The residential speed limit in Texas is 30 miles per hour by default, and it applies on any neighborhood street that qualifies as an “urban district” under state law, whether or not a speed limit sign is posted.1State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits Alleys have their own 15 mph default under the same statute, and cities can lower the neighborhood limit to 25 or even 20 mph if they post signs to that effect.
When the 30 MPH Default Applies
The 30 mph figure comes from Texas Transportation Code § 545.352, and it kicks in automatically anywhere the road runs through an “urban district.” The statute defines an urban district as a stretch of road where buildings used for homes, businesses, or industry sit less than 100 feet apart for at least a quarter mile on either side.1State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits Most established neighborhoods clear that bar without difficulty. If houses line both sides of the street without noticeable gaps, the road is an urban district and 30 mph is the ceiling.
Alleys are treated separately. The prima facie limit there is 15 mph, and again no sign is required for the rule to apply.1State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits Alleys feel casual, but the limit is statewide and enforceable.
What “Prima Facie” Means for Your Ticket
Both the 30 mph and 15 mph figures are “prima facie” limits. Exceeding either one creates a legal presumption that you were driving at an unsafe speed, and the burden shifts to you to explain why your speed was reasonable under the conditions.1State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits
It works in the other direction too. Even at 25 in a 30 zone, an officer can cite you if children are near the street, visibility is poor, or some other hazard makes that speed unreasonable.2State of Texas. Texas Transportation Code 545.351 – Maximum Speed Requirement The posted number is a ceiling, not a guarantee.
When a City Lowers the Limit
A city can drop the residential limit below 30 mph. Under Texas Transportation Code § 545.356, a municipal governing body may lower the speed limit to 25 mph on two-lane, undivided streets that aren’t part of the state highway system without conducting an engineering and traffic study first.3State of Texas. Texas Transportation Code 545.356 – Authority of Municipality to Alter Speed Limits Cities can go as low as 20 mph on qualifying residential streets under the same authority.4Texas Department of Transportation. Procedures for Establishing Speed Zones
Any lowered limit only takes effect once the city passes an ordinance and posts signs.3State of Texas. Texas Transportation Code 545.356 – Authority of Municipality to Alter Speed Limits So the sign rule is opposite to the state default: the 30 mph and 15 mph state limits need no signage, but a 25 mph neighborhood limit does. If your street has no posted sign and you’re ticketed at 28, the default 30 mph controls and you were under it.
What a Residential Speeding Ticket Costs
State law caps the base fine for a standard speeding violation at $200.5State of Texas. Texas Transportation Code 542.401 – General Penalty What you actually pay is higher, because court costs are added on top and the totals vary by jurisdiction. In Bexar County, a ticket for 1–10 mph over comes to $190, and 31 or more mph over reaches $336.6Bexar County, TX – Official Website. Ticket Fine Schedule Harris County starts at $135 for 1–10 mph over and rises to $280 for 39 or more over.7Harris County Justice Courts. Fines for Speeding Tickets
Insurance is the longer-term cost. A single speeding conviction raises Texas premiums by roughly 7% on average, which works out to about an extra $175 per year on the average policy for as long as the violation stays on your record.
Construction Zones Double the Fine
If a residential street is under active construction with workers present, fines double automatically. Texas Transportation Code § 542.404 requires courts to apply twice the minimum and twice the maximum fine for any traffic violation in a work zone with workers on site. A ticket that would run $200 can climb past $400. The doubling only applies while workers are actually there. Cones without a crew mean standard fines.
How Convictions Affect Your Driver’s License
Texas no longer uses a point system. The Driver Responsibility Program that assigned points to convictions was repealed effective September 1, 2019.8Department of Public Safety. Driver Responsibility Program Websites still describing two- or three-point penalties are outdated.
The current rule is a straight conviction count. The Department of Public Safety will suspend your license if you accumulate four or more moving violations within any 12-month period, or seven or more within 24 months.9Department of Public Safety. Traffic Offenses Each speeding ticket counts as one moving violation.
What Happens If You Ignore the Ticket
A missed court date starts a chain reaction. The court will issue an arrest warrant, and in some jurisdictions a failure-to-appear charge adds its own fine — $244 in Houston’s municipal courts, for example. Warrant fees stack on top. As of January 1, 2026, Houston’s warrant fee is $75, with additional fees for offenses on or after September 1, 2025.10City of Houston Municipal Courts Department. Consequences of Neglecting a Ticket
The Department of Public Safety can also block you from renewing your driver’s license or vehicle registration through its Failure to Appear/Failure to Pay program. That hold stays in place until you clear every outstanding case and pay a $10 DPS notification fee for each one.11Department of Public Safety. Failure to Appear/Failure to Pay Program If the case goes to collections, expect roughly 30% added on top of what you already owe. A $190 ticket can push past $500 without much effort.
Keeping the Ticket Off Your Record
Texas gives drivers two routes to avoid a conviction: a driving safety course and deferred disposition.
Driving Safety Course
Under Texas Code of Criminal Procedure Article 45.0511, a judge can dismiss your ticket if you complete an approved defensive driving course. You have to plead no contest or guilty, hold a valid Texas license, show proof of insurance, and pay the court costs upfront. You are ineligible if you were clocked at 25 mph or more over the posted limit, if you hold a commercial driver’s license, or if you’ve already used this option on another ticket within the past 12 months.12State of Texas. Texas Code of Criminal Procedure Art 45.0511
The 25 mph threshold matters on residential streets in particular. Doing 56 in a 30 zone puts you 26 over, and the driving safety course option is gone.
Deferred Disposition
Deferred disposition works differently. The judge sets conditions — often a defensive driving course, community service, or similar requirements — and if you complete them within a set period, the case is dismissed.13State of Texas. Texas Code of Criminal Procedure Article 45.051 Deferred disposition is discretionary. You can request it, but the judge decides.
A successful deferral leaves no conviction on your record. No insurance hike, no moving violation counted toward the suspension thresholds. Fail to meet the conditions and you’re convicted and sentenced as though the deferral never happened, so the deadlines and requirements have to be taken seriously.
