RapidScreen Roadside Testing

RapidScreen roadside testing offers motorists of well-maintained, clean-running vehicles the opportunity to Skip the Trip to an emissions testing station.

RapidScreen data collection units (either housed in white vans or small green boxes) collect emissions-related data as vehicles are driven by them. The collection units are positioned at pre-determined, state-approved sites on highway on-ramps throughout the Front Range. As a vehicle passes the RapidScreen unit, a camera captures an image of the vehicle and license plate, and a process using infrared and ultraviolet light beams collects and measures the vehicle's emissions output. If the vehicle registers clean, this data is then matched to vehicle registration records, and a 'RapidScreen' message is added to the Vehicle Registration Renewal postcard alerting the driver that they have, 'Passed Roadside Emission.'   

RapidScreen roadside testing units are rotated regularly to collect data from as many vehicles as possible. Access our RapidScreen Locations for the current and upcoming weeks to find unit locations.
