What is the impoundment period for stunting on the 2nd or subsequent offences?

Answer: B — 3 days

The correct answer is B. The impoundment period refers to the time frame when a vehicle is held by the authorities due to an offence. For stunting on the 2nd or subsequent offences, the impoundment period is 3 days. This means that if a person is caught stunting for the second or more time, their vehicle will be impounded for a period of 3 days. The other options for 15, 7, and 30 days are incorrect as they do not match the specific impoundment period for stunting on 2nd or subsequent offences. Therefore, B is the best and most accurate answer for this question.
