Weather is suspected to have played a role in a dramatic crash in eastern Newfoundland that killed two people in separate vehicles, and left two other people critically injured. 

Four vehicles were involved in the collision, which happened around 4:30 p.m. Sunday about five kilometres east of Clarenville, near the Adeytown exit. 

Nine people in all were involved in the collision, which affected traffic for several hours. 

Police are interviewing witnesses and trying to figure out the sequence of events at the time, although RCMP Cpl. Tony Young said the weather may have been a key factor. 

"We do know that road conditions weren't ideal at the time," he said. 

"There was heavy rain and a lot of water buildup on the road," Young said. "As far as the cause of the accident, we're still not sure."

Fatalities in two vehicles

One person died and another was seriously injured in a car that ended up near the westbound lane. The car was mangled and all its airbags were deployed.

The other fatality and another critically injured person were in an SUV that wound up by the eastbound lane. The front end of the SUV was completely smashed in. 

Four people in a Toyota Tacoma truck, including a child in a car seat, only sustained minor injuries.

The driver of the fourth vehicle, a truck that wound up in a ditch, walked away from the incident with no physical injuries, Young said.

Those who were hurt in the crash were taken to the Clarenville hospital for treatment.
