Unposted speed limits — Alaska Permit Test
Unposted speed limits on the Alaska permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Where no other limit is posted, Alaska's speed limit in a business district is 20 mph.
Business streets are full of turning cars, parked cars and people stepping out, so a driver needs room to stop.
Business district, 20 mph.
Where no other limit is posted, Alaska's speed limit in an alley is 15 mph.
Alleys are narrow, with garages and fences hiding whoever steps out, so there is almost no room to react.
Alley, 15 mph.
Where no other limit is posted, Alaska's speed limit in a school zone is 20 mph.
Children dart into the street without looking, and a slower car can stop before it reaches them.
School zone, 20 mph.
Where no other limit is posted, Alaska's speed limit in a residential district is 25 mph.
Children, pets and parked cars crowd residential streets, so a driver needs time to stop for what steps out.
Residential district, 25 mph.
Where no other limit is posted, Alaska's speed limit on any other roadway is 55 mph.
Open roads still hide moose, ice and sharp bends, so the law sets a ceiling even where no sign is posted.
Any other roadway .......................... 55
On the test
What is the speed limit in an Alaska business district where no other limit is posted?

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.
