1973 WINTER TEST REPORT

The Committee on Winter Driving Hazards of the National Safety Council conducted tests on ice and snow covered surfaces to evaluate various equipment, design features and accessories for motor vehicles and various driving techniques. All devices tested are commercially available to the public. Eight projects were selected for the 1973 Program conducted at Stevens Point, Wisconsin, during January 29 and February 9 on a specially graded area which was flooded and frozen. The results showed that an anti-wheel lock device on a tractor semi-trailer proves no substitute for a skilled and prudent man behind the wheel. A good relationship has been established between locked wheel stopping distance and ice surface temperature for 3-axle vehicles about 38,720 loaded pounds and a fair relationship for similar vehicles partially loaded to 28,360 pounds. In terms of reduction of stopping distance on ice the V-bar reinforced chains prove best for traction. Application of salt on 1/8 inch of ice, 700 pounds per two lane mile at 21 degrees F results in melting and elimination of the ice cover. Studded snow tires prove beneficial, as does switching into neutral gear when skidding. Driver-Ed workshops are highly successful. Recommendations of the committee are offered. /SRIS/
