Snow and ice — Colorado Permit Test
Snow and ice on the Colorado permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A road covered with snow, snowpack or ice is most hazardous when the snow or ice begins to melt.
Melting water sits on top of the ice and takes the last of the grip away. The road looks better at exactly the moment it gets worse.
When the road is slippery, your tires do not grip as well and it will take longer to stop
Overpasses, bridges, shaded areas and snow packed portions of the road can be icy even when other pavement is not.
A bridge loses heat from underneath as well as on top, so it freezes first. Nothing about the road ahead of it warns you.

If you lose traction, take your foot off both the brake and the accelerator pedal and then turn the front wheels in the direction you want the car to go.
Braking or accelerating in a skid keeps the tires sliding. Off both pedals they can start rolling again, and rolling tires steer.

Everything you know about stopping distance was learned on dry pavement. Ice can double it or worse, with no warning at the wheel.

Drivers should be extra careful approaching or passing a snowplow or other snow removal equipment with flashing yellow lights that is clearing snow.
The plow is working at the edge of its lane and beyond it, and the road beside it has not been cleared yet.

It is illegal to pass a city, county or state-operated snow plow while it is working with its yellow lights flashing and driving in tandem with one or more other plows.
Plows in tandem are clearing the full width together. There is no lane between them, only the snow they are throwing.

On the test
When is a snow covered road most hazardous?
When the snow or ice starts to melt. Melting water sits on top of the ice and takes the last of the grip away. The road looks better at exactly the moment it gets worse. Colorado Driver Handbook, p.17: “When the road is slippery, your tires do not grip as well and it will take longer to stop”
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.
What it costs

- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
