What does it indicate if your tires stop throwing spray and the road noise suddenly goes quiet on a wet, near-freezing road?
- A.The road has definitely dried
- B.The surface may have turned to ice, so you should slow gently and test traction with great care
- C.You may safely speed up
- D.Your tires have gained extra grip
Correct answer
B. The surface may have turned to ice, so you should slow gently and test traction with great care
Why
A wet road throws spray and makes noise; an icy one often looks similar but behaves silently and slick. Experienced winter drivers treat that sudden quiet, plus ice on mirrors or antenna, as an early ice warning before the truck itself begins to slide.
