A great car kit from DSV - 3 standard signal triangles. These signal triangles are U.S. Department of Transportation approved and safety standard. They are made of durable orange-colored plastic with wide reflective stripes around the edges that are clearly visible both day and night. Thanks to the stable non-slip base, they stand securely on the road without tipping over from gusts of wind or passing traffic. The 17 x 17 inch triangles are sized to be noticed from afar. They fold up quickly and easily for compact storage in the included bag.
