Passing and lane signs — Louisiana Permit Test

Passing and lane signs on the Louisiana permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

A PASS WITH CARE sign marks the end of a no passing zone; pass only when it is safe.

The road ahead is now open enough to see, but you still must check that the other lane is clear.

Pass with Care – This sign tells you that you are at the end of a no passing zone.

Class D & E Driver's Guide, p.28

Passing areas are based on how far you can see ahead.

Hills and curves hide oncoming cars. If you cannot see far, you cannot know the lane is clear.

Passing areas are based on how far you can see ahead.

Class D & E Driver's Guide, p.28

A KEEP RIGHT sign means traffic must stay to the right of a feature such as a median, island or lane divider.

Going left of the island would put you in the lane of cars coming toward you.

Keep Right – These signs indicate when traffic must stay to the right of a roadway feature or obstruction, such as an upcoming median, island or lane divider.

Class D & E Driver's Guide, p.28

A SLOWER TRAFFIC KEEP RIGHT sign tells slow drivers on a multilane highway to stay in the right lane.

Slow cars on the left make fast cars weave around them, and weaving causes crashes.

It tells the slow driver to stay in the right lane.

Class D & E Driver's Guide, p.29

On expressway ramps, a WRONG WAY sign stands a short distance past the DO NOT ENTER sign.

If you missed the first sign, the second one is your last warning before you meet fast traffic.

You will see this sign on expressway ramps a short distance past the “DO NOT ENTER” sign.

Class D & E Driver's Guide, p.29

DO NOT ENTER signs stand at openings you may not enter, such as exit ramps where you would go the wrong way, crossovers on divided roads and one-way streets.

These are the places where one wrong turn puts you nose to nose with traffic.

This sign is visible at roadway openings that you may not enter such as exit ramps where you would be going in the wrong direction, in crossovers on divided roadways and at numerous locations on one-way streets.

On the test

What does a PASS WITH CARE sign tell you?

The no passing zone has ended. The road ahead is now open enough to see, but you still must check that the other lane is clear. Class D & E Driver's Guide, p.28: “Pass with Care – This sign tells you that you are at the end of 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.
