As evidenced by the number of major metropolitan transit districts retrofitting their buses with the S-1 GARD, bus operators around the country attest that the S-1 GARD is an effective contributor to Danger Zone safety, successfully mitigating catastrophic injuries and fatalities. Accordingly, bicycle advocacy groups are requesting the S-1 GARD.

And the facts back them up: according to the Journal of the National Academy of Forensic Engineers, the prevalent type of accident involving transit buses without the S-1 GARD and individuals is pedestrians or cyclists falling in the path of and/or being pulled under the wheel. Further necessitating such a safety device is pure physics: according to Bernoulli’s principle, a decrease in air pressure between larger object, such as a bus, and a smaller object, such as a bicycle, is created when passing in close proximity, resulting in a force that can pull a bicycle towards a bus.

PTS is proud to have the support of the nation’s leading bicycle advocacy groups – groups like New York’s Transportation Alternatives, the L.A. County Bicycle Coalition, the San Francisco Bicycle Coalition, and the League of American Bicyclists, to name a few.
