OPINION
Opinion by
A jury convicted Omar Moreno of cocaine possession. 2 The trial court sentenced him to ten years confinement in the Institutional Division of the Texas Department of Criminal Justice, assessed a $1,500 fíne, suspended the sentence, and placed him on community supervision for ten years. In three issues, Moreno: (1) challenges the trial court’s denial of his motion to suppress; (2) asserts that the evidence used to convict him was the product of an illegal arrest; and (3) claims that the evidence .was obtained through an illegal search and seizure. We affirm.
/. FACTUAL AND PROCEDURAL BACKGROUND
A. Introductory Facts
On September 22, 2000, Moreno and a passenger were traveling westbound in medium-to-heavy traffic on Alton Gloor Boulevard in Brownsville, Texas. Moreno was driving a green 1996 Ford Taurus. A Brownsville police officer pulled Moreno over, then called for back-up. The arresting officer testified he stopped Moreno for: (1) impeding traffic; (2) window tinting in excess of state regulations; and (3) a faulty courtesy brake light. When the arresting and back-up officers approached Mоreno’s car, both officers looked through the car’s open windows and saw the passenger kick a black object under the front passenger seat. In response to the arresting officer’s request, Moreno presented a recently expired driver’s license. He did not produce proof of insurance. The officer placed Moreno under arrest. The back-up officer arrested the passenger on outstanding warrants.
The officers inventoried the рassenger compartment of Moreno’s car at the scene. They found a black bag under the front passenger seat. When the arresting officer asked Moreno what was in the bag, he replied, “Personal items.” He refused to consent to a search of the bag. He asked if the officers had a warrant. The officers opened the bag. Inside they found cocaine, scales, and other drug paraphernalia. At the police station, Moreno signed a cоnfession admitting that the cocaine belonged to him.
B. Preservation of Error
We first address the State’s suggestion that Moreno waived his complaint by stipulating to a chemical analysis of the cocaine and to the chain of custody. Moreno filed a pre-trial motion to suppress the cocaine and his confession as the products of an illegal detention, arrest, and search. Although it is not clear from the record, the trial court apparently carried the suppression motiоn with the trial. While the record reflects that Moreno stipulated to the analysis and chain of custody of the cocaine, he did so subject to his suppression motion. He also objected at trial on the same basis to admission of the stipulation into evidence. The trial court overruled Moreno’s objection and admitted the stipulation. It held a suppression hearing outside the presence of the jury during a *343 later break in the trial. 3 It then admitted Moreno’s confession into evidence.
1.The Trial Court’s Rulings
No written order denying the suppression motion appeаrs in the record. However, the trial court rendered the following findings of fact and conclusions of law:
The Court finds, first, that the defendant was lawfully arrested for traffic violations, that there was no one to take the vehicle and necessitating an inventory, that inventory search revealed marijuana-I’m sorry, cocaine, that the defendant was also arrested for possession of cocaine.
We hold that these findings reflect the trial court’s implicit ruling denying Moreno’s suppression motion.
See
Tex.R.App. P. 83.1(a)(2)(A);
see also Gutierrez v. State,
Later, in the presence of the jury, Moreno reasserted his objection when the State offered his statement into evidence. The trial court overruled the objection. Moreno renewed his motion to suppress after the close of all the evidence, which the trial court also overruled.
2.Waiver Principles
A motion to suppress is a specialized objection to the admissibility of evidence.
Morrison v. State,
3.Waiver Analysis
The record reflects that the trial judge was fully aware of the basis on which Morenо asserted that the cocaine and statement should be suppressed.
See Morrison,
II. BURDENS OF PROOF AND STANDARD OF REVIEW
A. The Burdens of Proof
An accused seeking to suppress evidence on the basis of illegal police conduct bears the burden of proof to rebut a presumption of proper police conduct.
See McGee v. State,
B. The Standard of Review
At a suppression hearing, the trial court is the sole finder of fact.
Arnold v. State,
We uphold a trial court’s ruling on a suppression motion if it is reasonably supported by the record and is correct on any theory of law applicable to the case.

