Brian Joseph Bellnoa and Jeremiah J. Bellnoa, both minors, were injured when they were struck by a privately owned and operated truck while attempting to cross the street in the 3500 block of East First Street in Austin. Brian Joseph Bellnoa later died from his injuries. Appellants Jose Bellnoa and Carolyn Bellnoa (the Bellnoas) sued ap-pellee the City of Austin (the City) for damages arising out of that accident, alleging various acts of negligence relating to the regulation of traffic. 1 The trial court rendered summary judgment in favor of the City on the basis that the City was protected from liability by sovereign immunity. The Bell-noas appeal, bringing three points of error. We will affirm the trial court’s judgment.
I. THE RELEVANT STATUTES
A municipality is immune from liability for its governmental functions in the absence of a statute waiving sovereign immunity.
2
Wenzel v. City of New Braunfels,
A governmental unit in the state is liable for:
(1) property damage, personal injury, and death proximately caused by the wrongful act or omission or the negligence of an employee acting within his scope of employment if:
(A) the property damage, personal injury, or death arises from the operation or use of a motor-driven vehicle or motor-driven equipment; and
(B) the employee would be personally liable to the claimant according to Texas law; and
(2)personal injury and death so caused by a condition or use of tangible personal or real property if the governmental unit would, were it a private person, be liable to the claimant according to Texas law.
Section 101.0215 further provides that:
(a) A municipality is hable under this chapter for damages arising from its governmental functions, which are those functions that are enjoined on a municipality by law and are given it by the state as part of the state’s sovereignty, to be exercised by the municipality in the interest of the general public, including but not limited to:
(3)street construction and design ...
(20) warning signals ...
(21) regulation of traffic ...
(31) maintenance of traffic signals, signs, and hazards....
However, section 101.056 excepts from the waiver claims arising from discretionary acts 3 and omissions, providing:
This chapter does not apply to a claim based on:
(1) the failure of a governmental unit to perform an act that the unit is not required by law to perform; or
(2) a governmental unit’s decision not to perform an act or on its failure to make a decision on the performance or nonperformance of an act if the law leaves the performance or nonperformance of the act to the discretion of the governmental unit.
Section 101.060 additionally excepts from the waiver claims arising from the placement or condition of traffic or road control devices in certain circumstances:
*824 (a) This chapter does not apply to a claim arising from:
(1) the failure of a governmental unit initially to place a traffic or road sign, signal, or warning device if the failure is a result of discretionary action of the governmental unit;
(2) the absence, condition or malfunction of a traffic or road sign, signal, or warning device unless the absence, condition, or malfunction is not corrected by the responsible governmental unit within a reasonable time after notice; or
(3) the removal or destruction of a traffic or road sign, signal, or warning device by a third person unless the governmental unit fails to correct the removal or destruction within a reasonable time after actual notice.
II. LIABILITY FOR DESIGN AND CONSTRUCTION
In their first point of error, the Bellnoas assert that the trial court erred in granting the City’s motion for summary judgment because the City can be held liable for the design and construction of the street upon which the accident occurred. The Bellnoas’ second amended petition does not describe a specific construction or design flaw, but it appears from their answers to interrogatories, which were filed with the City’s motion for summary judgment, that the “design flaws” complained of involved the City’s failure to install allegedly appropriate traffic signals and crosswalks. The claim that a design defect existed, then, is simply a claim for that the City failed to initially install traffic signals and crosswalks. Therefore, we will discuss this point of error below in conjunction with the second point of error.
III. LIABILITY FOR DECISION WHETHER TO PLACE TRAFFIC CONTROL DEVICES
In their second point of error, the Bellnoas allege that the trial court erred in granting the motion for summary judgment because the City of Austin can be held liable for its decision whether to place traffic control devices. Under section 101.060(a), a governmental unit is not liable for the failure to initially place a traffic or road sign, signal, or warning device if the failure is a result of the discretionary action of the governmental unit. The question of whether an act is discretionary is one of law.

State Department of Highways and Public Transportation v. King,
IV. LIABILITY FOR RAISING THE SPEED LIMIT
In their third point of error, the Bell-noas allege that the City was negligent in raising the speed limit from 30 to 40 miles per horn". A threshold issue is whether the alleged problem resulted from the decision to increase the speed limit from 30 to 40 miles per hour or whether it resulted from the sign displaying that limit. We hold that the source of the alleged problem is the City’s decision to raise the speed limit.
