(AP) — Authorities say no students have been injured in a four-vehicle accident involving a school bus in near Hooper eastern Nebraska.

The accident occurred just before 4 p.m. Tuesday on U.S. Highway 77 near the intersection with old U.S. Highway 275.

Superintendent Jeremy Klein, of Logan View Public Schools, says the bus slowed for railroad trucks, and a three-vehicle collision behind the bus knocked a car into the rear of the bus. He says the bus was carrying 40 students.

Another bus was sent to the scene, but many parents picked up their children there.
