The four largest rental car companies in the country have agreed to requests made by two senators who are pushing for legislation to prevent rental companies from renting or selling defective vehicles that have not yet been repaired. According to a news report in the Los Angeles Times, Senators Barbara Boxer and Charles Schumer announced the agreement Thursday with Hertz, Avis, Enterprise and Dollar Thrifty, the four most popular rental companies in the United States.

The companies have said they will support the law, which will for the first time put them under federal oversight on recalls. The push for this new law came from Cally Houck, the mother of Raechel, 24, and Jacqueline, 20, who were both killed in a fiery crash in 2004 while returning to the Bay Area after visiting their mother in Ojai.
