Ordered that the order is affirmed, with costs.
"Pursuant to the unambiguous language of Vehicle and Traffic Law § 1229-c (8), the appellant[s] [are] expressly precluded from seeking to defend against liability based upon the claim that the children were not [wearing safety belts or] strapped in . . . child-car seats at the time of the accident" ( Boyd v Trent, 297 AD2d 301, 302; see General Obligations Law § 3-111; Spier v Barker, 35 NY2d 444; Martinez v Novin, 303 AD2d 653). Accordingly, there being no issue of fact raised in opposition to the plaintiffs' prima facie establishment of their right to judgment as a matter of law, the Supreme Court properly granted the plaintiffs' motion for summary judgment on the issue of liability ( see CPLR 3212).
