Kim Corothers was on her way to pick her son up from daycare on Tuesday evening when three rocks flew off a dump truck driving past her in the opposite lane.

One was big, about the size of a pumpkin, and it bounced as high as her windshield, right in her path on the Alaska Highway.

She pulled over into the bike lane, and it rolled into the ditch.

The other two, the size of soccer balls, rolled off the road.

“It was scary,” Corothers said in an interview this morning. “I was really rattled. I was kind of in shock after it happened.”

Miraculously, there were no other vehicles on the road at the time, about 5:30 p.m., near the turnoff for the Super A in Porter Creek.

“Somebody was looking out for someone,” Corothers said. “It would have done serious damage.”

In her rearview mirror, Corothers could see the truck didn’t slow down. She thinks the driver wasn’t even aware of what happened.

“Because everything happened so fast, I didn’t identify whose truck it was.”

She didn’t see if the truck had a cover on it.

Whitehorse RCMP Const. Dean Hoogland said this morning police received a complaint about the truck shortly after 5 p.m. Tuesday, and pulled the vehicle over near Two Mile Hill.

The driver was unaware of the falling rocks.

Hoogland said its back tailgate was open, and after speaking with police, the driver closed it.

The company, which Hoogland could not identify, cleaned up the rock debris.

No charges were laid, although he said there could have been.

Allowing a load or part of a load to fall off a vehicle is a chargeable offence under the Motor Vehicles Act.

“The officer used his discretion and decided that no charge would be warranted,” Hoogland said.

Police received no reports of any vehicles being hit by the falling rocks.
