who started the red scare in the united states in the 1950s
Red Scare The second Red Scare occurred after World War II (1939–45), and was popularly known as "McCarthyism" after its most famous supporter, Senator Joseph McCarthy. McCarthyism coincided with increased popular fear of communist espionage consequent to a Soviet Eastern Europe, the Berlin Blockade (1948–49), the Chinese Civil War, the confessions of spying for the Soviet Union given by several high-ranking U.S. government officials, and the Korean War.
Turn on red Right turns on red are permitted in many regions of North America. While Western states have allowed it for more than 50 years;[citation needed] eastern states amended their traffic laws to allow it in the 1970s as a fuel-saving measure in response to motor fuel shortages in 1973. The Energy Policy and Conservation Act of 1975 required in ยง362(c)(5) that in order for a state to receive federal assistance in developing mandated conservation programs, they must permit right turns on red lights.[2] All 50 states, the District of Columbia, Guam, and Puerto Rico have allowed right turns on red since 1980, except where prohibited by a sign or where right turns are controlled by dedicated traffic lights. (On January 1, 1980, Massachusetts became the last US state to allow right turns on red.[3]) The few exceptions include New York City,[4] where right turns on red are prohibited, unless a sign indicates otherwise.
