When lead-footed drivers get snagged and ticketed, their downfall might have been passing a speed trap where a cop was using radar or a laser, or maybe the driver passed a speed camera. However, as technology improves traffic enforcement, it is also progressing on the side of the speeder. Now joining the radar detector is crowd-sourced reporting of speed traps, a virtual warning system using the Internet and a mobile app.

This list of the 10 most-active cities for speed traps was compiled by, a community platform  accessed online and via smartphone app, that alerts drivers to traps, hazards and other traffic issues nearby.

Trapster"s list is drawn from the reports of its base of nearly 15 million users. In addition to speed traps and enforcement cameras, "activity" can include road hazards, traffic, school zones, construction zones and locations of roadkill. However, Sean Farrell, product manager for Trapster, says that over 50 percent of the activity reported on Trapster are "live police" speed traps. For each of the following 10 most-active cities, Trapster users entered 3,000 to 4,000 reports in a recent 30-day period.

10. Austin, TX

Law enforcement in the capital of Texas has a reputation for handing out speeding tickets to motorists only one to three miles per hour over the posted limits, says Farrell. "Trapster users have posted on Trapster"s Facebook page that many speed limits drop quickly, and happen to have heavy police ‘speed enforcement" in those areas."
