Not Legal Advice: To get a temporary tag, the driver has to bring one of either the certificate of title, manufacturer's statement of origin (MSO), bill of sale, notice of sale or a Missouri application for title and license. Unless the driver has an MSO, the driver must also provide a safety inspection; all drivers need a current insurance identification card or proof of insurance. There is also a $7.50 permit fee, plus a $3.50 processing fee, as of 2011.
In Missouri, temporary permits, or tags, are valid for up to 30 days from the date of purchase, and drivers can only obtain one permit per vehicle.
Every time you drive your car or park on a city street, there's a good chance your license plate is being photographed. Technology is being used to scan license plates today. With each scan, a photograph is taken of the license plate and the vehicle's GPS coordinates are recorded to pinpoint its location.
