Student safety is a major concern across the country, and in California, specific measures have been taken to improve air quality so that all residents breathe easier. Student bus transportation programs are required to do their part by following certain rules and regulations regarding idling.

Introduced by California State Senator Tony Mendoza, the Paul Lee School Bus Safety Law was developed after the death of a 19-year-old special needs student who was left on a school bus during a dangerously hot day. This new school bus safety law, scheduled to go into effect prior to the 2018-2019 school year, will require child reminder systems to be installed on all California school buses.
