School Bus Drivers’ Day is observed annually on the fourth Tuesday in April. This year it falls on April 22. School Bus Drivers’ Day originated in California. After it had been celebrated there informally for a while, the California legislature declared the day official. In 2009, they created the day to draw special public attention to school bus drivers in California for their enduring and exceptional contributions to students. The holiday seems to have spread after being established in the state to be commemorated casually.
