“There was a black car right in front of the bus,” Tanti said over Facebook. “[I’m] sure he got a fright seeing that come out in front of him.

“The roads were fine,” he added. “Not a lot of standing water.”

Medix BC posted to Facebook asking the public to “avoid the area at all costs” while emergency crews secured the scene.

According to DriveBC, the crash impacted traffic in both directions.

DriveBC also had a weather condition alert for the Malahat, noting heavy rain and water pooling between Highway 14 and Whittaker Road.
