Does a police officer need a search warrant to search my car?

Gary Churak's Answer

No, it’s not going to matter because the law is pretty established that once an officer pulls you over for any kind of infraction of a law, which could be speeding or running at red light or even crossing lanes without signaling, he has the ability to search your vehicle if he has any kind of reasonable cause to do so. So, it is not a defense that he didn’t have a warrant and he went and searched your vehicle and found the Marijuana. Often, I have that situation come across where the officer says he smelled Marijuana in the vehicle but that is the usual excuse officers use for searching vehicles.
