BAC (over .16 or refusal) on a 3rd or subsequent offence?

Answer: B — 60 days

According to most state laws, the vehicle impoundment duration for a high BAC (over .16 or refusal) on a 3rd or subsequent offense is 60 days. This means that the offending vehicle will be held by law enforcement for a total of 60 days. Option A is incorrect because it is a relatively shorter duration and might be applicable for a first or second offense. Option C is also incorrect as it is the least severe duration and might be applicable for a lesser offense. Option D is incorrect as it is the shortest duration and might be applicable for a minor offense. Overall, the correct answer B, is the most suitable duration for a high BAC or refusal on a 3rd or subsequent offense, as it is the longest duration and reflects the severity of the offense.
