Gullicksonm, who has back injuries and a shattered leg, told CBC News he was driving home with his girlfriend and his sister in the car when he noticed someone at the side of the road.

"Everyone's passing her, you know. Dark out, late at night... everyone's passing her, not caring. So I went out of my way, did a U-ey, after I asked everyone in the car if I should. We agreed, so I pulled over, gave her a jump."

Gullickson said the driver managed to travel only a block or so before she needed another jumpstart.

"As I was jumping her the second time, I heard 'Watch out.' Looked up, seeing headlights, hit my car, my car rammed into her car, I rolled under my car, legs above my head."

Gullickson's girlfriend, Cassy Dryden, was also seriously injured in the incident with a broken neck.

RCMP Cpl. Bert Paquette says it's too soon to say if speed or alcohol were factors, or if charges will be laid.

"The Good Samaritan, as far as we know, suffered significant injuries and is in critical but stable condition in hospital at this time," he said.

Although he worries about having to pay the bills while not being able to work, Gullickson said he doesn't regret being a Good Samaritan.

"I'm glad that I helped her. I don't have any regrets helping her," he said.

Friends have set up an account at the Bank of Montreal to help pay for the couple's expenses.

Photos of the couple in hospital were posted to a Facebook page called the "Cassy Dryden and Brandon Gullickson Fund" on Tuesday.
