Understanding “Prima Facie” Evidence in Texas Speeding Tickets
Speeding Ticket Defense Lawyer
If you’ve received a speeding ticket in Texas, you might have heard the term “prima facie” in relation to the evidence against you. But what exactly does “prima facie” mean, how does it apply to speeding tickets, and crucially, how can you defend against it in court? This article aims to clarify the meaning of prima facie evidence in the context of Texas speeding laws. If you have been issued a speeding ticket and would like to discuss your options with an experienced speeding ticket attorney, feel free to contact our office at 214-321-4105.
Texas Speeding Laws: The Foundation
To understand “prima facie,” it’s essential to first look at the Texas statutes that govern speeding. There are two primary laws that outline the requirements for proving a speeding violation:
- Texas Transportation Code Section 545.351: Maximum Speed Requirement
- (a) An operator may not drive at a speed greater than is reasonable and prudent under the circumstances then existing.
- (b) An operator:
- (1) may not drive a vehicle at a speed greater than is reasonable and prudent under the conditions and having regard for actual and potential hazards then existing; and
- (2) shall control the speed of the vehicle as necessary to avoid colliding with another person or vehicle that is on or entering the highway in compliance with law and the duty of each person to use due care.
- (c) An operator shall, consistent with Subsections (a) and (b), drive at an appropriate reduced speed if:
- (1) the operator is approaching and crossing an intersection or railroad grade crossing;
- (2) the operator is approaching and going around a curve;
- (3) the operator is approaching a hill crest;
- (4) the operator is traveling on a narrow or winding roadway; and
- (5) a special hazard exists with regard to traffic, including pedestrians, or weather or highway conditions.

What this means: This statute establishes that driving at an “unreasonable and imprudent” speed is illegal, regardless of the posted speed limit. It emphasizes controlling your speed based on actual conditions and hazards.
- Texas Transportation Code Section 545.352: Prima Facie Speed Limits
- (a) A speed in excess of the limits established by Subsection (b) or under another provision of this subchapter is prima facie evidence that the speed is not reasonable and prudent and that the speed is unlawful.
What this means: This is where “prima facie” comes into play. It connects your actual speed to the “reasonable and prudent” standard.
What Does “Prima Facie” Mean Legally?
“Prima facie” is a Latin term that literally translates to “on its first appearance” or “at first face.” In a legal context, it has a more specific and powerful meaning:
- Sufficient Unless Contradicted: Prima facie evidence is that which is “sufficient as a matter of law to establish a given fact if it is not rebutted or contradicted.” (Rangel v. Rangel, 2024).
- Proof Until Disproven: It is evidence that, until its effect is overcome by other evidence, will suffice as proof of a fact in issue. In simpler terms, a prima facie case is one that will entitle a party to win if no evidence to the contrary is offered by the opposing party. (Texas Campaign for the Environment v. Partners Dewatering International, LLC, 2016).
- Minimum Quantum of Evidence: It represents the minimum amount of evidence legally necessary to support a rational inference that an alleged fact is true. (Id.).
Prima Facie Evidence as a “Rebuttable Presumption” in Speeding Cases
Prima Facie Evidence as a “Rebuttable Presumption” in Speeding CasesIn practice, for Texas speeding tickets, this means:
- Initial Sufficiency: If the prosecutor presents evidence (usually through the officer’s testimony) that you were driving above the posted speed limit, that alone is considered “enough” to establish that your speed was “not reasonable and prudent” and therefore “unlawful.” This establishes the prima facie case against you.
- The Burden Shifts: In most criminal cases, the State (prosecution) carries the entire burden of proof, meaning they must prove every element of the crime beyond a reasonable doubt. However, with a prima facie speeding ticket, once the State establishes that you were over the limit, the burden shifts to you (the defendant) to “rebut” or “contradict” that presumption.
- Rebuttable Presumption: This concept is known as a “rebuttable presumption.” It’s a legal assumption that holds true unless sufficient evidence is presented to disprove it. While rebuttable presumptions are more commonly seen in civil law, the Texas legislature has applied this to speeding cases.
How to Rebut the Prima Facie Presumption
The good news for defendants is that the standard for rebutting the prima facie presumption is lower than the State’s burden of proof.
- Your Burden: Preponderance of the Evidence: You only need to rebut the presumption by a preponderance of the evidence. This means you need to present evidence that makes it “more likely than not” that your speed, even if over the posted limit, was in fact “reasonable and prudent” under the specific conditions that existed at the time the ticket was issued.
- What Happens When You Rebut: Once you present enough evidence to discharge this burden, the legal presumption of “unreasonable and imprudent” speed disappears. It is no longer considered by the judge or jury as evidence of your guilt. The burden then fully shifts back to the State to prove your guilt beyond a reasonable doubt, without the benefit of that initial presumption.

Examples of evidence to rebut the presumption might include:
- Weather Conditions: Clear, dry roads; good visibility.
- Traffic Conditions: Light traffic, no congestion.
- Road Conditions: Wide lanes, good pavement, no construction or hazards.
- Time of Day: Day vs. night, peak vs. off-peak hours.
- Your Vehicle’s Condition: Well-maintained brakes, tires, etc.
- Officer’s Visibility/Conditions: Was the officer’s view obstructed? Were their speed-measuring device readings accurate given the conditions?
The Impact of Successfully Rebutting the Presumption

Successfully rebutting the prima facie presumption is a critical step in defending a speeding ticket.
- Presumption Disappears: As established by case law (though primarily in civil contexts, like In the Interest of Rodriguez), once the party against whom a rebuttable presumption is alleged offers contradicting evidence, “the presumption disappears and is not weighed or treated as evidence.”
- State’s Full Burden Restored: The effect of rebutting the presumption is that the State must then prove beyond a reasonable doubt that your speed was not reasonable and prudent, relying solely on the evidence they present, without the benefit of the automatic assumption that being over the limit made it unlawful.
It is crucial to emphasize to the judge or jury (during voir dire, opening statements, or closing arguments) that:
- The State initially met a low burden (prima facie evidence).
- You then met your burden (preponderance of the evidence) to rebut that initial presumption.
- Therefore, the burden shifts entirely back to the State to prove your guilt beyond a reasonable doubt, considering all evidence presented about the conditions at the time of the alleged offense.

Understanding and effectively applying the concept of prima facie evidence in a Texas speeding ticket case can be complex. An experienced speeding ticket attorney knows how to:
- Challenge the Officer’s Evidence: Question the accuracy of speed measuring devices, calibration records, and the officer’s methodology.
- Present Rebutting Evidence: Gather and present evidence about the road, weather, and traffic conditions that demonstrate your speed was reasonable and prudent.
- Articulate the Legal Argument: Clearly explain the “prima facie” and “rebuttable presumption” concepts to the judge or jury to shift the burden of proof back to the prosecution.
- Negotiate Outcomes: Work to secure a dismissal, deferred disposition, or defensive driving options to keep the ticket off your record.
Don’t assume that simply being clocked over the speed limit means you have no defense. Contact The Beltz Law Group today at 214-321-4105 to discuss your speeding ticket and let us help you fight for your driving record.
