Turning — Colorado Permit Test
Turning on the Colorado permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When turning right you should turn from the right most part of your lane and as close to the curb as possible.
Hugging the curb leaves no gap for a bicycle or a car to slip up your inside. A wide right turn is where they get caught.
When turning right you should turn from the right most part of your lane and as close to the curb as possible.
When turning left you should be in the left side of your lane.
Starting from the left of your lane gives you the shortest path across the oncoming lanes, so you are exposed for less time.

To make a right turn you must begin in the right most lane.
Turning right from anywhere else cuts across a lane somebody is going straight in. It is the classic collision at a wide corner.

Complete your turn in the center of the correct lane on the new roadway, usually the lane closest to you on your side of the street.
Finishing in the wrong lane puts you beside somebody who was already there. The nearest lane is the one nobody else is turning into.

Avoid short turns that cut the corner, wide turns, late turns and straddling lanes.
Each of those four puts part of your car where another driver had every reason to expect empty road. They are the four ways a turn goes wrong.

Accelerate out of turns until you reach the speed limit or the flow of traffic.
Leaving a turn slowly holds up everybody behind and leaves you exposed in the intersection for longer than you need to be.

On the test
Where in the lane should a right turn start?
From the right most part, close to the curb. Hugging the curb leaves no gap for a bicycle or a car to slip up your inside. A wide right turn is where they get caught. Colorado Driver Handbook, p.12: “When turning right you should turn from the right most part of your lane and as close to the curb as possible.”
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.
