The latest way to stop speeders in South Florida? Trick them with an optical illusion.

The “magic” involves marking a road with hash marks, similar to those on a football field. With the lines spaced at gradually closer intervals, drivers get the illusion they’re going faster than they really are — and tap the brakes, traffic engineers say.

The technique for the first time will be tested in Fort Lauderdale later this year or early next year. It will start on a curving stretch of Andrews Avenue and if it works, it may be used on other roads in Broward and Palm Beach counties.
