Do I need a search warrant for a vehicle after my K9 alerts to it?

No. Once a properly trained K9 alerts on a vehicle, that alert provides probable cause to believe contraband exists in the vehicle. Because of the vehicle exception to the warrant requirement, LE does not need a warrant to search the vehicle. Because a vehicle is inherently mobile, this creates a type of exigency that has been recognized by the courts in allowing probable cause searches of vehicles without a search warrant. Carroll v.
