Frequently Asked Questions
Not exactly. A 'radar trap' specifically uses radar technology to detect speed, often operated by an officer with a radar gun. A 'speed camera' is a fixed or mobile camera that may use radar, lasers, or sensors embedded in the road. In everyday UK English, 'speed camera' is the umbrella term.
Yes, informally. For example, 'The police were radar-trapping on the highway.' It's more common in American English.
Obey the posted speed limit. Drivers also use radar detectors (illegal in some regions) or community-based GPS apps that share locations of known enforcement spots.
No, it is considered informal to neutral. More formal terms are 'speed enforcement zone', 'traffic enforcement camera system', or 'automated speed measurement device'.
