Heavy Vehicle Splash and Spray Suppression
In 1988, NHTSA terminated rulemaking requiring splash and spray suppression devices on large trucks. The agency determined at that time that there was no available technology demonstrated that would consistently reduce splash and spray to an extent that would improve visibility. In 1999 a study was conducted and a Report to Congress [ add link to report ] was prepared to identify and evaluate the technological advancements in heavy vehicle splash and spray suppression devices since the agency’s last report to Congress in March 1994.
