Changing lanes blind spots — Oklahoma Permit Test
Changing lanes blind spots on the Oklahoma permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Never change lanes until you are sure it is safe; check your mirrors, signal, and look over your shoulder in the direction you will be moving.
Mirrors leave blind spots beside your car, and a quick look over your shoulder is what finds the car hiding there.
Never change lanes until you are sure it’s safe.
Before changing lanes, signal your intention to change lanes.
A signal gives the drivers around you a second or two to see your move coming and make room.
Signal your intention to change lanes.
When changing lanes, stay clear of the blind spots of the vehicle ahead of you.
If the driver ahead cannot see you, they may move into your lane as if it were empty.
Stay clear of the blind spots of the vehicle ahead of you.
When a driver ahead of you signals a lane change, slow down and leave space for the change.
Making room lets the other driver move over smoothly instead of squeezing in front of you and braking.
When a driver ahead of you signals a lane change, slow down and leave space for the change.
On the test
Before changing lanes, which way should you look over your shoulder?
In the direction you will be moving. Mirrors leave blind spots beside your car, and a quick look over your shoulder is what finds the car hiding there. Oklahoma Driver Manual, p.33: “Never change lanes until you are sure it’s safe.”
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.
