During the week of July 15-19, 1974, a series of tests was run at Madras, Oregon to evaluate a number of devices designed to suppress the spray created by trucks on wet roads. The tests, supervised by members of the Western States Subcommittee on Splash and Spray, were documented with movie film that covered the devices and tests. Good correlation resulted between the spray data obtained with a photometer set up at the test site and the data obtained by performing densitometer analyses of photographic negatives taken at the test site. The spray data determined the relative effectiveness of the various experimental spray suppressor devices, showing that none of the devices tested reduced the road spray a significant amount. The best of the four devices reduced the spray 15 to 20 percent relative to the standard bogie vehicle.
