A five-car crash on the Pat Bay Highway fortunately only resulted in minor injuries to those involved.

The chain-reaction collision happened on the highway near the entrance to Elk Lake and Beaver Lake Park Friday afternoon.

Three cars, a pickup truck and a semi-trailer truck were involved.

The crash, which caused rear-end damage to a number of vehicles involved, reduced traffic to one lane in both the northbound and southbound lanes of the highway.

Saanich police, fire and paramedics responded. Witnesses at the scene said drivers and occupants involved seemed to be out of their vehicles and walking around.

A significant amount of oil was spilled from the semi truck and firefighters placed absorbent materials on the road as a precaution.

Traffic in the area was moving slowly as a result.

Saanich police reminded drivers to slow down as they head into the weekend.

"We don't like reminders like this, but it is a good reminder for drivers that you've got to give yourself space between vehicles," said Sgt. Julie Fast. "Take your time, expect that it might take a little bit longer to get your destination."

The cause of the crash has not been confirmed.
