FMVSS 220 Standard Test Method for School Bus Rollover Protection

Federal Motor Vehicle Safety Standard 220 (FMVSS 220), Research was conducted primarily using a numerical study on components supplemented by experimental validation tests and full-scale rollover tests.

This test was conducted to identify the most important structural components that affect the response of the bus. The results from this study show that the final outcome of the crash-resistance assessment of the chosen paratransit bus depends on the choice of the assessment standard. Although this test is used for the same purpose for roof integrity assessment, its results are different and may lead to different results.

The FMVSS 1998 standard, entitled School bus rollover protection (US DOT, 220), is widely used in the United States to evaluate the resistance of a wide variety of buses to rollover collisions. It is also voluntarily used to test smaller, paratransit (cut) buses for the integrity of their structures in the absence of a specific standard.

Its semi-static nature provides an attractive, easy-to-perform test that ensures good reproducibility of results. However, this procedure may not be the best choice for evaluating the dynamic behavior of a bus during a rollover accident.
