SPOKANE, Wash. -

A Spokane school bus was involved in an accident at 9 a.m. Thursday near the intersection of Thurston and Pittsburg on the South Hill.

The school bus hit a mail truck parked on the right side of Thurston. The driver was attempting to slow down while approaching the intersection when the wheels locked up and the bus started sliding.

"Especially when you come off of a decent main arterial that's wet and bare and you come onto a side street, you are still carrying some of that speed that you were used to the speed limits are not appropriate on the side streets they need to be much slower," Spokane Police Officer Nate Spiering said.

A service truck with the school bus company responded to the scene and after it was parked a silver Nissan Xtera struck that vehicle, causing the service truck to roll about 50 yards before it came to rest in the yard of a nearby home.

No one was cited Spiering says when police are dealing with collisions give them space and be careful

"When you have a vehicle parked on the side of the road with the flashers and the overheads going we need to be cognizant of that as well," he said.
