In response to petitions by the golf cart industry the National Highway Traffic Safety Administration reviewed its position on low speed vehicles and has taken steps to define a new class of low speed vehicle (LSV) which is exempt from the federal motor vehicle safety standards (FMVSS) that apply to motor vehicles. A new safety standard, FMVSS 100, has been proposed to regulate this new class of vehicle.
The Vehicle Research and Test Center conducted a survey and a series of tests to evaluate the safety and stability of LSVs. Two neighborhood vehicles, the Bombard and the GEM, and one golf car, The Yamaha gasoline powered golf cart, were selected for this study. Testing included 1) measurement of the CG height of the vehicle to determine the Static Stability Factor (SSF) for both unloaded and two passenger configurations 2) measurement of lateral stability in a constant 50 foot radius turn, and 3) straight line braking on both a high coefficient surface and low coefficient surface.
LSV manufacturers raised concerns on the unsuitability of traditional windshield glazings on vehicles that would be used on golf courses as well as highways. Therefore, a short series of tests were conducted to evaluate and compare golf ball impacts on AS-1 and AS-6 glazing (specified in the proposed FMVSS 100). Results of these tests indicate that AS-4 or AS-5 glazing may be a better alternative than AS-6.
