Highway 101 has reopened following a multi-vehicle crash this morning that killed a 23-year-old Hants County man.

The inbound section between Exit 3 and Exit 4 was closed following the 8 a.m. crash as RCMP investigated the cause.

RCMP say the man who died was driving a Saturn, which was pinned between a cube van and a Nova Scotia Power truck towing a Volkswagen. The Volkswagen then hit a Hyundai Accent.

RCMP Const. Andrew Standen said four people were treated for minor injuries and released after the crash. They were in the cube van, Nova Scotia Power truck and Accent.

"There were flames on the bottom of the [Nova Scotia] Power truck that were extinguished using hand held fire extinguishers, prior to fire arriving and then they took over that side of it," he said.

Standen said people need to use caution driving in winter conditions.

"It's a reminder to people that even if you've got an all-wheel drive or four-wheel drive and great snow tires, take your time getting where you're going. If you've got a good, clear portion of highway, just stay on that and avoid passing because it's just not worth it for the extra 10 minutes you're going to [save]," he said.

The CBC's Stephanie van Kampen said it looked like the Nova Scotia Power truck struck a car from behind, which crushed the car between that vehicle and another large truck. 

Nova Scotia Power confirmed one of their trucks was involved in the crash.

"The truck was being driven from the Annapolis Valley to our Lakeside depot by the employee of a professional driving firm that Nova Scotia Power contracts to move our vehicles between locations. The RCMP is investigating the cause of the collision," the utility said in a news release.

"The thoughts and prayers of Nova Scotia Power management and employees are with those involved in the collision and their families."
