Introducing the Sencillo© Method

Mirror Adjustment Made Simpler

Never intended for use as a mirror adjustment tool, FMVSS 111 was written to ensure school bus manufacturers supply mirror systems that meet a complex set of performance requirements for each of their school bus models. The Sencillo ("Simple")School Bus Mirror Adjustment Method and Grid have been created as a bridge between the manufacturers FMVSS 111 compliance testing and everyday mirror usage thus enabling school bus drivers to properly adjust their mirrors as simply and quickly as possible.
