Passing a truck — Oklahoma Permit Test
Passing a truck on the Oklahoma permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When passing a truck, let the driver know you are passing by blinking your headlights, especially at night.
A driver who knows you are coming will keep to the far side of the lane and give you room.
Let the driver know you are passing by blinking your headlights, especially at night.
Because of their weight, trucks travel faster downhill and slower uphill, so you may have to increase your speed to pass a truck on a downhill grade.
A truck's weight pulls it down a hill quickly, so a pass that seems easy can take far longer than you planned.
Because of their weight, trucks travel faster downhill and slower uphill.
Complete your pass of a truck as quickly as possible and do not stay alongside it; after you pass, maintain your speed.
Slowing down in front of a truck going downhill forces the driver to brake hard with a heavy load behind.

If the truck driver blinks the truck's lights after you pass, it is a signal that you are cleared to pull back in front of the truck.
The truck driver sits high and can judge the gap behind you better than you can in your mirror.
If the driver blinks the truck’s lights after you pass, it’s a signal that you are cleared to pull back in front of the truck.
After passing a truck, move back in front only when you can see the front of the truck in your rearview mirror.

On the test
How can you let a truck driver know you are about to pass?
Blink your headlights. A driver who knows you are coming will keep to the far side of the lane and give you room. Oklahoma Driver Manual, p.54: “Let the driver know you are passing by blinking your headlights, especially at night.”
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.
