In most cases, police officers are required to have a search warrant in order to search your vehicle; however, during a traffic stop, an officer is only required to possess probable cause to legally search your car.

An officer cannot search your car simply because they have a hunch you are up to something.
There are some exceptions to the search warrant requirement that enable police officers to search your vehicle. If you are arrested for a criminal offense while driving, the car can be searched incident to arrest. If the vehicle is impounded, it can be searched so there is an inventory of the vehicle. If an item of contraband is in plain view, the officer is allowed to go into your vehicle and seize it. At the border, if you are coming into the United States by driving a vehicle, that car is always subject to search.
First and foremost, it is imperative to remember that, if you are stopped by a police officer, remain cool and calm. If the officer chooses to detain you and requests to search your vehicle, you have the legal right to refuse consent to the search. You should clearly and verbally refuse; however, you should never, never physically resist an officer.
