I-75 runs about 1,786 miles from Hialeah, Florida to Sault Ste. Marie, Michigan — the full length of the eastern United States, through six states. It is one of the busiest snowbird and freight corridors in the country, and the rest area rules on it are inconsistent enough to plan around.
The state you need to know about
Tennessee does not allow overnight truck parking at its rest areas. Drivers report a two-hour limit, statewide and enforced, with officers able to check logs and issue citations. I-75 crosses Tennessee through Chattanooga and Knoxville — squarely in the middle of the route, and exactly where a long-haul driver would want to break.
Plan your Tennessee stop as a short break and your overnight elsewhere.
State by state, south to north
Florida — overnight parking is allowed at many rest areas. Florida operates well-maintained facilities and welcome centers along I-75, including on the Alligator Alley and Naples–Tampa stretches.
Georgia — state law expressly protects the "normal, customary, and temporary use of safety rest areas, welcome centers, tourist centers" for resting, sleeping and eating. No defined time limit, but camping remains prohibited. Facility locations and hours are published by Georgia DOT.
Tennessee — no overnight at rest areas. Two hours reported and enforced.
Kentucky — overnight parking generally permitted; posted signs govern.
Ohio — no overnight camping at rest areas, with one significant exception: eight service plazas on the Ohio Turnpike accept RVs up to 40 feet for overnight stays. If you need an Ohio overnight, the Turnpike plazas are the answer rather than the I-75 rest areas.
Michigan — overnight parking generally permitted at rest areas.
Posted signs at the facility override every guide, including this one. State DOT sites are the authority.
The Georgia–Tennessee whiplash
This is the corridor's defining quirk. Georgia has no time limit at all and explicitly protects sleeping at rest areas in statute. Cross into Tennessee and you have two hours.
Northbound, that means: if you are tired approaching Chattanooga, stop in Georgia before the line rather than pushing into Tennessee. Southbound, it means Georgia is the first place you can properly rest after Tennessee.
Two hundred miles of planning difference, decided by a state line.
The rules that never change
Camping is prohibited at every rest area in every state. Sleeping inside your vehicle is permitted where the state allows it; slide-outs, awnings, chairs and outdoor gear are not.
Truck spaces are for commercial trucks. I-75 carries heavy freight and, in season, heavy snowbird RV traffic simultaneously. When RVs take truck spaces, drivers with mandatory rest requirements park on shoulders instead.
The snowbird factor
I-75 is the primary north–south migration route between the Midwest and Florida. In late autumn southbound and early spring northbound, rest area lots on this corridor fill early and stay full.
Practical consequence: in migration season, plan your stop earlier in the evening than you otherwise would. A facility that has space at 8 p.m. will not at midnight.
Why stopping matters
Drowsy driving causes roughly 100,000 crashes a year, concentrated between midnight and 6 a.m. Snowbird driving in particular tends toward long single-push journeys by older drivers, which is a fatigue profile worth taking seriously.
The Florida-to-Michigan run is not a one-day drive. Treating it as one is how the statistics happen.
Rest area versus truck stop
Rest areas — state DOT facilities under state administrative code. Free, time-limited, no camping.
Truck stops — private businesses, own rules. The correct choice in Tennessee, and in Ohio outside the Turnpike plazas.
On I-75 you will use both. Knowing which states require which is the planning work.
Weather
The corridor spans subtropical Florida to the Upper Peninsula, so the hazards change completely along its length.
Southern Florida: heat, and summer afternoon thunderstorms. The Appalachian sections in Tennessee and Kentucky: winter ice on grades. Michigan and northern Ohio: lake-effect snow, which can arrive fast and reduce visibility to nothing.
A rest area is the right place to wait out lake-effect snow. Check whether the state you are in permits the length of stay you may need.
Before you leave
On I-75 the two failure modes are a full lot in migration season and a state line you did not plan for.
BoardSpy shows the rest stops, fuel and food actually along your route as you drive it, with live weather on the road ahead rather than where you are now — so a snow band or a storm cell shows up before you reach it.

Frequently asked questions
Can you sleep at Georgia rest areas on I-75?
Yes, for resting, sleeping and eating. Georgia law sets no defined time limit. Camping is still prohibited.
What is the Tennessee rest-area rule on I-75?
No overnight at rest areas. About two hours, reported and enforced, through Chattanooga and Knoxville. Plan Tennessee as a short break.
Can RVs overnight at Ohio rest areas on I-75?
Not at ordinary I-75 rest areas. Eight Ohio Turnpike service plazas accept RVs up to 40 feet overnight. That is the Ohio exception.
Do I-75 rest areas fill up in snowbird season?
Yes. Late autumn southbound and early spring northbound, lots fill early. Plan to stop earlier in the evening than you would off-season.
Should you stop in Georgia or Tennessee if you are tired near Chattanooga?
Northbound, stop in Georgia before the line. Southbound, Georgia is the first place you can properly rest after Tennessee.
