Exiting the interstate — Mississippi Permit Test
Exiting the interstate on the Mississippi permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
To exit the interstate, be in the correct lane at least one-quarter mile before your exit.
Cutting across lanes at the last second to make an exit causes crashes.
To exit the interstate, be sure you are in the correct lane at least one-quarter mile from your exit.
Most exits are on the right, but some are on the left and require you to exit from the left-hand lane; watch the signs.
A driver who expects every exit on the right may be in the wrong lane when it comes.
Most exits are on the right and require you to exit from the right-hand lane. However, some exits are on the left and require you to exit from the left-hand lane.
Do not slow down until you have safely moved into the deceleration lane; then slow to the posted limit and turn off your signal.
Braking in a travel lane surprises the fast traffic behind you.
Do not slow down until you have safely moved into the deceleration lane.
If you miss your exit, do not stop and back up; continue to the next exit. Never stop, back up, or turn around on an exit ramp.
A car backing on the interstate or a ramp meets traffic that never expects it.
If you miss your exit, do not stop and back up. Continue to the next exit.
On the test
How far ahead of your exit should you be in the correct lane?
At least one-quarter mile. Cutting across lanes at the last second to make an exit causes crashes. Mississippi Driver's License Manual, p.69: “To exit the interstate, be sure you are in the correct lane at least one-quarter mile from your 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.
