Winter safety tips

The “penny test” is a quick rule-of-thumb measure to check the amount of tread on a vehicle tire. To properly perform this test, place a penny upside-down in the tire tread and measure how far the tire overlaps the coin. If the tread is below the hair of Abraham Lincoln’s head, your tire is considered ‘unsafe’ for winter driving. (U.S. Air Force graphic by Senior Airman John A. Crawford)
