The highest speed limit in Texas is 85 mph, and you’ll find it on exactly one road: a 41-mile section of State Highway 130 between State Highway 45 south of Austin and Interstate 10 east of Seguin. That posting makes it the fastest legal speed on any public road in the United States.1Texas Department of Transportation. Setting Speed Limits – Section: Maximum Speed Limit
The 85 MPH Stretch of SH 130
The road carrying the 85 mph limit is a limited-access rural toll road known as Segments 5 and 6 of State Highway 130, built by a private consortium and operated by SH 130 Concession Company. It was designed as a high-speed bypass to pull traffic off Interstate 35 between Austin and San Antonio.
The Texas Transportation Commission authorized the 85 mph posting in 2012. Before that, no public road in the country was signed above 80 mph. The commission approved it only after engineering and traffic studies concluded the speed was safe and reasonable for how the road was built.
Why 85 MPH Is Only Posted There
Texas law ties any posting above the statutory default to the physical design of the highway, and most roads don’t meet the engineering characteristics an 85 mph zone requires. The next tier down is 80 mph, which the Transportation Commission has authorized on segments of Interstate 10 and Interstate 20 in ten designated West Texas counties.1Texas Department of Transportation. Setting Speed Limits – Section: Maximum Speed Limit The commission can also authorize 75 mph on roads built to that standard.
Default Speed Limits Everywhere Else
Outside those posted high-speed corridors, Texas sets default limits by road type and surroundings. These are “prima facie” limits, meaning exceeding them is treated as evidence you were driving faster than conditions allowed.2State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits The main ones:
- Urban streets: 30 mph, and 15 mph in alleys
- Numbered highways outside urban areas (including farm-to-market and ranch-to-market roads): 70 mph
- Unnumbered highways outside urban areas: 60 mph
- School buses on numbered highways: 60 mph if the bus has passed a commercial vehicle inspection, 50 mph otherwise
These apply unless a different speed is posted after an engineering study.
What a Speeding Ticket Actually Costs
A standard speeding ticket in Texas is a Class C misdemeanor. The base fine written into state law runs from $1 to $200, but the number you pay is higher once a mandatory $50 state traffic fine and the legislature’s court costs are added on.3State of Texas. Texas Transportation Code 542.401 – General Penalty A routine ticket typically ends up between $150 and $300 depending on how fast you were going and which court handles it.
Insurance is often the bigger hit. According to the Insurance Information Institute, auto insurance premiums increase an average of at least 20 percent for three years after a speeding conviction.
Construction Zones and School Zones
Speeding in a construction or maintenance zone with workers present doubles both the minimum and maximum fine. The citation itself has to note that workers were present for the doubled penalty to apply.4State of Texas. Texas Transportation Code 542.404 – Fine for Offense in Construction or Maintenance Work Zone School zones carry similarly elevated fines, with amounts set by the municipality. A single ticket in either zone can easily top $400.
Your License
Texas doesn’t currently operate a point system for speeding tickets, and the Driver Responsibility Program that used to add surcharges was repealed in 2019.5Texas Department of Public Safety. Driver Responsibility Program Volume still matters, though. Four or more moving violations within 12 months, or seven within 24 months, can lead to a license suspension.6Texas Department of Public Safety. Traffic Offenses
Dismissing a Ticket With a Driving Safety Course
Most drivers get a once-a-year opportunity to have a speeding ticket dismissed by completing a state-approved driving safety course. You plead no contest or guilty, pay court costs, and finish the course by the court’s deadline; if you do, the charge is dismissed and stays off your driving record. You’re ineligible if you were going 25 mph or more over the limit, you hold a commercial driver’s license, the offense happened in a construction zone with workers present, or you already used the dismissal option in the past 12 months. You also need a valid Texas license and proof of insurance when you make the request.7State of Texas. Texas Code of Criminal Procedure Article 45.0511 – Driving Safety Course Dismissal
When Speed Becomes Reckless Driving
Texas does not set a specific mph figure that automatically turns a speeding ticket into a reckless driving charge. Reckless driving is a separate offense defined as driving with willful or wanton disregard for the safety of people or property, and a prosecutor would have to show behavior that went past simply exceeding the limit.8State of Texas. Texas Transportation Code 545.401 – Reckless Driving Offense The stakes jump a lot if the charge sticks. A basic speeding ticket is a Class C misdemeanor with no jail time. Reckless driving carries up to a $200 fine, up to 30 days in county jail, or both, and it reads as a criminal offense on a background check rather than a traffic citation.
