Absolutely not! Never consent to a search of your vehicle when you get pulled over for a DUI (driving under the influence). If the police want to search your car, they can do so with the aid of a trained dog which can search for drugs. The search of your vehicle is only valid IF they can get the dog to the scene within the same time period as it would take for the police to write a traffic ticket. This time has been determined by case law to be about 20 - 30 minutes. If it takes longer, which it usually does, then anything found as a result of the search will be suppressed and unavailable for the State to be used against you at your trial. If you are arrested for DUI, they will probably search your car after it's towed for "inventory" purposes and any contraband they find will be used against you, but never consent or it will be very difficult to suppress anything they find in a DUI or drug arrest.
