One of the first skills a new driver
learns is to recognize and identify the various street signs that they interact
with daily. The City of Carrollton maintains thousands of traffic signs with
various material types and purposes. The Texas Manual of Uniform Traffic
Control Devices (TxMUTCD) serves as a guideline for the installation of
roadway signs. Several different categories of traffic signs exist. To
request information about a particular sign or to discuss the
requirements for installation of a sign, please call us at
972-466-3050
or contact us. The following is a brief summary
of the various types of signs:
|
- Regulatory - black on white or white on
red
- Warning - black
on yellow
- Construction - black on orange
- Guide - white
on green, white on blue or white on brown
- School - black on fluorescent yellow-green
|
| |
|
| Regulatory signs include stop signs, speed limit signs, and
parking signs. These signs are mandated by law to be obeyed. Disobedience of
these traffic signs is punishable by a fine. When these signs are
posted within a construction work zone, traffic fines may be doubled.
Regulatory signs are installed based on TxMUTCD guidelines and engineering
studies. |
| |
|
|
Warning signs are installed to warn
drivers of a possible unexpected change in driving conditions. Curve
ahead, merge signage, divided highway, and dead end signs are examples
of warning signs. Warning signs are installed based on TxMUTCD guidelines
and engineering studies.
|

|
| Construction
signs are encountered on a regular basis.
These signs can be installed for a short duration such as the repair of a
pothole or can be installed for a long duration (i.e. the construction of the
President George Bush Turnpike). Contractors who operate within the city of
Carrollton are obligated to provide a traffic control plan to the City of
Carrollton. This control plan indicates how they intend to handle traffic
during their operation and which construction signs they intend to use. The
TxMUTCD Part VI
details the various components of traffic control plans and the
available signs. . |

|
| Guide
signs can
be blue and white, brown and white, or green and white. The color of the sign
indicates to the driver the content and purpose of the sign.Guide signs are
installed after careful consideration. It would be very easy to saturate
drivers with too many signs. The TxMUTCD and engineering studies are used to
determine appropriate guide sign placement. |
- White on green guide signs are directional.
They provide distances to a location (i.e. Dallas 24 miles), street
identification (i.e. Josey Lane and Jackson Road) or exit guidance (i.e. Sandy
Lake Drive Next Exit).
- White on brown guide signs are used to
identify recreational and cultural interest sites. For example, the signs can
indicate direction to the Perry Homestead or Swimming
facilities.
- White on blue guide signs are used to tell the driver of general motorist services.
These signs indicate the location of food and lodging, rest areas, or hospital
care.

| School signs are installed adjacent to educational
facilities. These facilities might be an elementary, junior high, or high
school. They could also be installed adjacent to a university or an alternative
education center. In the past few years, the City of Carrollton has installed
the brighter fluorescent yellow-green signage. This special material has a very
high reflectively and has been shown to increase driver awareness -
particularly around schools. |
