You’re probably prepared for winter, but what about your car?

The leaves are falling, the temperatures are dropping, and it’s a good time to get your car ready for winter. At least before it gets really cold.

“You need to check tire tread depth,” said John Giannini, the mechanical service director for Smith Honda and Smith Chevrolet. “You want enough tread to get around on the snow and ice.”

A simple way to check your tread depth is to place a quarter upside-down in between your tire ridges. If you can see the entire head of George Washington, you probably should consider getting new tires for winter driving.

Other things to check for winter driving include washer fluid levels, the windshield wipers, and your radiator fluid levels. Giannini also says it’s good to get your battery tested the next time your car’s in for maintenance.

“It’s always nice to have a safe vehicle whether its in the summer or the winter,” said Giannini. “But in the winter there’s a chance for it to get really cold. Having to walk somewhere in the winter is definitely more crucial than when it’s summer.”

Safety advocates also say having emergency essentials in your vehicle like water, snacks, a blanket, and some source of light are important.
