The National Highway Traffic Safety Administration (NHTSA) has measured spray suppression capabilities of various spray suppression systems for tractor-trailer trucks using over-the-road tests. Photographic techniques were used to quantify the size of the spray clouds. A statistical technique was used to determine whether the spray clouds generated by van type tractor-trailers equipped with spray suppressant devices is indeed less than the spray clouds generated by the same van type tractor-trailers not equipped with spray suppressant devices.
