An independent review will examine safety policies and performance under the Boston Public School's transportation contract with Transdev, which manages 750 school bus drivers in the city.

The investigation will include a review of existing safety policies and performance, including under the bus driver collective bargaining agreement, and make recommendations to strengthen safety measures.

Boston Mayor Michelle Wu has ordered an independent investigation of the public school district’s contracts with its transportation provider, Transdev, after a bus driver with lapsed credentials and a spotty driving record killed a 5-year-old boy.
