Police have charged Grundy with habitual impaired driving, which is a felony. He has three DWI convictions and a fourth case pending.
Authorities say Grundy's blood alcohol content was .16, twice the legal limit.
Grundy was a standout point guard for NC State from 1998 to 2001, when he was named to the 1st Team All-ACC.
Grundy is scheduled to appear in court Thursday.
