TX 7904L2023A12 Motor Vehicle Tax 1979-04-16

Were Royal Traffic Director Message panels motor vehicles subject to Texas motor vehicle sales or use tax?

Short answer: No. Texas classified the manufacturer-built traffic message panels as movable specialized equipment because they performed a specialized function and were not designed to carry a divisible highway load. Motor vehicle sales and use tax did not apply, and required trailer tags did not change that result. Limited Sales, Excise and Use Tax might still apply.

Disclaimer: This is an April 16, 1979 equipment-classification response based partly on a product brochure that is not included in STAR's text. The definition and spelling of movable specialized equipment, vehicle classification, divisible-load analysis, trailer registration, and motor vehicle or limited sales and use tax treatment may have changed. The letter said limited tax might apply but did not decide it. STAR documents may no longer represent current policy even when not marked superseded. Taxpayer details are redacted.

About this page: The plain-English summary, reader guidance, and Q&A below were written by Ezel based on the official state tax ruling. The original ruling (linked on this page) is the authoritative source for any reliance.

Plain-English summary

Royal Traffic Director Message panels were movable specialized equipment, not motor vehicles, for the historical tax at issue.

The manufacturer built each unit entirely to perform a specialized function, and the panels were not designed to carry a divisible load on the highways. Motor vehicle sales and use tax therefore did not apply.

Required registration with trailer tags did not change the tax classification. The letter separately said Limited Sales, Excise and Use Tax might apply, without deciding that question.

What this means for you

The response classified the equipment by its design and function, not by the tag required for highway registration.

Common questions

Q: Did trailer tags make the panels taxable as motor vehicles?
A: No.

Q: Were the panels necessarily free of all Texas tax?
A: No. A different limited sales and use tax might have applied.

COMPTROLLER OF PUBLIC ACCOUNTS
STATE OF TEXAS
AUSTIN, 78774

BOB BULLOCK
Comptroller April 16, 1979

Dear ***:

As I informed you by telephone today, Royal Traffic Director Message
panels
are not motor vehicles and are not subject to Motor Vehicle Sales or Use
Tax.

These units are built entirely by the manufacturer, are designed and
constructed
to perform a specialized function, and are not designed to carry a
divisible
load upon the highways. Thus, they fall within the definition of moveable
specialized equipment, and may be taxable under Limited Sales, Excise and
Use
Tax.

I informed *** in the Lubbock County Tax Assessor-Collector's
Office
that these items were not subject to motor vehicle tax. Please note that
the
fact that the Texas Department of Highways and Public Transportation
requires
these units to be registered with trailer tags has no effect on the
taxability
of the units.

I am returning the product brochure you forwarded to *** in our
Lubbock Audit Office. Thank you for providing it for our use.

If we can be of any further assistance, please don't hesitate to contact
the Motor Vehicle Sales Tax Division or call 1-800-252-5555 toll free
from
anywhere in Texas.

Sincerely,
Victoria Reed Bailey
Motor Vehicle Sales Tax Division
