 The 1990 death of six-year-old Elizabeth "Betsy" Anderson, in Washington State, led to the installation of school bus crossing arms, also referred to as "Betsy Bars" or "Betsy Gates" on all Washington state school busses by 1992.The crossing arms, when extended, require students to cross at least 5 feet in front of the bus.In Manitoba, Canada, provincial school buses have been required to have an extendable safety arm mounted on the bus since a seven-year-old boy died in 1996 in St. Norbert, after getting off his school bus.
