Eight tests are performed on the buses: Maintainability (includes accessibility), Reliability, Safety (includes brake performance), Performance, Structural Integrity and Durability, Fuel/Energy Economy, Noise (interior and exterior), and Emissions.
For Colorado Rack compliance, the test requires that two prescribed cycles of load be applied to the bow immediately above the passenger windows. During testing, the bus structure cannot deflect more than 5-1/8 inches when measured diagonally, and all emergency exits must be functional after the test.
During the test, a school bus rollover is simulated with an 8-inch diameter pole impacting the roof with enough force to cause the roof to bend into the passenger compartment between 8 and 10 inches. Throughout this test, the body panels cannot separate. While the test was developed for the state of Kentucky, it is utilized by multiple North American states and provinces as a required specification.
