In this episode from the seventh season of reality series Motorway Patrol, Constable Mike Taylor is called out to Auckland's northwestern motorway when a car veers off the road in wet conditions, crashes through a fence and lands upside down in a mangrove swamp. While the fire brigade get to work, the shaken driver faces up to driving without a valid licence. Licence issues are again in play when an officer detains a flagged vehicle outside a McDonald's in Swanson, and things get serious for a carload of teens pulled over for speeding after a "strong smell of cannabis" wafts over Constable Ian Carter.
