Texas is the size of France and Spain together, and it drives like it: long, fast, straight roads where the destination is measured in hours rather than miles. The rules are ordinary; the scale is not. This page is about the scale, the fast freeways, and the handful of things the state actually requires.
The rules, with their sources
Each rule below links to the official text we read and the date we read it. Rules change: if a date is old, check the source.
Speed limits: up to 85 mph on one toll road
Texas posts 75 mph on rural interstates and permits 80 or 85 mph on specified segments. The 85 mph stretch is State Highway 130, the toll bypass east of Austin — it is a real road with a real limit, and the toll is the price of using it.

Moving to Texas changes your paperwork, not your holiday
New residents must obtain a Texas driver licence from the Department of Public Safety within 90 days and register their vehicle within 30 days of moving. A visitor on a return ticket is unaffected and drives on the licence from home.

The scale, in hours
The single most useful thing to know about driving in Texas is that the state does not fit in a day.
| Drive | Time | What it means |
|---|---|---|
| Houston → San Antonio | About 3 h | The shortest of the big-city hops |
| Dallas → Austin | About 3 h 15 | I-35, busy on Friday evenings |
| Austin → Big Bend | About 6 h 30 | The last stretch has almost no services |
| Houston → El Paso | About 12 h | Further than Paris to Barcelona |
| San Antonio → New Orleans | About 8 h | Leaves the state on I-10 |
Houston, Dallas, Austin: freeway logic
Texas cities are built around fast freeways, and the frontage roads confuse visitors more than the traffic does.
Toll roads around Dallas, Houston and Austin are electronic and run by regional agencies, alongside the state-wide TxTag. Rental cars either carry a tag or are billed by plate afterwards, usually with a fee: ask at the counter before you take a toll road.
Frontage roads run parallel to the freeway on both sides and connect to it at intervals: useful for reaching a shop, easy to enter by mistake. If you miss an exit, take the next one and come back on the frontage road rather than reversing — the latter is illegal and common in rental-car horror stories.
Houston is the hardest to read: the loops and spurs are numbered separately from the interstates that run on them. Austin has the worst congestion for its size in the state; San Antonio is the calmest of the four. Parking is cheap everywhere compared with Europe — the cost of a Texas day is fuel, not parking.
Heat, storms and wildlife
The Texas climate is the other driver you have to plan around.
From June to September, afternoon temperatures pass 38 °C across most of the state. Air conditioning works hard, fuel consumption rises, and a breakdown on a rural road is dangerous rather than inconvenient — carry water. Spring brings hail and tornado warnings: if a warning is issued, the instruction is to leave the car and take shelter in a building, not to drive away from it.
On rural roads at dusk, watch for deer, feral hogs and, in the south, armadillos. In Big Bend, the drive from Marathon to the park entrance is 40 miles with nothing on it — fill up in Alpine or Marathon before you go in.
Renting a car
Book early for summer and holidays, compare one-way drop-off fees if you finish elsewhere, and check what insurance is already included before buying more at the desk. Most companies require a credit card in the main driver’s name, and drivers under 25 usually pay a surcharge. Our getting around guide compares car, plane, bus and train.
Driving in Texas: your questions
Can I drive in Texas on a European licence?
Yes, as a visitor. Texas requires a Texas licence from people who move there and register a vehicle; a holiday is driven on the licence from your country.
Where is the 85 mph road in Texas?
State Highway 130, the toll road that bypasses Austin to the east. It is the highest posted speed limit in the United States.
How long does it take to cross Texas?
About twelve hours from Houston to El Paso, and roughly thirteen on I-10 from Louisiana to New Mexico. It is not a day trip in either direction.
Do I need a toll tag in Texas?
Not strictly — the rental company can bill you by plate — but the administration fee per day usually costs more than a tag would. Ask at the desk if you plan to use the toll roads around Austin, Dallas or Houston.
