Passing safety — Louisiana Permit Test
Passing safety on the Louisiana permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
On multi-lane roads, the left-most lane is meant for passing slower vehicles.
Keeping the left lane for passing lets faster cars get by without weaving around you on the right.
On multi-lane roads, the left-most lane is intended to be used for passing slower vehicles.
Do not pull up close behind a vehicle you plan to pass, especially a truck or bus, because it blocks your view.
Tucked in close behind a big vehicle, you cannot see the road ahead or a car coming toward you.
Do not pull up closely behind the vehicle you intend to pass (especially a large truck or bus).
If you can see an oncoming vehicle, do not try to pass.
It is very hard to judge how fast a car coming at you is moving. It is closer than it looks.
If you can see an oncoming vehicle, do not attempt to pass.
An oncoming vehicle more than 25 seconds away generally appears to be standing still.
A car far off down the road looks parked even when it is moving fast, so it fools you into thinking you have time.
An oncoming vehicle that is more than 25 seconds from your vehicle generally appears to be standing still.
It is safe practice to tap the horn lightly when passing so you do not surprise the driver being passed.
A driver who does not know you are there may drift into your lane. A light tap tells them you are coming by.
It is safe practice to tap the horn lightly to avoid surprising the overtaken driver.
Before moving back into your lane after passing, wait until you can see the passed car in your rearview mirror.
If you cut back in too soon, you clip the front of the car you just passed or make it brake hard.
An accepted rule is to wait until you see the other car in your rear view mirror.
When you are being passed, slow down a little and, on a two-lane highway, move over to the right as far as you safely can.
Giving the passing driver room and time lets them get back in lane sooner, away from oncoming cars.
Slow your speed a little and, if on a two-lane highway, mover over to the right as far as you can safely.
Start a pass from at least 2 seconds behind the vehicle you are passing.
Starting from too close means you swing out right next to its rear corner and may hit it.
Pass from at least two seconds (behind the vehicle to be passed) to avoid striking the rear side of the vehicle.
Pass as quickly and safely as you can; the longer you ride alongside, the longer the other vehicle might move into your lane.
Every second side by side is a second the other driver could drift over without seeing you.
The longer your vehicle stays alongside the other vehicle, the longer you are in danger of the other vehicle moving toward your lane.
On the test
On a road with several lanes each way, which lane is meant for passing slower vehicles?
The left-most lane. Keeping the left lane for passing lets faster cars get by without weaving around you on the right. Class D & E Driver's Guide, p.72: “On multi-lane roads, the left-most lane is intended to be used for passing slower vehicles.”
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.
