Winter ice and snow — Wyoming Permit Test
Winter ice and snow on the Wyoming permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Watch for ice on bridges, overpasses and shaded areas, where it can remain even after the sun comes out.
A bridge has cold air above and below it and shade gets no sun, so ice stays there after the rest of the road is clear.
Watch for ice on bridges, overpasses and shaded areas, where it can remain, even after the sun comes out.
Black ice is invisible, so always watch for sudden changes in the road surface from merely wet to extremely icy.
A road that looks only wet can be a sheet of ice, and you will not know until the car starts to slide.
Black ice is invisible and is treacherous, so always watch for sudden changes in road surface conditions, from merely wet, to extremely icy.
Thawing temperatures can leave a thin film of water over melting ice, making it even more slick.
Water on top of ice acts like oil, so a warm afternoon can make a road worse, not better.
And thawing temperatures can also leave a thin film of water over melting ice, making it even more slick.
To start moving on snow and ice, accelerate slowly, steadily and carefully with the front wheels pointed straight ahead.
Too much power or turned wheels make the tires spin and slide instead of pulling the car forward.
Starting your car moving on snow and ice requires slow, steady and careful acceleration and front wheels that are pointed straight ahead.
Four-wheel-drive vehicles can still skid with sudden changes in power, and those with high centers of gravity are more likely to tip over in a skid.
Four-wheel drive helps you get going but not stop or steer, and a tall vehicle sliding sideways can roll.
And four-wheel-drive vehicles with high centers of gravity are also more likely to tip over in a skid.
On the test
Where can ice stay on the road even after the sun comes out?
On bridges and in shaded areas. A bridge has cold air above and below it and shade gets no sun, so ice stays there after the rest of the road is clear. Wyoming Rules of the Road Driver License Manual, p.44: “Watch for ice on bridges, overpasses and shaded areas, where it can remain, even after the sun comes out.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
