Radar Speed (Feedback) Signs – FAQ
What is a Radar Speed Sign?
Radar Speed Signs are portable traffic safety devices that display the speed of approaching vehicles using radar technology. The real-time display reminds drivers of their speed and encourages voluntary compliance with the posted speed limit.
Why does Clackamas County use Radar Speed Signs?
Clackamas County Traffic Engineering uses Portable Radar Speed Signs as part of a broader, data-driven approach to traffic safety. The signs support education and awareness, particularly on county roads where traditional traffic calming measures may not be feasible due to traffic volumes, speeds, roadway function, or emergency response needs.
Do Radar Speed Signs issue tickets or take photos?
No. Radar Speed Signs are not enforcement devices. They do not issue citations, take photographs, or collect license plate or personal information. Counties in Oregon are not permitted to use photo radar for enforcement outside of city limits.
Do the signs collect data?
Yes. Radar Speed Signs may collect anonymous traffic data, such as vehicle speeds and volumes. This information helps Traffic Engineering staff evaluate speeding concerns and assess the effectiveness of safety measures,
Can residents request a Radar Speed Sign?
Yes. Radar Speed Sign locations are identified based solely on resident-submitted requests. Requests are submitted through the County’s online Traffic Concern Form and are added to a working list of potential locations.
Traffic Engineering staff review requests to confirm roadway eligibility and to prioritize installations based on safety considerations and sign availability. Signs are rotated monthly.
What should I do if I notice a damaged or malfunctioning sign?
Damaged or malfunctioning signs should be reported through the County’s Road Concerns Form so Traffic Engineering staff can investigate and address the issue.
