IMPROVED VISIBILITY FOR SCHOOL BUSES DURING ADVERSE WEATHER. VOLUME I

The objectives of the program were to develop realistic performance requirements and compliance test procedures which could be used by school bus manufacturers as well as testing agencies to assure that school bus defogging equipment will meet vehicle drivers' visual requirements for forward, sideward, and rearward views under conditions of fog formation on the interior surfaces of the vehicle's glazing during adverse weather. Several buses, including Type I, Type II, and Transit-type buses, were tested utilizing normal engine operation and also with an auxiliary hot water system. Results of these tests were used in preparing a detailed defogging test procedure and recommended performance requirements.
