Erie County sheriff’s road patrols made two DWI arrests early Saturday morning, including one based on a complaint that a driver had passed out in the drive-thru lane of a fast-food restaurant.

Sheriff’s Deputies Bradley Girdler and Jason Clark responded to that complaint at the Mighty Taco drive-thru on Grand Island at about 1 a.m. By the time they reached the scene, the driver had left the area, but the deputies later stopped him as he drove at a high rate of speed, according to police reports.

Joseph F. Kaefer Jr., 45, of Grand Island, was charged with aggravated driving while intoxicated, after a breath test revealed a blood-alcohol level of 0.19 percent, deputies said.

At about 3 a.m., deputies stopped a vehicle for failing to stay in its lane on Route 219 in the Town of Concord. After determining that the driver had a suspended license, Nathan D. Kent, 26, of Great Valley, was charged with DWI, aggravated unlicensed operation, driving with a suspended registration and marijuana possession, according to police reports.
