No one was hurt Wednesday morning when a school bus that was not transporting students and two other vehicles collided Wednesday morning at a busy Black Rock Turnpike intersection, according to Fairfield firefighters.

The crash took place shortly before 8 a.m. when the bus, traveling east on Burroughs Road, collided with an Acura and Jeep Liberty.

The Jeep, driven by Marina Walkuski, 63, of Stamford, was traveling south on Black Rock Turnpike when police said she failed to stop for a red traffic light and struck the Acura, which was crossing Black Rock Turnpike and headed west on Burroughs Road. The impact caused the Acura to strike the right front tire of the school bus, according to the police report.

Walkuski was issued an infraction for failure to obey a traffic light.

The Fire Department's Engine 2, Ladder 2 and Car 3 were dispatched to the scene.

The school bus was occupied only by the driver, and none of the operators had to be extricated from their vehicles.

A paramedic from AMR Ambulance checked the drivers and all three declined further medical attention,.
