Spray produced by large trucks in wet weather creates poor visibility for all drivers. This condition is of great concern, as reduced vision caused by spray can jeopardise drivers’ safety. To address this problem, several truck and equipment manufacturers have developed aerodynamic truck designs and aftermarket devices to suppress spray. In past years these devices have been evaluated to determine their effectiveness in limiting spray. However, in recent years new devices have been developed that have not had their spray suppression capability evaluated. This peer-reviewed report documents two experiments intended to examine the effectiveness of several commercially available spray devices that can be attached to large trucks to reduce splash and spray during wet weather conditions.
