The report discusses spray protectors to reduce the obscuring of view of following drivers by spray and debris thrown up by the vehicle wheels. The objective of this project was to obtain data from a series of road tests on the amount of spray contributed by each wheel from a truck tractor and semi-trailer combination vehicle, and a truck transport when tested under variable conditions of vehicle loading, tire wear, road conditions, and road moisture. Experimental testing was conducted on two different road surfaces using two trucks with new tires and worn tires, loaded and unloaded, under road moisture conditions of heavy water and light water.
