From Senate Bill 262 (2008) now codified at Del. Code Title 21 § 2710 and § 6104:

This Bill addresses several areas in the motor vehicles statute regarding who can “sponsor” a foster child who wishes to obtain a driver’s license.  The Bill also addresses the issue of liability for the “sponsor” should they sign.  First, the Bill clarifies the current statute to specifically allow a Division of Family Services case worker or foster parent to sign for a foster child to obtain a driver’s license in Delaware.  Second, the Bill specifically exempts a Division of Family Services caseworker or foster parent who sponsors a foster child or loans a vehicle to such foster child from liability should that foster child cause damages resulting from the foster child’s negligence.
