Distractions before driving — Colorado Permit Test
Distractions before driving on the Colorado permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Distractions are the leading cause of driver error, and a distraction is anything that takes your attention from driving even momentarily.
A moment is all it takes at 30 mph to cover the length of a house. The car keeps going while your attention is somewhere else.
Distractions are the leading cause of driver error
Before beginning a trip you should adjust your seat, mirrors, radio and temperature and secure any loose objects in the car.
Every one of those is a job that will otherwise get done while you are moving. Doing them parked costs a minute and no attention at all.

A driver who needs to deal with a distracting or urgent situation should safely pull over to address it.
Whatever it is will still be there in a parking space. Trying to handle it while driving is how a small problem becomes a crash.
Safely pull over to address distracting or urgent situations
Before driving, make sure everyone in the vehicle, particularly children, is wearing an age-appropriate restraint device.
A child who unbuckles halfway through a trip will pull you round to look. Checking first keeps your eyes where they belong.

On the test
What does the handbook call the leading cause of driver error?
Distractions. A moment is all it takes at 30 mph to cover the length of a house. The car keeps going while your attention is somewhere else. Colorado Driver Handbook, p.6: “Distractions are the leading cause of driver error”
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.
