Const. Clint Sitbbe appeared on CBC radio's Metro Morning on Thursday and said police responded to 232 cars for collisions on Wednesday that caused either injuries or property damage.
"Every one of those was preventable, unfortunately driver error always attributes to the collisions," he said. "Everyone says it's an accident. But an accident is something that you can't prevent."
His point is that many commuters don't adjust their driving for the conditions.
"Yesterday had to be one of the worst days we've seen so far this year," he said.
Stibbe offered the following tips as drivers head back out on the roads this morning:
Don't follow too close: "When there's snow on the ground, a following distance of three to five seconds is not enough. Double it, or in some cases, even triple it. The faster you go, the longer it's going to take you to stop."
Clear snow and ice off your vehicle: "When people haven't taken snow off their vehicles, a lot of times they don't have a clear view of the outside. When they take a turn, they may hit a pedestrian."
Leave enough time for your trip: "A lot of people leave not enough time to get to their destination. As a result, they end up rushing and they get into collisions."
Keep the following in your trunk: Spare gas can. Extra food. A warm set of boots, gloves and a shovel. "I saw many incidents yesterday where people were stuck and couldn't do anything," said Stibbe. "They weren't prepared. They were stuck in their car, waiting for roads to clear or help to arrive."
The city says plow crews have been working through the night to clear city streets.
