Speed limit table — Mississippi Permit Test
Speed limit table on the Mississippi permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Mississippi's speed limit table is for passenger automobiles, including 1/2-ton trucks that are unloaded.
Heavier and loaded trucks need more room to stop, so the car limits are not written for them.
SPEED LIMITS FOR PASSENGER AUTOMOBILES (including 1/2-ton trucks, unloaded)
The maximum speed for a passenger car on a Mississippi interstate is 70 mph.
Going over the top limit on a fast road leaves no margin when traffic slows ahead.
Interstates 70 mph 40 mph
The minimum speed for a passenger car on a Mississippi interstate is 40 mph.
A car crawling on the interstate gets rear-ended by traffic that comes up on it fast.
Interstates 70 mph 40 mph
The maximum speed for a passenger car on a four-lane state or U.S. highway in Mississippi is 65 mph.
Four-lane highways have side roads and driveways that interstates lack, so their top speed is lower.
Four-lane Highways (State & U.S.) 65 mph 40 mph
The minimum speed for a passenger car on a four-lane state or U.S. highway in Mississippi is 40 mph.
A very slow car on a fast highway forces others to brake hard or pass in a hurry.
Four-lane Highways (State & U.S.) 65 mph 40 mph
The maximum speed for a passenger car on a two-lane state or U.S. highway in Mississippi is 55 mph.
On a two-lane road the oncoming cars are only a few feet away, so the top speed is lower.
Two-lane Highways (State & U.S.) 55 mph
The maximum speed for a passenger car on the Natchez Trace Parkway is 50 mph.
The Parkway is a slow, scenic road, and driving it like a highway puts you over its limit.
Natchez Trace Parkway 50 mph
On the test
Which vehicles does the manual's speed limit table cover?
Cars and unloaded 1/2-ton trucks. Heavier and loaded trucks need more room to stop, so the car limits are not written for them. Mississippi Driver's License Manual, p.41: “SPEED LIMITS FOR PASSENGER AUTOMOBILES (including 1/2-ton trucks, unloaded)”
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.
What it costs

- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.

- Do the work, fail the real exam, and we refund you.
