Turns — Missouri Permit Test
Turns on the Missouri permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Where no signs or lane markings control turning, turn from the lane closest to the direction you want to go and turn into the lane closest to the one you came from.
Taking the nearest lane on each side crosses the fewest paths. Every extra lane you cross is another car that has to guess.
you should turn from the lane that is closest to the direction you want to go, and turn into the lane closest to the one you came from
Before you make any turn you should look both ways for oncoming traffic or pedestrians.
A turn moves you across somebody else's path. Looking both ways is how you find out whose.
Before you make any turn, you should look both ways for oncoming traffic or pedestrians.
When making turns, move from one lane to the other as smoothly as possible without crossing lane lines or interfering with traffic.
Cutting across lines mid-turn puts you somewhere no other driver expected. Smooth is also predictable.
When making turns, go from one lane to the other as smoothly as possible without crossing lane lines or interfering with traffic.
On right turns, avoid swinging wide to the left before turning.
A swing left reads as a lane change to the driver behind you, and they may try to pass on your right just as you turn into them.
If you swing wide, the driver behind you may think you are changing lanes or going to turn left, and may try to pass you on the right.
When making a left turn, avoid cutting the corner so sharply that you run into someone approaching from the left.
The corner you cut is the lane somebody else is arriving in. It is the one place a left turn meets traffic head on.
When making a left turn, avoid cutting the corner so sharply that you run into someone approaching from the left.
When turning left you must leave room for oncoming vehicles to turn left in front of you.
Two cars turning left across each other need to pass somewhere. Crowding the middle leaves them nowhere.

Turning from a one-way street onto a two-way street, begin the turn in the left lane and enter the two-way road to the right of its yellow dividing line.
The yellow line is the boundary of oncoming traffic. Entering to the right of it is the whole of the rule.
to the right of its yellow dividing line. If the two-way road is a four-lane road, you may enter it in the right lane if that lane is free of traffic.
Turning from a two-way street onto a one-way street, begin the turn with your left wheel as close as possible to the yellow dividing line.
Starting close to the line keeps the turn tight and keeps you out of the lane beside you.
Begin the turn with your left wheel as close as possible to the yellow dividing line.
Turning from a two-way street onto a two-way street, enter the road to the right of its center line.
Every left turn ends on the right-hand side of the road you join. The center line is what tells you which side that is.
Enter the road to the right of its center line.
On the test
With no markings to control turning, which lane should you turn into?
The lane closest to the one you came from. Taking the nearest lane on each side crosses the fewest paths. Every extra lane you cross is another car that has to guess. Missouri Driver Guide, p.24: “you should turn from the lane that is closest to the direction you want to go, and turn into the lane closest to the one you came from”
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.