III. ANALYSIS
A. Investigative Detention
1. The Evidence
The arresting officer testified as follows:
A. First thing that caught my attention was I noticed that traffic was a little bit backed up on Alton Gloor, and you have two lanes of traffic, both going west bound, which the lanes were there. And the right hand lane, it was kind of backed up and was a lot of congestion, so when I looked to see what was causing the congestion, there was the green Ford Taurus that was going about 25 miles an hour on Alton Gloor Boulevard.
Q. And there was traffic backed up behind him?
A. Yes, sir.
Q. Did you notice that traffic having to do anything in regards to that vehicle?
A. The traffic, they had to go over into the left hand lane of traffic, which is also west bound, and go around it. And that was kind of difficult because of the amount of traffic that there was at the time in both lanes.
Q. When you say they had to go around it, were they making normal passes, or was traffic backing up?
A. Traffic was backing up. They had to wait for an opening in the traffic to get around it.
Q. Okay. Did you get any closer to that vehicle?
A. Yes, sir, I got right behind the vehicle.
Q. Did you notice anything when you got right behind the vehicle?
A. I noticed the window tint on the vehicle was extremely dark. Also I noticed when I got behind the vehicle, the driver of it would be, applied the brakes, I could tell that two bottom brake lights came on. The vehicle also has the top brake light on the, I guess, above the back glass, and it didn’t activate. So that vehicle, that light was out.
Q. All right. Now, when you saw what you have described here, do any of those conditions violate the laws of Texas?
A. Yes, sir, the window tint, we do have a regulation, 35 percent on the window tinting.
Q. And are you trained to recognize that?
A. Yes, sir, we recognize it by sight, and we also have tint meters that normally we would have issued to us to measure the аmount of window tint.
Q. And have you looked into tint before as far as—
A. Yes, sir.
Q. —checking out on citations?
A. Yes, sir.
Q. What about the 25 miles an hour, is it itself a violation?
A. No, sir, going 25 miles an hour is not a violation. However, if you are impeding traffic, then that becomes a violation.
*346 [[Image here]]
Q. What is the speed limit there?
A. I believe it’s 45 miles an hour, sir.
Q. Okay, so this vehicle is traveling 25?
A. Yes, sir.
Outside the presence of the jury, Moreno testified that the location was a construction zone where the speed limit was 35 miles per hour. He also said he had just passed through a school zone and was traveling about 30 miles per hour. The passenger corroborated Moreno’s testimony. The car’s window tint, Moreno testified, was the same as it had been straight from the car dealership.
The arresting officer admitted he did not have a tint meter with him. Thus, he did not determine if the tint actually exceeded that permitted by law. The officer agreed that both of Moreno’s brake lights were operating. He conceded that an inoperable courtesy brake light does not violate the law.
2. The Law of Investigative Detention
Stopping an automobile and detaining its occupants is a “seizure” within the meaning of the Fourth Amendment.
Morrison,
3. Review of the Trial Court’s Application of the Law of Investigative Detention to the Facts
It is undisputed that the Brownsville police officers did not have a warrant to arrest Moreno or search his car. Thus, it was the State’s burden at the suppression hearing to show by a preponderance of the evidence that the arresting officer had at least a reasonable suspicion that Moreno either had committed an offense or was about to do so before he stopped Moreno.
See McGee,
The question then becomes whether these facts, when viewed de novo, are sufficient to establish a violation of the law.
See Morrison,
An operator may not drive so slowly as to impede the normal and reasonable movement of traffic, except when re *347 duced speed is necessary for safe operation or in compliance with the law.
Tex. TRAnsp. Code Ann. § 545.368(a) (Vernon 1999);
Richardson,
In
Richardson,
testimony at the suppression hearing and a videotape of the traffic stop established “that there was little or no traffic on the road for appellant to impede and what traffic thеre was, had no difficulty in passing.”
Richardson,
In thе absence of similar evidence in this case showing the actual speed limit, the trial court’s resolution of conflicting evidence based on an evaluation of the relative credibility and demeanor of the witnesses was necessary.
