Let’s learn about a law in America today in our homeschools! On this day in American history – January 2, 1974 – President Richard Nixon signed a law that pushed states to adopt a nationwide 55 mph speed limit law during the energy crisis.
In this 55 mph speed limit law mini lesson, your students will learn the “why” behind the national limit and practice a key skill for understand civics: explaining how state laws and federal laws are made. Also learn how these laws affect our everyday lives here in America.

Background on the 55 mph Speed Limit Law
In the early 1970s, America faced an energy crisis and fuel shortages. To help conserve gasoline, Congress passed the Emergency Highway Energy Conservation Act, and it became national policy for states to set a maximum speed limit of 55 mph in order to maintain certain federal highway funding.
This 55 mph speed limit law is an example of how the federal government can influence state decisions—especially when funding (money!) is involved.
On January 2, 1974, President Richard Milhous Nixon imposed the 55 miles per hour speed limit. Since it was a federal law, it applied to all of the United States.

2.) Write a paragraph giving your opinion: Do you think the 55 mph speed limit is fair to U.S. citizens? Why or why not?
3.) Look up your state’s current speed limits. Are any still 55 mph? To what types of roads or highways does the limit apply?
