Snow and ice driving — Wyoming Permit Test
Snow and ice driving on the Wyoming permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Equip your car with snow tires or chains to prevent skidding and to reduce stopping distance.
Ordinary tires slide on packed snow, so the car needs more road to stop.
your car with snow tires or chains to prevent
On snow or ice, do not change speed or direction suddenly; slow gradually and smoothly before stopping or turning.
A sudden move breaks the little grip the tires have and starts a skid.
NOT change speed or direction suddenly.
Never lock your brakes on snow or ice: you have no steering control unless the wheels are turning.
Locked wheels slide like a sled, and turning the wheel does nothing.
Never lock your brakes. You have no steering control unless the wheels are turning.
Do not use cruise control on snow or ice.
Cruise control can spin the wheels on a slick patch before you notice and react.
DO NOT use cruise control.
On the test
What does the manual recommend fitting to your car for snow?
Snow tires or chains. Ordinary tires slide on packed snow, so the car needs more road to stop. Wyoming Rules of the Road Driver License Manual, p.79: “your car with snow tires or chains to prevent”
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.