See Richardson,
B. Warrantless Arrest
1. The Evidence
Moreno also contested whether his license had expired. He testified he told the officer he had sent in a renewal of his driver’s license, which had expired on September 10, 2000, a fеw days before. He argued that the officers should have performed a license cheek before arresting him, which would have verified that his license had been renewed. However, the temporary license Moreno introduced in support of his suppression motion showed that it was valid beginning October 4, 2000, after the date of his arrest on September 22, 2000.
Also disputing the officer’s testimony that Moreno could not produce proof of insurance, Moreno testified the officer re *348 fused to permit him to retrieve his proof of insurance from the glove box. The passenger confirmed that Moreno tried to get into the glove box but was stopped by the officer. Further, Moreno introduced an automobile insurance binder for a 1996 Taurus that showed insurance in effect on September 22, 2000. However, the trial court ruled:
Gentlemen, first, before I forget it, I think the defense — -the State’s objection has gone to it, but I am not real sure. The reason the Court has nоt received the Exhibit 4 at this time is when the Court reviewed that, it appears to be, number one, from a relevance standpoint, it’s a questionable relevance because the relevant thing would be whether he had it at the time. But secondly, it appears to be a, what I would call a bill from the company saying this is what we are going to do, it does not appear to be any proof of that in fact he was insured, which is what I am understanding it’s being offered to show that well, maybe he didn’t have it or whatever, but he really was insured, I am not sure it provides any proof that he was in fact insured at that time because it just simply, it proves that some time in the past he apparently had insurance and they were providing a renewal some couple of months earlier, but it does not show that he ever in fact followed through and did whatever you have to do to pay for it and get the insurance in place. So it’s one, not a policy of insurance, and two, it’s certаinly not proof of insurance on the proper form that we are required to carry around in our car. I’ll still keep the issue open depending on how the evidence materializes later on.
Finally, Moreno introduced evidence that his citations for driving without a license and not having proof of insurance were dismissed for want of prosecution. He argued that the State was collaterally estopped from relying on proof of those violations to justify the arrest and search.
2. The Law of Warrantless Arrests
After initiating a valid investigative detention for a traffic offense, a peace officer may then make an arrest if the officer discovers another offense during the investigation.

3. Review of the Trial Court’s Application of the Law of Warrantless Arrests to the Facts
It was the State’s burden at the suppression hearing to show by a preponderance of the evidence that the arresting officer had probable cause to arrest More
*349
no.
See McGee,
C. Warrantless Seizure
1. The Testimony
Moreno also disputed that im-poundment of his car was necessary. The arresting officer agreed that a check of the outstanding warrants on the passenger showed he was not the person named in the warrants, and the passenger was released. The passenger testified and disputed the officers’ testimony that he did not have a driver’s license with him that day. Moreno introduced evidence of the passenger’s valid driver’s license on that date. Hе argued that the officers were required to release the car to the passenger rather than impound it. He concluded that the resulting inventory search was therefore illegal.
We need not decide these issues. We find that the officers’ search of the black bag they observed the passenger kick under the front seat was a search incident to a lawful custodial arrest.
See Williams v. State,
2. The Law of Search Incident to Arrest
The privacy interests of a person who has been lawfully arrested must yield, for a reasonable timе and to a reasonable extent, to permit the police to search for weapons, means of escape, and
*350
evidence.
Oles v. State,
3. De Novo Application of the Law of Search Incidеnt to Arrest
We find that the officer’s arrest of Moreno for driving with an expired license and no proof of insurance authorized a search of the black bag under the front passenger seat as a search incident to Moreno’s arrest.
See Welch,
IV. CONCLUSION
Having overruled each of Moreno’s issues, we affirm the judgment of the trial court.
Notes
. See Tex. Health & Safety Code Ann. § 481.112 .(Vernon 2002).
. At the same time, the trial court conducted a hearing on the voluntariness of Moreno’s confession on grounds unrelated to this appeal. Moreno does not challenge on appeal the trial court’s ruling that his statement was voluntary.
. Similarly, the State’s standard for proving the voluntariness of an accused's confession is preponderance of the evidence.
