Police are reminding both drivers and pedestrians to pay more attention on the road after two young children and their mother were hit by a car as they crossed a street in Surrey.

A four-year-old girl and her six-year-old brother were crossing the road with their mom and dad around 6 p.m. Tuesday at 76th Avenue at 147A Street when three of them were struck.

The little girl suffered critical injuries and is in serious condition, and her brother was also seriously hurt. The mother suffered minor injuries.

Police say there were several other people in the same crosswalk at the time.

Cpl. Brian Fedirchuk of Surrey RCMP Traffic Services is urging caution.

“Pedestrians…really need to pay attention. Drivers, you need to pay attention as well,” he said.

“Don't assume that pedestrian is waiting for you to go. That pedestrian may not have seen you just as easily as you may not have seen them.”

The driver stayed on scene and called 911. Police say that person is cooperating with the investigation, and drugs, alcohol and speed are not being considered as factors.

The City of Surrey says the crosswalk was installed in mid-January.
