A: Yes. You have the legal right to refuse the search if you choose. The officer cannot arrest you simply for refusing to consent to a search of your vehicle. In some limited cases, however, your car can be searched without your permission or a warrant, as long as the police officer has probable cause to believe that you have committed a crime. Even if you think that what the officer is doing is illegal, do not resist. If the officer illegally obtains evidence against you, it cannot be used at trial.