In so holding, we decline to follow the decision in
Garza v. State,
The court in
Garza
based its decision primarily
6
on its reading of
Sparkman v. Maxwell,
In
Alvarado v. City of Lubbock,
Since this case cannot be analyzed as a problem attributable to a traffic signal, the next issue is whether the Tort Claims Act waives the City’s immunity for its decision to raise the speed limit. The Bellnoas claim that the City’s immunity was waived by sec *826 tion 101.0215. The City’s act of raising the speed limit falls under section 101.0215, which provides that a city is liable under the Tort Claims Act for damages arising from the regulation of traffic. However, we must also consider whether section 101.0215 is an independent waiver of immunity or whether it is subject to the conditions in section 101.021.
Section 101.0215 provides that a “municipality is liable under this chapter for damages arising from its governmental functions.” Section 101.0215 then lists thirty-three different governmental functions, including the regulation of traffic. Several Texas courts have held that section 101.0215 is not a waiver of immunity because the words “under this chapter” limit the liability of the municipality for the listed functions under section 101.0215 to the conditions required under section 101.021.
See Alvarado v. City of Brownsville,
A waiver of sovereign immunity must be clear and unambiguous.
University of Tex. Medical Branch v. York,
Therefore, to determine whether a municipality may be held liable for governmental functions listed in section 101.0215, we must first determine whether the alleged harm meets the conditions of section 101.021, and must then determine whether governmental immunity is preserved because the act involves discretion that is committed to the government under section 101.056.
Under section 101.021, the government is liable for (1) property damage, personal injury, or death arising from the use and operation of a vehicle or (2) personal injury and death caused by a condition or use of tangible personal or real property if the governmental unit would, were it a private
*827
person, be liable to the claimant according to Texas law. This case does not involve the operation or use of a motor vehicle under section 101.021(1) because the vehicle involved was not used or operated by an employee of the City.
Luna v. Harlingen Consol. Indep. Sch. Dist.,
The Texas Supreme Court recently affirmed this interpretation of section 101.021(1) in
LeLeaux v. Hamshire-Fannett Indep. Sch. Dist.,
“The phrase, ‘arises from,’ requires a nexus between the injury negligently caused by a governmental employee and the operation or use of a motor driven vehicle or piece of equipment. While the statute does not specify whose operation or use [of motor driven vehicles or equipment] is necessary — the employee’s, the person who suffers injury, or some third party — we think the more plausible reading is that the required operation or use is that of the [government] employee.”
Id. at 51.
Additionally, the act of changing the speed limit does not appear to involve the condition or use of tangible personal or real property, even if the decision to change the ordinance is reduced to paper.
See Robin-son v. City of San Antonio,
Finally, the decision to raise the speed limit is a decision committed to the City’s discretion under section 101.056.
Eakle v. Texas Dep’t of Human Servs.,
The judgment of the trial court is affirmed.
Notes
. The Bellnoas also sued the driver of the truck. The driver settled with the Bellnoas and is not a party to this appeal.
. However, a municipality is liable for its proprietary functions without a statutory waiver.
Wenzel v. City of New Braunfels,
.Although section 101.056, on its face, applies only to failures to act and omissions, the section has been judicially interpreted also to except positive acts of governments from liability under the Tort Claims Act if those acts are discretionary.
See, e.g., Christilles v. Southwest Tex. State Univ.,
. The Bellnoas do not explicitly state the basis of the mandatory duty in their pleadings, in their reply to the motion for summary judgment, or in their appellate brief, but did ask the trial judge to take judicial notice of these documents in their reply to the motion for summary judgment.
. For other cases holding that the Manual on Uniform Traffic Control Devices does not establish a mandatory duly to install particular traffic control devices, see
Dunn v. City of Tyler,
. The court in
Garza
also quoted language from
City of San Antonio v. Schneider,
. The City urges that Shives is dispositive of this case. However, we must analyze this case further since the plaintiff in Shives did not claim that section 101.0215 is an independent waiver of immunity. This case also requires further analysis since Shives involved a failure to lower a speed limit, which falls within the plain language of section 101.056, while this case involves the positive act of raising the speed limit, which must be analyzed under the case law interpreting discretionary acts.
. However, note that persons who suffer property damage that was once compensable because the claim arose from a proprietary act of the municipality are now without a remedy if the act was reclassified as a governmental act and the property damage was not caused by the operation or use of a motor vehicle.
See, e.g., Dalon v. City of DeSoto,
. The intent of single legislator, even a statute's principal author, is not controlling legislative history but may be persuasive authority.
General Chemical Corp. v. De La Lastra,
. The Texas Department of Highways & Public Transportation’s Procedure for Establishing Speed Zones was the third of three documents of which the Bellnoas asked the trial court to take judicial notice.
