Texas has a maximum speed limit of 70 mph (with some highways allowing up to 85 mph), but drivers must always adjust their speed for weather, traffic, and road conditions. There is no minimum speed limit, though driving too slowly and impeding traffic can result in fines, and drivers must slow down or move over for emergency and work vehicles.
Speeding is strong evidence of negligence in a personal injury case, and if you’re injured by a speeding driver, you may be entitled to compensation for medical bills, lost wages, and other damages.

Maximum Speed Limits
Texas has a maximum established speed limit of 70 miles per hour, according to the Texas Department of Transportation (TxDOT)1.
TxDOT allows local city and state governments to adjust the speed limit up to 85 mph in areas where highway design supports higher speeds.
Drivers Must Adjust Speed to Driving Conditions
Texas Transportation Code §545.351 requires drivers to adjust their speed to accommodate real-time conditions, such as:
- Adverse weather and its impact on road surfaces
- Heavily trafficked areas
- Construction zones
- Accident scenes
The basic speed limit rule establishes a maximum driving speed under normal road conditions.
The law indicates that individuals must drive at speeds that are reasonable and safe, taking into account the immediate environment.
Failing to drive at a reasonable and safe speed can be considered reckless driving in Texas.
No Minimum Speed Limit in Texas
There are no speed limit laws in Texas establishing a minimum speed limit.
However, drivers cannot operate a vehicle at a speed that impedes the normal and reasonable flow of traffic, as stated in Texas Transportation Code §545.363.
Transportation Code also establishes these slower speed limits in specific areas and for certain vehicles:
- 30 mph on streets in urban areas
- 15 mph in alleyways
- 15 mph on beaches
- 60 mph for school buses passing specific motor vehicle inspections
- 50 mph for school buses not passing specific inspections or traveling on highways not numbered by the US or the state
Impeding traffic flow by driving too slowly in the left lane can create traffic hazards. Obstructing traffic may also result in fines up to $200.
Variable Speed Limits
TxDOT’s implementation of a variable speed limit (VSL) (Pg. 4)2 allows real-time road data to be collected and used to adjust speed limits temporarily based on driving conditions.
The speed limit at the time of a car accident in a variable speed zone will play a role in determining negligence in a Texas car accident.
The TxDOT El Paso District is one of the first cities in Texas to use VSL to lower speed limits by up to 10 mph below the posted speed limits.
The VSL system in El Paso is located on US 54, between Cassidy Road and I-10, on the southbound lanes.
VSL strives to minimize car accidents in Texas, where localized events can suddenly impact traffic. VSL is the result of a 133-car pile-up on I-35 in Fort Worth, resulting in the death of 6 individuals, according to an investigation by the National Transportation Safety Board (NTSB)3.
Move Over or Slow Down Laws
Drivers who cause serious injuries when failing to move over or slow down upon encountering workers along the roadside now face significant fines and even jail time.
The law aims to protect emergency responders, roadside workers, construction zone crews, animal control officers, and law enforcement personnel working in areas with high traffic volumes.
Updates to the law require drivers to:
- Move out of the lane closest to work vehicles and workers on the side of the road
- Reduce speeds to 20 mph below the speed limit when switching lanes is not possible
- Slow down to 5 mph when speed limits in an area are 25 mph or less
- Remain on the lookout for tow trucks, utility service workers, animal control officers, and parking enforcement employees
Fines for the first offense range up to $1,250. Drivers may face fines of up to $4,000 and potential jail time for causing a serious injury or death. Speeding is a significant factor4 in accidents occurring in Texas work zones.
School Zone Speed Limits
School zone speed limits are generally set at a minimum speed. Local municipalities have the authority to adjust school zone speed limits according to a community’s specific needs. Speed limits may decrease to as low as 15 mph. The following fines and penalties may apply for violating Texas school zone speed limits:
- Doubled fines
- Up to $200 in fees for using a cell phone in an active school zone
- An additional $25 court fee
Regardless of your speed, failing to stop for a school bus in Texas can cost drivers up to $1250 in fines.
Drivers can face a license suspension.
Jail time may occur depending on the severity of the incident and other convictions on a driver’s record.
Speed Limit Exceptions
Emergency vehicles responding to an incident may potentially exceed the speed limit as long as they do not present a danger to others. Each municipality within Texas can establish ordinances creating specific speed limits for responders.
The right to exceed the speed limit in emergencies is not unlimited. Responders still must exercise reasonable caution when using excessive speeds (Texas Transportation Code §545.365).
Speeding Accidents and Liability
Violating these laws is most often a small civil offense that results in a citation or ticket, but it can have more lasting consequences.
Speeding is more than just a traffic violation. It is strong evidence of negligence in a personal injury case.
When a driver exceeds the speed limit or drives too fast for conditions, they have breached their duty of care to others on the road.
Under Texas law, a speeding violation can be used to prove negligence in a personal injury case if that violation caused an accident and resulting injuries.
Insurance companies and defense attorneys often try to shift blame or minimize liability, but establishing that a driver was speeding can significantly strengthen a victim’s claim for compensation.
If you were injured in an accident caused by a speeding driver, you may be entitled to recover medical expenses, lost wages, and other damages. It’s important to speak with an accident lawyer as soon as possible because the car accident statute of limitations in Texas is strictly enforced.
An experienced personal injury attorney can help gather evidence such as skid marks, witness statements, and vehicle data to prove that speeding was the cause of the crash.
Newer Speed Limit Laws Impact Some Texas Neighborhoods
Municipalities in Texas recently gained the right to lower speed limits in neighborhoods when local governing bodies determine that the current speed limit is unsafe, under companion bills H.B. 5253 and S.B. 2725, known as the Safe Neighborhood Streets bill.
Decreasing speed limits below 20 mph is not allowable.
No highway studies are necessary to implement these changes.
Understanding Texas speed regulations is essential for safe driving and avoiding violations. This reference table summarizes key speed limits across different road types and situations.
| Location/Vehicle Type | Standard Speed Limit | Key Exceptions & Notes |
|---|---|---|
| Highways (Maximum) | 70 mph | Up to 85 mph on designated roads with appropriate engineering studies |
| Urban Streets | 30 mph | Lower limits may apply in school zones, business districts, or residential areas |
| Alleyways | 15 mph | No exceptions – standard statewide |
| Beaches | 15 mph | Local ordinances may establish different limits on specific beaches |
| School Buses (inspected) | 60 mph | Applies only on US/state numbered highways when passing specific inspections |
| School Buses (uninspected) | 50 mph | Applies to all roads for buses not passing inspections or not on numbered highways |
| School Zones | Varies (Typically 15-25 mph) | Active during specific hours; fines are doubled for violations |
| Work Zones | Posted limit | Move Over law requires reducing speed by 20 mph below limit or changing lanes |
| Neighborhood Streets | 30 mph (default) | Municipalities can now lower to 20 mph under Safe Neighborhood Streets bill |
| Variable Speed Limit Zones | Adjusted in real-time | Can be lowered by up to 10 mph below posted limits based on conditions |
