The Denver Police Department reported a spike in traffic collisions and vehicle theft resulting from Monday’s winter weather.

Between midnight and 8 a.m., there were 12 crash reports in Denver, police said.

In the same time frame, there were also four stolen vehicles resulting from owners leaving running cars unattended to heat up.

“Keep up that safe driving, and remember an unattended running vehicle is like an invitation to car thieves,” police said in a tweet.

The Colorado Department of Transportation offers tips for winter driving:

  • Do not travel in the snow unless your vehicle is ready for the weather
  • Make sure you have appropriate tires with good tread for the weather
  • Carry an emergency kit in your car, including extra water, food and blankets
  • When driving on slick roads, take it slow and leave ample room behind the vehicle ahead
  • Give yourself extra time to reach your destination
