You should never consent to letting anyone search your vehicle. Never volunteer to give a police officer the keys to your car. Never unlock car doors or open doors, the glove box or trunk of your car for a police officer. If you do, your actions will most likely be interpreted to mean that you consented to the search of your vehicle. A police officer will request your permission to search your vehicle in order to look for weapons, drugs, evidence of DUI, or any other criminal activity. If the officer finds any of the above, the officer will arrest you and you will end up in jail. Advise the officer (as politely as possible) that your lawyer advised you to never consent to the search of your vehicle.
