A Lockport woman was charged with driving while intoxicated and speeding Sunday afternoon on the Kensington Expressway, state police said.

Chloe Pettit, 20, was arrested after being pulled over at 5:10 p.m. by Trooper Ronald Ensminger, who said he clocked her driving 79 mph in a 55-mph zone.

Pettit failed several roadside sobriety tests, and her blood-alcohol content was measured at 0.11 percent in a breath test at the barracks in Clarence, Ensminger said.
