The nation’s most disobeyed law is dysfunctional from top to bottom. The speed limit is alternately too low on interstate highways, giving police discretion to make stops at will, and too high on local roads, creating carnage on neighborhood streets. Enforcement is both inadequate and punitive. The cost is enormous. And the lack of political will to do something about it tracks with George Carlin’s famous observation that everybody going faster than you is a maniac and everybody going slower than you is an idiot. The consensus is: Enforce the speed limit. But not on me, please. Because while it would be nice to save 10,000 lives a year, it sure is fun to drive fast.
It is as strange as cigarettes on airplanes or dating ads in newspapers to think that between 1974 and 1995, the United States maintained a national speed limit of 55 miles per hour in the name of saving lives. It was one of those moments, like the end of the Concorde’s supersonic passenger jet service or the collapse of the Arecibo Telescope, when technology lurched backward.
The 50-state slowdown known as the “double nickel” began in 1973, with President Richard Nixon’s appeal for collective sacrifice. In retaliation for America’s support of Israel in the Yom Kippur War, the coalition of Middle Eastern states known as OPEC decided that fall to stop selling oil to the United States. Prices quadrupled. The president wanted Americans to change their ways: He asked gas stations to close on Sundays and businesses to turn off lighted advertisements. Mayors and department stores dimmed Christmas bulbs nationwide. Daylight saving time went year-round in an effort to use less electric light. Thanks to the lowered thermostat, women were permitted to wear pants in the White House.
And Nixon prompted Congress to implement a national speed limit, for the first time since the Second World War. Then it was to conserve rubber; now, the White House hoped, slower and more fuel-efficient driving would save gasoline.
The lower speed limit did not, in the end, have a significant effect on gas consumption. But the law was retained until the Clinton administration because it appeared to have another welcome consequence: saving lives. In the first six months of 1974, highway deaths fell by 23 percent—a decline widely attributed to the national speed limit. At the urging of the U.S. Transportation Secretary Claude Brinegar, Congress made the 55 mph speed limit permanent.
