There is a HIGH number of unregistered/uninsured drivers in Providence. Their cars stick out (often no front license plate, expired registration sticker, expired inspection sticker, etc.) If you know what to look for, you will see these cars everywhere. When one of these drivers HIT someone they are motivated to run. The Providence police do little / no enforcement on this issue. Many of these drivers may also be unlicensed. This will only change if people talk repeatedly to their city council member (I have) and urge the mayor to have the police enforce.
