R.I. Gen. Laws § 31-10-17: Release from liability.

Any person who has signed the application of a minor for a license may later file with the division of motor vehicles a verified written request that the license granted to the minor be cancelled. On receipt of the request the division of motor vehicles shall cancel the license of the minor and the person who signed the application of the minor shall be relieved from the liability imposed under this chapter by reason of having signed the application on account of any subsequent negligence or willful misconduct of the minor in operating a motor vehicle.
