This is an appeal from a summary judgment entered against appellant William Monroe Brookshire, plaintiff below, and for appellee, the Houston Independent School District. Appellant, an employee of appellee, sued for personal injuries caused by the allegedly negligent operation of a forklift at a warehouse owned and operated by appellee.
The sole question here is whether a forklift is a “motor vehicle” as that term is used in section 19A of the Texas Tort Claims Act, Tex.Rev.Civ.Stat.Ann. art. 6252-19 (Supp.1974).
Appellant alleges that he was injured as the result a fall, when a forklift, operated by a fellow employee, backed out from under a platform upon which appellant was standing and which was being held aloft by the forklift. Appellee moved for summary judgment, attaching the affidavit of Mr. Martin Robinson, appellee’s supervisor of warehouses. Mr. Robinson called the forklift a “narrow aisle stacker” and stated that it was used to move and stack merchandise. Several forklifts are in use at the warehouse, and all are powered by electric batteries. The forks move up and down, and pallets are placed on them. Mr. Robinson stated that the forklifts have never been operated on any public street or road nor were they intended for such use. They have no lights of any kind and require neither a license registration nor a *677 licensed driver. The trial judge held, as a matter of law, that such a forklift was not a “motor vehicle” within the meaning of section 19A of the Texas Tort Claims Act and that no genuine issue of material fact existed.
Section 19A of the Texas Tort Claims Act provides in full: “The provisions of this Act shall not apply to school districts or to junior college districts except as to motor vehicles.” The Act does not contain a definition of the term “motor vehicle.” The Legislature has defined the term in four other acts, and appellant places great reliance upon the differences in these definitions of the same term. The Regulation of Vehicles Act, Tex.Rev.Civ.Stat.Ann. art. 6675a-l(a) (1969), provides for the registration of vehicles and defines “vehicle” as follows:
‘Vehicle’ means every device in, or by which any person or property is or may be transported or drawn upon a public highway, except devices moved only by human power or used exclusively upon stationary rails or tracks.
“Motor vehicle” is then defined as a “self-propelled” vehicle. That- part of the above act which provides for the licensing of drivers contains precisely the same definition. Tex.Rev.Civ.Stat.Ann. art. 6687b sec. 1(a) (1969). The Uniform Act Regulating Traffic on Highways, Tex.Rev.Civ.Stat. Ann. art. 6701d sec. 2(a) (1969), defines a “vehicle” as follows:
Every device in, upon, or by which any person or property is or may be transported or drawn upon a highway, except devices moved by human power or used exclusively upon stationary rails or tracks.
“Motor vehicle” is then defined as every vehicle which is “self-propelled.” The Safety Responsibility Law, Tex.Rev.Civ. Stat.Ann. art. 6701h sec. 1(3) (Supp.1974) contains the following definition:
‘Motor Vehicle’ — Every self-propelled vehicle which is designed for use upon a highway, including trailers and semitrailers designed for use with such vehicles (except traction engines, road rollers and graders, tractor cranes, power shovels, well drillers and implements of husbandry) and every vehicle which is propelled by electric power obtained from overhead wires but not operated upon rails, [emphasis added]
The Motor Fuel Tax chapter of the Tax Code, Tex.Tax.-Gen.Ann. art. 9.01(2) (1969), V.A.T.S., provides:
‘Motor vehicle’ means every self-propelled vehicle designed for operation or required to be licensed for operation upon the public highway. Tractors, combines, and other vehicles not required to be so licensed shall be deemed to be motor vehicles to the extent they are operated upon the public highway with motor fuel on which the tax is required to be paid, [emphasis added]
The appellant acknowledges that a forklift is not a “motor vehicle” under the two definitions which employ the concept of being “designed” for use on the public roads. However, appellant argues that a forklift is a “motor vehicle” under the other two statutory definitions, because people and goods “may be transported” upon a highway by a forklift. He urges that any doubt should be resolved in his favor, because section 13 of the Texas Tort Claims Act calls for a liberal construction of the Act. It is also urged that, when conflicting statutory definitions are ignored, a forklift is a “motor vehicle” as that term is ordinarily and customarily defined.
None of the statutory definitions quoted above are controlling upon the question under consideration. When the Legislature defines a term in one statute and uses the same term in relation to the same subject matter in a later statute, it will be presumed that the latter use of the
*678
term is in the same sense as previously defined. Brown v. Darden,
Even though no statutory definition is controlling here, we believe that such a forklift is not a “motor vehicle” either under the statutory definitions which appellant believes militate in his favor or under the common, ordinary meaning of the term. The definition of “vehicle” in Articles 6675a and 6701d must logically be said to implicitly contain the concept that the device was
designed
to transport people or property upon the public highway. If a vehicle is simply every device which conceivably “may be” used to transport persons or property, in the sense of “might” be used, then a vast array of self-propelled devices having no relation to the public highways would be included in these statutes governing the public roads and highways. The commonly understood meaning of “may be” when used in a statute is “in the future,” unless a contrary intention appears from its use in the statute. Guerra de Chapa v. Allen,
One of the primary rules of statutory construction is that a term employed but not defined in a statute is to be given its ordinary and popular meaning. Numerous courts have given an ordinary and general definition to “motor vehicle” as used in insurance policies. In International Ins. Co. in N. Y. v. Hensley Steel Co., Inc.,
Appellant relies upon Davis v. National Casualty Co.,
An additional ground for our holding presents itself when section 3 of the Tort Claims Act, the basic liability provision, is compared to section 19A, the provision that school districts are liable for “motor vehicles.” Section 3 provides in pertinent part:
Each unit of government in the state shall be liable for money damages . . . or personal injuries . . . when proximately caused by the negligence or wrongful act or omission of any officer *679 or employee acting within the scope of his employment or office arising from the operation or use of a motor-driven vehicle and motor-driven equipment, other than motor-driven equipment used in connection with the operation of floodgates or water release equipment by river authorities, . . . under circumstances where such officer or employee would he personally liable to the claimant. . . . [emphasis added]
Section 19A states that school districts shall be liable for “motor vehicles,” but makes no mention of “motor driven equipment.” A forklift must logically be considered as either a “motor vehicle” or a piece of “motor driven equipment,” and we believe that it is a piece of equipment as that term is ordinarily and popularly defined. The maxim “expressio unius est ex-clusio alterius” is frequently applied in the construction of statutes, and it means simply that the “inclusion of the specific limitation excludes all others.” Harris County v. Crooker, 112 Tex. 4S0,
Section 13 of the Act provides that the “Act shall be liberally construed to achieve the purposes hereof,” but appellant places too great a reliance upon this injunction. The purpose of section 19A is obviously to create liability on the part of school districts solely for the operation of “motor vehicles.” Section 13 does not give carte blanche to the courts to extend the tort liability of school districts beyond the category expressly recognized, nor to extend that category by defining the terms used to describe it beyond their usual and ordinary meaning.
Affirmed.
