Passing on the left — Oklahoma Permit Test
Passing on the left on the Oklahoma permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Before passing on the left, check ahead for at least 200 feet of clear roadway without a No Passing Zone.
You need room to get past and back in, and a pass started too short ends with you facing oncoming traffic.
Check ahead for at least 200 feet of clear roadway without a “No Passing Zone.”
As you get ready to pass, especially a large truck or bus, never get so close that the vehicle blocks your view of the road ahead; follow at a safe distance until you can see far enough ahead to pass.
Riding close behind a big vehicle hides the oncoming car you would be pulling out in front of.
As you get ready to pass, especially in a large truck or bus, never get so close that the vehicle blocks your view of the road ahead.
Before passing, be sure no other car is passing or about to pass your car at the same time; check your rearview mirror and look over your shoulder to check your blind spots.
If a car behind you is already pulling out to pass, moving left puts you directly into it.
Be sure that no other car is passing or is about to pass your car at the same time.
After passing, don't return to the right lane until you can see the car you passed in your rearview mirror.
Seeing the whole car in the mirror means you have left it room, so you will not cut it off as you move back.
Pass the car ahead and don’t return to the right lane until you can see that car in the rearview mirror.
On the test
Before passing on the left, how much clear roadway should you see ahead?
At least 200 feet. You need room to get past and back in, and a pass started too short ends with you facing oncoming traffic. Oklahoma Driver Manual, p.35: “Check ahead for at least 200 feet of clear roadway without a “No Passing Zone.””
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.
