Assembly Bill 1840Committee on Budget. Education financehas been signed by Governor Brown for the extension of compliance of the child safety alert system.


  With respect to Section 34 of this act(see attached):

(a) It is the intent of the Legislature by authorizing the extension for compliance with the child safety requirements initially established by Chapter 721 of the Statutes of 2016 (Senate Bill 1072 of the 2015–16 Regular Session) to provide a sufficient timeline to successfully install child safety alert systems in all applicable vehicles as required by Section 28160 of the Vehicle Code to ensure the safety of all pupils and youth being transported.

(b) It is further the intent of the Legislature, by providing this extension, to strongly encourage school districts, county offices of education, charter schools, private schools, and other entities to prioritize the installation of child safety alert systems on vehicles that transport individuals with exceptional needs, as defined in Section 56026 of the Education Code, as their safety continues to be a top priority for the Legislature.

 (c) Additionally, as public safety remains a top priority for the Legislature, it is further the intent of the Legislature to only provide this extension on a one-time basis to ensure that child safety alert systems are properly installed on all applicable vehicles pursuant to Section 28160 of the Vehicle Code and pupils and youth are transported in the safest manner.
