This paper is a extension and replication of “Providing driver’s licenses to unauthorized immigrants in California improves traffic safety” paper by Hans Lueders, Jens Hainmueller and Duncan Lawrence published in 2017 that examines the short-term effects of California’s Assembly Bill 60 (AB60) implemented in 2015. The law legalizes driving for unauthorized immigrants in California.
