CHICAGO (CBS) — You’d be advised to watch your speed when driving through Chicago, because the city has made the list of the top 10 cities with the most speed traps.

As CBS 2’s Kris Habermehl reports, the National Motorists’ Association has conducted a survey of cities and their speed traps. The organization says Houston has the most speed traps, while Chicago comes in at No. 9.

Houston has a total of 373 speed traps, while Chicago came in with 153.

The National Motorists’ Association opposes speed traps, calling their use am example of “corrupt traffic enforcement.”

“A speed trap exists wherever traffic enforcement is focused on extracting revenue from drivers instead of improving safety,” the group says.

The group also maintains a state-by-state listing of speed traps.

A Yahoo/CNBC report complains about the city’s recent push to use red cameras to catch speeders. Gov. Pat Quinn has already approved legislation authorizing the increased use of speed cameras near schools and parks, but the City Council also must approve the plan.

The report claims that some traffic control devices in Chicago are up to 30 years old, and that local politicians control the speed limits and their enforcements on the interstate system – making it difficult to fight a ticket.
