For the first time decades, Iowa is taking the brakes off its 55 mph speed limit.
Gov. Kim Reynolds signed Senate File 378 into law on June 1, effectively raising the default speed limit in areas where no speed limit is posted to 60 miles an hour.
Starting on Wednesday, July 1, the Iowa Department of Transportation will place temporary "60" overlays on existing signs to update the speed limit until the signs are due for normal replacement.
But that doesn't mean the limit will change everywhere, a state highway official warned. The state may keep the speed limit at 55 mph or lower in some places if it deems it unsafe to raise it.
