Parking rules — Colorado Permit Test
Parking rules on the Colorado permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Leave the vehicle in park if it has an automatic transmission, set the emergency brake, and remove the ignition key when leaving the vehicle.
Three things hold a parked car still and any one of them can fail. The key matters because a car left running is a car somebody can take.
Set the emergency brake and remember to remove the ignition key when leaving the vehicle
With a standard transmission, leave the vehicle in low gear when headed uphill and in reverse gear when headed downhill.
The gear is a brake of last resort, and it has to hold against the way the car would roll. Which gear depends on which way the hill runs.
If it’s a standard transmission, leave the vehicle in low gear when headed uphill and in reverse gear when headed downhill
You may not park on a crosswalk, sidewalk, bridge, elevated structure, railroad tracks or any controlled access highway.
Each one is a place where a parked car forces somebody else into danger, whether that is a walker into the road or a driver into a live lane.
On a crosswalk, sidewalk, bridge, elevated structure, railroad tracks or any controlled access highway ● Within 30 feet of a traffic signal, stop sign, railroad crossing or within 15 feet of a fire hydrant ● Within an intersection, tunnel, runaway truck ramp, on/ off ramp or blocking a driveway ● In a bike lane Parallel parking:
You may not park within 30 feet of a traffic signal, stop sign or railroad crossing.
A car parked that close hides the sign or the signal from everybody approaching. Thirty feet is what keeps the view open.
Within 30 feet of a traffic signal, stop sign, railroad crossing or within 15 feet of a fire hydrant ● Within an intersection, tunnel, runaway truck ramp, on/ off ramp or blocking a driveway ● In a bike lane Parallel parking:
You may not park within 15 feet of a fire hydrant.
A fire crew has to get a hose onto the hydrant in seconds. A car on top of it costs them the time a building does not have.

You may not park within an intersection, tunnel, runaway truck ramp, on-ramp or off-ramp, or block a driveway, and you may not park in a bike lane.
Every one of those is a place traffic has to keep moving through. A runaway truck ramp is the extreme case: it exists for a truck with no brakes.

Where parallel parking is permitted your vehicle must be within 12 inches of the curb, or as close as possible to the outside edge of the shoulder, so traffic is not blocked or slowed.
A foot is about the width of a hand span twice over. Further out and your car is sticking into the lane people are driving in.

To pull away from a parallel parked position, signal, check your mirrors and blind spots, and pull away when it is safe.
You are joining moving traffic from a standstill, which is the hardest merge there is. The blind spot check is the one drivers skip.
To pull away from a parallel parked position, activate your signal, check your mirrors and blind spots, and pull away when safe
On the test
What should be done every time you leave a parked vehicle?
Set the emergency brake and remove the key. Three things hold a parked car still and any one of them can fail. The key matters because a car left running is a car somebody can take. Colorado Driver Handbook, p.13: “Set the emergency brake and remember to remove the ignition key when leaving the vehicle”
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
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- 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.
