Generally, no. However, the police are allowed to search your car without a search warrant if there is probable cause to believe that there is evidence of a crime or contraband located in your car. The scope of a warrantless search of an automobile is defined by the object of the search and the places in which there is probable cause to believe that it may be found. For example: An officer pulls you over for speeding. You roll down your window and the odor or marijuana is apparent to the officer. The officer may now search your vehicle without a warrant based on the plain smell of the marijuana. The officer may search any place where the marijuana may be found which includes the center console, glove box, the trunk of the vehicle, and even any bag in the vehicle that is large enough to hold marijuana.
