South Dakota Road Crews Using Rumble Strips

Wed June 10, 2009 - Midwest Edition

COLMAN, S.D. (AP) South Dakota motorists will hear and feel more bumps on the road this summer.

The state Department of Transportation has started putting temporary rumble strips down in construction zones in hopes of cutting down on the number of rear-end accidents.

Such crashes are common when traffic slows and bunches up in work zones.

The bumps are usually intended to warn drivers of an oncoming stop sign.
