Portable rumble strips are intended to improve both worker and motorist safety in maintenance and construction areas. Rumble strips are black, rubbery strips that are 12 inches wide, almost an inch thick and resemble miniature speed-bumps. This safety device is something that can be seen, felt and heard as motorists drive over them. These rumble strips will not damage vehicles and motorists should not drive around them.
