National Traffic and Motor Vehicle Safety Act
-
What is the National Traffic and Motor Vehicle Safety Act?
The National Traffic and Motor Vehicle Safety Act, passed in 1966, mandated that auto manufacturers meet safety standards protecting the public from unreasonable accident risks related to automobile design, construction, or operation.
The act was spurred by a series of events that focused national attention on auto safety, including Ralph Nader's 1965 book, Unsafe at Any Speed, which highlighted alleged defects in the Chevrolet Corvair. Congressional hearings revealed that General Motors had unsuccessfully attempted to find personal dirt on Nader, generating popular support for federal legislation holding auto manufacturers responsible for their products' safety.
The act led to mandated safety features like seatbelts and shatterproof windshields, a drop in traffic deaths, and the creation of the National Highway Traffic Safety Administration (NHTSA).

When was the National Traffic and Motor Vehicle Safety Act passed?
In 1966, the U.S. Congress passed the National Traffic and Motor Vehicle Safety Act, which President Lyndon Johnson signed into law. This legislation mandated that auto manufacturers implement safety standards to protect the public from unreasonable accident risks related to automobile design, construction, or operation. A related act, the Highway Safety Act, addressed nonoperational safety factors like highway design and established the National Highway Safety Bureau (NHSB), which became the National Highway Traffic Safety Administration (NHTSA) in 1970, to enforce uniform safety standards.

Why was the National Traffic and Motor Vehicle Safety Act created?
The National Traffic and Motor Vehicle Safety Act was created in 1966 because traffic fatalities were rising, and the public was increasingly concerned about traffic accidents. Ralph Nader's book Unsafe at Any Speed (1965) criticized the auto industry for prioritizing style over safety, increasing public awareness. Congressional hearings revealed that General Motors was attempting to discredit Nader, generating support for federal legislation holding auto manufacturers responsible for safety. The Act aimed to protect the public from unreasonable accident risks related to vehicle design, construction, or operation.

What kinds of vehicle safety standards did the Act introduce?
The National Traffic and Motor Vehicle Safety Act of 1966 was U.S. legislation that required auto manufacturers to institute safety standards protecting the public from unreasonable accident risks caused by automobile design, construction, or operation.
During the decade after the Act's passage, mandated standards included shoulder-lap belts, collapsible steering columns, strengthened door latches, shatterproof windshields, and protective dashboards.
The Act also led to product safety lawsuits, recalls, and lower traffic death rates. Additional regulation in 1975 added a 10-year schedule of improvements to new cars' fuel efficiency standards.

How did the Act change the way cars were designed and built?
The National Traffic and Motor Vehicle Safety Act of 1966 was U.S. legislation that required auto manufacturers to meet safety standards protecting the public from unreasonable accident risks related to a car's design, construction, or operation.
Following the Act, safety mandates led to features like shoulder-lap belts, collapsible steering columns, strengthened door latches, shatterproof windshields, and protective dashboards becoming standard. The Act also spurred product safety lawsuits and vehicle recalls. Later regulations in 1975 added a 10-year schedule of improvements to new cars' fuel efficiency standards.

What impact did the National Traffic and Motor Vehicle Safety Act have on road safety in the United States?
The National Traffic and Motor Vehicle Safety Act of 1966 mandated safety standards for auto manufacturers to protect the public from unreasonable accident risks caused by vehicle design, construction, or operation. This act, along with the Highway Safety Act, led to the creation of the National Highway Safety Bureau (NHSB), which was succeeded by the National Highway Traffic Safety Administration (NHTSA) in 1970.
The legislation was spurred by rising traffic fatalities and public concern, notably highlighted by Ralph Nader's book Unsafe at Any Speed. Resulting safety standards included features like seat belts, collapsible steering columns, and shatterproof windshields. These measures led to numerous product safety lawsuits, recalls, and significantly reduced traffic death rates. By 1998, NHTSA estimated that seat belts alone saved at least 10,000 lives annually.

National Traffic and Motor Vehicle Safety Act, U.S. legislation that required automobile manufacturers to institute safety standards to protect the public from unreasonable risk of accidents occurring as a result of the design, construction, or operation of automobiles. A closely related legislative act, the Highway Safety Act, included nonoperational safety factors, such as highway design, and it empowered a new agency—the National Highway Safety Bureau (NHSB), which was in 1970 succeeded by the National Highway Traffic Safety Administration (NHTSA)—to mandate uniform safety standards. Both acts were passed by Congress and signed by Pres. Lyndon Johnson in 1966.
By 1965, automobile accidents had become the leading cause of death of Americans under age 44. Both government and manufacturers had largely ignored the issue, though, until a series of events focused national attention on automobile safety and culminated in litigation and automobile recalls in the years following the establishment of the NHSB and NHTSA. A relatively obscure lawyer named Ralph Nader emphasized the issue of automobile safety in his 1965 book Unsafe at Any Speed, which focused on the alleged defects of the Chevrolet Corvair. Extensive congressional automobile safety hearings the following year, chaired by Senator Robert Kennedy, grabbed the spotlight when they revealed that General Motors, the manufacturer of the Corvair, secretly employed detectives in an unsuccessful attempt to find personal “dirt” on Nader. Those hearings created the necessary popular support to pass a federal law that made automobile manufacturers responsible for the safety of their products.
During the next decade, lifesaving shoulder-lap belts, collapsible steering columns, strengthened door latches, shatterproof windshields, and protective dashboards became the mandated standard. Those new legal requirements led to a record number of product safety lawsuits and many product recalls and, ultimately, to significantly lower traffic death rates. Additional regulation was added in 1975 with a 10-year schedule of improvements to the fuel efficiency standards of new cars. Critics from the automobile industry and many free market advocates decried such requirements as overly bureaucratic edicts that restricted consumer freedom and were far too costly for industry.
A 1985 article by Nader in The New York Times asserted that those regulations had already saved more than 150,000 lives and cited a government report that motorists had also saved “a cumulative $90 billion in transportation costs since 1975 from improvements in fuel economy.” Many consumer advocates believed that those savings had largely resulted from design and engineering changes that Detroit automakers would never have done without pressure from the NHTSA. Even Henry Ford II in 1977 allowed that the first wave of NHTSA standards had advanced car and highway safety, fuel efficiency, and pollution controls. By 1998 the NHTSA estimated that seat belts alone saved at least 10,000 lives a year.
After the heady early years of the agency’s existence, NHTSA regulatory programs slowed considerably, beginning in the late 1970s. Mandates for the second wave of engineering advances such as the air bag were delayed for more than a decade by successive congresses that were increasingly skeptical about regulation and more susceptible to the auto industry’s very extensive lobbying activities. In the middle of the first decade of the 21st century, however, significant increases in fuel prices, coupled with large numbers of fuel-inefficient sport-utility vehicles, prompted a renewal of congressional mandates for increased fuel standards.
