  • Safety is improved by a temporary increase in skid friction resistance and a reduction in the potential for hydroplaning.
  • Bald tires significantly reduce your traction on wet roadways, and offer little resistance to hydroplaning.
  • If the vehicle is hydroplaning, do not use the brakes to slow down.
  • Spring covers heavy rains, and hydroplaning as well as high winds.
  • If ponding on the traveled way occurs, hydroplaning becomes an important safety concern.
