Traffic was impacted on the Malahat Highway after a commercial truck struck a centre median.
Vehicles are still moving in both directions but there are delays expected after traffic was briefly closed southbound.
There was no immediate update on the driver’s condition.
The crash occurs just days after the Malahat was fully reopened to two-way traffic following damaging floods on the highway.
Repair work is continuing on the Malahat at Tunnel Hill after it was badly damaged by last week’s torrential rain.
