Father-of-three Angelo Oliveros, 45, was driving northbound in the Massey tunnel last Friday afternoon when a black SUV suddenly swerved into his lane.
Oliveros, who was driving a packed 620 Bridgeport Station/Tsawwassen Ferry bus, found himself trapped in the tunnel, on a crash course with the SUV, with no place to go.
"He came along...Oh my God, then the next thing I know, I hit the brakes trying to avoid him and a head-on collision," Oliveros told the CBC.
"I closed my eyes and thought 'Oh my God, I am not going to make it'...I wasn't expecting to open my eyes again anymore."
Oliveros says he still doesn't know why the driver of the SUV suddenly swerved into his lane, but says his defensive driving training kicked in.
With counterflow traffic barring his escape in one direction, he swung his bus, carrying 35 passengers, hard into the tunnel wall, minimizing the impact of the head on collision.
Oliveros is now at home recovering and when he's ready, he says he needs to drive through that tunnel again.
"Maybe one of these days, I'll take the Tsawwassen ferry bus and then try to overcome this fear right now that I am kind of having."
The driver of the black SUV was taken to hospital with serious injuries. There were no reports of injuries to the bus passengers.
The collision closed the tunnel's northbound route and resulted in serious traffic delays at rush hour and the rerouting of a number of buses.
The cause of the collision is still under investigation.
