Interstate exiting — Louisiana Permit Test
Interstate exiting on the Louisiana permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
About a mile before your exit, check that you are in the correct lane to make the exit.
Getting into place early saves you from cutting across lanes at the last second.
Approximately a mile before your exit, check to make sure you are in the correct lane to make the exit.
When moving toward an interstate exit, change lanes one at a time.
Cutting across several lanes at once gives the drivers in each lane no time to see you coming.
Change lanes one at a time until you are in the proper lane to safely make the exit.
Signal your intention to exit for about 5 seconds.
A long signal gives drivers behind you time to notice that you will slow and leave the lane.
Signal your intention for approximately five seconds and make sure you are at the proper speed for leaving the traffic lane - not too fast so you won’t lose control and not too slow so the flow of traffic can still move freely.
If you miss your interstate exit, do not stop or back up; go on to the next exit and come back.
Backing up or stopping on an interstate puts a slow car in front of fast traffic and is against the law.
If you miss your exit, do not stop; do not back up!
Never slow down on the interstate itself to exit; wait until you are fully in the deceleration lane, then slow to the posted ramp speed.
Cars behind you expect you to keep pace until you have left their lane, so early braking invites a rear-end crash.
Wait until you are fully in the deceleration lane, and then reduce your speed to the posted ramp speed.
After you exit the interstate, be aware of two-way traffic ahead.
After miles of one-way lanes, drivers can forget that oncoming cars now share the road.
Be aware of two-way traffic ahead after your exit from the interstate.
On the test
When should you check that you are in the correct lane for your interstate exit?
About a mile before the exit. Getting into place early saves you from cutting across lanes at the last second. Class D & E Driver's Guide, p.102: “Approximately a mile before your exit, check to make sure you are in the correct lane to make the exit.”
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.
