A domino effect of collisions affected five cars on Saturday morning during the snow storm that produced low visibility on Highway 195 near Colton.

A Pullman School District school bus was stopped in the southbound lane, just south of Johnson Road. Three more vehicles were stacked behind the school bus, also stopped.

A Spokane Valley driver, Sydney Bebee, 44, came in from behind, smashing into one vehicle, pushing it across the northbound lanes and then into the ditch. Bebee then struck another vehicle and then another, pushing it into the school bus. Bebee's truck finally came to a rest against one of the vehicles already in the ditch.

WSP says the 12 students and teacher were not injured during the incident. The driver and passenger of one vehicle, Frances M. Bakke, 35, of Kennewick, and Nathan Bakke, 35, of Kennwick as well, were injured during the crash and transported to Pullman Hospital in an ambulance.

Bebee's truck was total and towed during the incident. She was cited for driving too fast for conditioned.

Seasonal weight restrictions are being placed on some Spokane County roads starting next Monday. The restrictions limit the size and weight of vehicles that can travel on those specific roads.

The restrictions are being put into place to reduce roadway damage and infrastructure before the spring.

The Sheriff's Office says they're going to allow a two-day education period to the public before they begin enforcing the new regulations on Wednesday, February 15th. After that, all violations become a $411 fine.
