United States
The National Highway Traffic Safety Administration has published safety guidelines in the United States which apply to vehicles operating in the 20–25 mile-per-hour speed range. Low-speed vehicles are defined as a four-wheeled motor vehicle that has a gross vehicle weight rating of less than 3,000 pounds (1,400 kg) and a top speed of between 20 to 25 mph (32 to 40 km/h).
Nearly all 50 states allow LSVs, also called NEVs, to drive on their roads where the speed limit is 35 mph or less. Either they follow FMVSS500 (25 mph top speed on 35 mph limit roads), or make their own more aggressive law. Because of federal law, car dealers cannot legally sell the vehicles to go faster than 25 mph (40 km/h), but the buyer can easily modify the car to go 35 mph (56 km/h). However, if modified to exceed 25 mph (40 km/h), the vehicle then becomes subject to additional safety requirements.
These speed restrictions, combined with a typical driving range of 30 miles (48 km) per charge and a typical three-year battery durability, are required because of a lack of federally mandated safety equipment and features which NEVs can not accommodate because of their design. To satisfy federal safety requirements for manufacturers, NEVs must be equipped with three-point seat belts or a lap belt, windshield wipers are not required, running lights, headlights, brake lights, reflectors, rear view mirrors, and turn signals. In many cases, doors may be optional, crash protection from other vehicles is partially met compared to other non motorized transport such as bicycles because of the use of seat belts. In 2011, a Time magazine article concluded that the lack of passenger safety protection made most LSVs unfit for city driving, despite their excellent maneuverability.

Famous quotes related to united states:
“The United States have a coffle of four millions of slaves. They are determined to keep them in this condition; and Massachusetts is one of the confederated overseers to prevent their escape.”
—Henry David Thoreau (18171862)
“An alliance is like a chain. It is not made stronger by adding weak links to it. A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
—Walter Lippmann (18891974)
“The parallel between antifeminism and race prejudice is striking. The same underlying motives appear to be at work, namely fear, jealousy, feelings of insecurity, fear of economic competition, guilt feelings, and the like. Many of the leaders of the feminist movement in the nineteenth-century United States clearly understood the similarity of the motives at work in antifeminism and race discrimination and associated themselves with the anti slavery movement.”
—Ashley Montagu (b. 1905)
“Fortunately, the time has long passed when people liked to regard the United States as some kind of melting pot, taking men and women from every part of the world and converting them into standardized, homogenized Americans. We are, I think, much more mature and wise today. Just as we welcome a world of diversity, so we glory in an America of diversityan America all the richer for the many different and distinctive strands of which it is woven.”
—Hubert H. Humphrey (19111978)
“Madam, I may be President of the United States, but my private life is nobodys damn business.”
—Chester A. Arthur (18291886)
