ALBANY – A municipal parking lot is akin to a public highway in that governments must receive prior warning of dangerous conditions before they can be held liable for injuries suffered by users of the facilities, a divided Court of Appeals held yesterday.

The state’s high court decided 4-3 in Groninger v. Village of Mamaroneck, 85, that the icy Westchester County parking lot in which plaintiff Margaret Groninger slipped and fell served the “functional purpose” of being a “highway” under various state laws, including Village Law §6-628 and CPLR 9804.
