BC Highway Patrol officers are investigating after a driver was spotted heading the wrong way along a stretch of Highway 99 through South Surrey last week.

Cpl. Melissa Jongema confirmed a report of the concerning behaviour was received on July 24.

"We conducted patrols and did not locate the driver at the time," Jongema told Peace Arch News.

Asked for further details, Jongema did not elaborate.

Dash-cam footage posted to Reddit shows a dark-coloured vehicle driving northbound in the southbound "fast" lane, as it approaches the 16 Avenue overpass.

"Definitely wasn't expecting to see this on my way home. I called the police," poster Saralentine writes.

Viewers responded with outrage, calling for the driver's licence to be immediately revoked; questioning how the motorist managed to make the mistake in the first place; and why they continued driving.

"It must have eventually become obvious they were going the wrong way," notes one.

Another notes such occurrences are happening "way too often" in the Lower Mainland.

"Sooo close to a fatal high speed collision," adds another.

There have been several fatal incidents on Lower Mainland roads in recent weeks. In one six-day stretch, 18 people were killed in seven separate crashes on B.C. highways.

One of those victims was a young woman who had only arrived in Canada as an international student two days prior to the July 11 crash that ended her life. The single-vehicle incident occurred in South Surrey, on Highway 99 just north of King George Boulevard.
