The court exercised its discretion improvidently in denying defendant's motion. There is no evidence that defendant's failure to turn over the trip sheet was willful or in bad faith, or that plaintiff will be prejudiced by the late disclosure, and denying defendant permission to supplement its discovery response by turning over the trip sheet effectively precluded evidence from the only independent eyewitnesses to the accident ( see Scherrer v Time Equities, Inc., 27 AD3d 208 [2006]; Schiavone v Brinewood Rod Gun Club, 283 AD2d 234, 237; Anagnostaros v 81st St. Residence Corp., 269 AD2d 150).
