Use of lanes — Kentucky Permit Test
Use of lanes on the Kentucky permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Where a Kentucky road has three or more lanes in one direction, the middle lane or lanes are for through traffic.
Sorting by what each driver is doing is what keeps a wide road moving at all.
If there are three or more lanes in one direction, the middle lane or lanes are for through traffic.
The left lane on a Kentucky multi-lane road is for drivers who want to pass or turn left.
Sitting in the left lane at the speed of the traffic is what backs a highway up behind one car.
The left lane is for drivers who want to pass or turn left.
The right lane on a Kentucky road is used by drivers who want to go slower or who are entering or turning right.
Slower traffic on the right leaves the rest of the road free to flow around it.
The right lane is used by drivers who want to go slower or who are entering or turning right.
Remaining in the left lane on a Kentucky limited access highway is illegal.
It is not merely bad manners. The state says it is against the law.
Remaining in the left lane on a limited access highway is illegal.
On a Kentucky road with only two lanes in one direction, the right lane generally has the smoothest traffic flow and the left is reserved for passing.
Two lanes work the same way as three, with the middle lane missing.
If a road has only two lanes in one direction, the right lane generally has the smoothest traffic flow, with the left lane being reserved for the passing of other vehicles.
A Kentucky driver turning into another street turns into the lane nearest to them.
Cutting across into the far lane is how two turning cars from opposite directions collide.
While turning into another street, turn into the lane nearest to you.
A Kentucky driver turning left from a street with two or more lanes turns from the lane nearest the center lane, and one turning right turns from the lane nearest the curb.
The lane a driver turns from is decided before the intersection, not in it.
If you are turning left from a street with two or more lanes, turn from the lane nearest the center lane.
A Kentucky driver who needs to change to another lane after a turn does so only after the turn is finished and the traffic is clear.
Finishing one maneuver before starting another is what keeps them both visible to everyone else.
If you need to change to another lane, do so only after you have finished your turn and when the traffic is clear.
A Kentucky driver who misses a turn goes on to the next intersection and works their way back.
Braking hard or swinging across for a missed turn is how the car behind ends up in the trunk.
If you miss your turn, go on to the next intersection and work your way back to where you want to go.
On the test
What are the middle lanes for on a Kentucky road with three or more lanes?
Through traffic. Sorting by what each driver is doing is what keeps a wide road moving at all. Kentucky Driver Manual, p.46: “If there are three or more lanes in one direction, the middle lane or lanes are for through traffic.”
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.
