PS is the most widely used resin material for thermoforming. High-impact polystyrene (HIPS) is the most widely used, being employed largely in the packaging areas, including disposables (foam drinking cups, lids, lunch trays, and food service containers), packaging for medical devices, and food packaging (meat and poultry trays, egg cartons, dairy and delicatessen containers, and barrier packages). ABS is thermoformed to produce more durable articles such as refrigerator inner door liners, recreational vehicle and boat parts, automotive panels, picnic coolers, and luggage exteriors. HDPE is used in the manufacture of pickup truck liners, golf cart tops, and sleds. Crystallized PET is used in the thermoforming of food trays that can be heated in a microwave or regular oven. Frozen-food oven-friendly trays are made from coextruded polycarbonate–polyetherimide. Polycarbonates and poly(methyl methacrylate) are thermoformed to produce skylights, windows, tub and shower stalls, and outdoor display signs. PVC is used in the production of blister packaging of pharmaceuticals, foods, cosmetics, and hardware.

Georgia statutes further define golf carts as motor vehicles to limit their use on public pathways, streets, and highways, therefore additional safety regulations related to their recreational use have not been enacted (Georgia Department of Public Safety). The Georgia Department of Public Safety defines a golf cart as a motorized vehicle used to transport one or more people to play golf on the designated golf course, with an average speed of less than 15 miles per hour. In 2013, Georgia passed a new law that allowed local government to determine where golf carts are to be used with the proper signage (Richman Law Firm). The city seat of our county, Gainesville, is updating its city ordinances to allow "personal transportation vehicles" on city streets. Safety equipment, such as hip restraints and hand holds, or a combination thereof is mandated as well as the rearview mirror, horn, tail lamps, headlamps, and power switches. Golf cart style personal transportation vehicles will be able to operate on any city street that has a maximum speed limit of 35 mph. There will also be designated intersections where these vehicles may cross state routes.

Golf carts (GCs) are engineered to be used primarily on golf courses but are increasingly being used for transportation on roadways within the US communities (Passaro et al. 1996). With speeds limited to 20 mph, they are commonly considered safe and economical, and an environmentally friendly means of transportation, and are thus not subject to the state and federal safety regulations that apply to motor vehicles.
