Police say they don’t expect to lay charges after a three-vehicle collision outside Fredericton sent four people to hospital Monday evening.

The collision happened around 5:30 p.m. on Route 102 in Island View, N.B.

Two vehicles ended up in a ditch while a third vehicle crashed into a guardrail on the opposite side of the road.

Fire crews confirmed there were seven people involved in the crash. Four people were taken to hospital with non-life-threatening injuries.

RCMP Cpl. Jean-Francois Martel told the KHJ newsroom it appears one of the drivers may have fallen asleep behind the wheel.

Martel said there's no indication that speed or alcohol were factors, but added the crash is still under investigation.

The collision also downed a power pole and put the busy route down to one lane of traffic.
