The Effects on Insurance Costs of Restricting Undocumented Immigrants' Access to Driver Licenses

Proponents of issuing driver licenses to undocumented immigrants argue that the number of uninsured motorists and car accidents would decrease, thus improving public safety and lowering costs associated with car insurance. This study gives an overview of competing cost reduction and public safety arguments and examines the issues surrounding undocumented immigrants and driver licenses. It empirically assesses the effect on the average cost of auto insurance of restricting undocumented access to legal driving documents. We use a fixed effects model for panel data to test the effects on real average insurance expenditures of restricting undocumented immigrants' access to driver licenses, while controlling for other relevant factors suggested in the literature. Our main finding is that on net such restrictions raise the average annual cost of auto insurance by an estimated $17.22 ($2009) across states that have enacted such restrictions.
