Like most safety related vehicle products, such as auto seat belts and auto airbags, the S-1 Gard is designed to reduce, but not eliminate the likelihood and severity of serious injuries and the incidence of fatalities resulting from accidents involving pedestrians and bicyclists impacting the right rear wheels of transit buses. In virtually all impacts between persons and buses, some weighing 20 or more tons, bodily injury of varying degrees of severity will likely result. Even a properly installed and functioning S-1 Gard will inflict injuries, some serious, when performing its task of preventing contact with the rear wheels, which would inflict more severe injuries or death.

The S-1 Gard makes no warranty, representation, express or implied that the device will eliminate injuries of any degree. In fact, in some rare incidences serious injuries may result from a "rolling" effect, which may occur should a person be so far under the bus that articulated portion of the S-1 Gard is unable to deflect them from under the vehicle. The S-1 Gard is designed to minimize injuries to person going under the vehicle in front of the S-1 Gard. Pedestrians as well as joggers, persons riding coaster devices, bicyclists and motorcyclists traveling at any speed which collide directly with the side of the S-1 Gard or tire while the bus is turning or traveling straight may be injured or killed because the outer edge of the tire is not protected by the S-1 Gard and in the case of a moving bus, the tire may, in fact, draw the person under the weight of the bus, behind the S-1 Gard protection zone.

Important Safety Notice
to Users of the S1 GARD

Safe operation of the bus is critical to the proper functioning of the S1 GARD as an effective danger-zone barrier in front of the rear wheels.

Unwarranted acceleration into right turns, such as those that penetrate pedestrian cross walks may cause the chassis of the bus to lift from the ground on the right, increasing the gap between the bottom of the GARD and the ground.

This increases the likelihood of a person or body part going under the S1 GARD and impacting the rear wheels.
