Make sure your rear license plate is clean and readable. In order to recognize your vehicle, RapidScreen’s testing equipment must be able to read your license plate. Dirty or damaged plates, trailer hitches, bike racks and other obstructions can make your plate unreadable to our camera—resulting in an invalid reading.
