Vehicle emergencies — Colorado Permit Test
Vehicle emergencies on the Colorado permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If the brakes fail, take your foot off the accelerator and pump the brake pedal several times, which will often build up enough brake pressure to let you stop.
Most brake failures are a loss of pressure rather than a loss of the brakes. Pumping can put enough back to stop the car once.
Take your foot off the accelerator. Pump the brake pedal several times
If pumping the brakes does not work, use the parking brake slowly so you do not lock the rear wheels and cause a skid, and be ready to release it if the vehicle starts to skid.
Pulled hard, the parking brake locks the back wheels and spins the car. Pulled slowly, it is a brake you can still steer with.
Pull on the parking brake handle or push on the parking brake pedal slowly so you will not lock the rear wheels and cause a skid.
If the brakes cannot be restored, shift to lower gears, look for a safe place to slow to a stop, make sure the car is off the roadway, and do not drive the vehicle without brakes.
A lower gear takes speed off without the brakes at all. Getting off the road matters because the car will roll again the moment it stops.
Don’t drive the vehicle without brakes
If a tire blows out, hold the steering wheel tightly, keep the vehicle going straight as you slow down gradually, take your foot off the gas pedal and use the brakes lightly.
Braking hard on a blown tire pulls the car sideways. Holding it straight and letting it slow is what keeps it on the road.

After a tire blowout, do not stop on the road if possible, and once you have slowed pull off the road in a safe place.
A car stopped in a live lane is a hazard to everybody behind. Getting off the road is worth the extra few hundred feet on a flat tire.
Do not stop on the road if possible
If the power fails, keep a strong grip on the steering wheel, pull off the roadway, and expect the steering to be difficult and the brake pedal to need a very hard push.
The steering and the brakes still work without power assistance, but they take far more effort. Drivers who expect nothing happens give up too early.
The brakes will still work but you may have to push very hard on the brake pedal
If the headlights fail, pull off the road as soon as possible and try the headlight switch a few times, and if that does not work put on the emergency flashers, turn signals or fog lights.
Being seen is the immediate problem, not seeing. Any light at all is better than a dark car on a dark road.
If that does not work, put on the emergency flashers, turn signals or fog lights, if you have them
If the gas pedal jams, keep your eyes on the road, quickly shift to neutral, pull off the road when it is safe to do so, and turn off the engine.
Neutral disconnects the engine from the wheels at once, which is faster and safer than switching off while moving.
Quickly shift to neutral
Following the recommended vehicle maintenance schedule in the owner’s manual greatly reduces the chance that a vehicle will have a problem.
Almost every emergency in this section is a part that was already failing. Servicing finds them while the car is parked.

On the test
What should you do first if the brakes fail?
Take your foot off the gas and pump the brake. Most brake failures are a loss of pressure rather than a loss of the brakes. Pumping can put enough back to stop the car once. Colorado Driver Handbook, p.26: “Take your foot off the accelerator. Pump the brake pedal several times”
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.
