Turning maneuvers — Iowa Permit Test
Turning maneuvers on the Iowa permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Do not cut corners and do not swing wide on your turns; both raise your chance of a crash.
Cutting a corner puts you in the other lane, and swinging wide invites a car to slip in beside you.
Do not cut corners, and do not swing wide on your turns.
Three-point turns are generally not safe; it is better to go on to the nearest intersection.
Turning around in the middle of the road blocks traffic both ways and leaves you exposed to a crash.
It is better to proceed to the nearest intersection.
Make a U-turn only where it is not prohibited and where it is safe to do so.
A U-turn crosses every lane of traffic, so it is only safe where you can see far both ways.
U-Turns should only be performed where their use is not prohibited and where it is safe to do so.
On the test
What should you avoid when making a turn?
Cutting the corner or swinging wide. Cutting a corner puts you in the other lane, and swinging wide invites a car to slip in beside you. Iowa Driver's License Manual, p.43: “Do not cut corners, and do not swing wide on your turns.”
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.
