Texas Department of Public Safety

The Texas Department of Public Safety (otherwise known as DPS), is a state law enforcement agency responsible for "enforcing laws, administering regulatory programs, managing records, educating the public, and managing emergencies, both directly and through interaction with other agencies."

Texas DPS is divided into 6 Regions, with multiple Communications Centers for each region. The regional headquarters are in:

  • Dallas (Reg. 1)
  • Houston (Reg. 2)
  • McAllen (Reg. 3)
  • El Paso (Reg. 4)
  • Lubbock (Reg. 5)
  • San Antonio (Reg. 6)
  • Austin (State Headquarters)

According to a press release dated 10/21/2010, the DPS will close communications centers in Sherman, Texas City, Beaumont, Ozona, San Angelo, Childress and Harlingen.

As of 1 December 2009, DPS has reorganized their radio unit numbers. See the Region Map below to see if your closest Communication Centers might be handling different Regions. Expect a description of the reorganization soon. For a discussion of this unit re-numbering see here.

Within the past few years DPS has migrated all of its radio systems to a conventional P25 digital protocol, which is capable of linking any Comm Center in the state to any other by VoIP, essentially giving any trooper the ability to talk to any other, statewide. DPS also has networked 5 facilities into the Harris County Regional Radio System (Texas SCIP p. 28) and two facilities into the City of Austin/Travis County Regional Radio System (Texas SCIP p. 28).

The Texas SCIP has stated, on page 28, that DPS "will migrate toward a statewide hybrid trunked radio system utilizing 700MHz where feasible," accessible by all state agencies. The THP Strategic Outlook from the DPS website, also shows that this is the current plan, on page 44.

 DPS uses linked repeaters and base stations at many Comm Centers. When dispatchers 
transmit, they may be broadcasting over many linked sites at once, while the
trooper is only being broadcasted on their local site. This limits a receiver to hear
only the dispatch side of conversations at times. DPS also uses half-duplex on their
base stations at times. In this case, the trooper will broadcast on a "Mobile to
Base" frequency, while dispatch listens on this frequency. To respond dispatch
transmits on a "Base to Mobile" frequency, while the trooper listens on that same
frequency. This may also cause a receiver to only hear the dispatch side, since
usually the dispatcher is broadcasting from a tall tower, relative to the trooper
broadcasting from ground level. Reports have indicated that in the future more
Base outputs will be rebroadcasting the "Mobile to Base" side of the conversation
which has been noted on San Antonio's Base B1 recently. See below for a "working"
list of linked sites.


The Department of Public Safety is comprised of 8 Divisions:

  • Administration
  • Criminal Law Enforcement
  • Director's Staff
  • Texas Division of Emergency Management
  • Driver License
  • Public Safety Commission
  • Texas Highway Patrol
    • Commercial Vehicle Enforcement
    • Communications

Texas Division of Emergency Management

The Division of Emergency Management is the statewide commssion responsible for disaster preparedness. They report directly to the Governor of the State of Texas. They are the state agency responsible for coordinating the Radio Amateur Civil Emergency Service (RACES) and homeland security preparedness drills.

The DEM has split the state into disaster districts and sub-districts. That map is available here.

Texas Highway Patrol

Otherwise known as "troopers" or "THP," the Highway Patrol is the most visible division of DPS, tasked with enforcing traffic laws on Texas highways.

Commercial Vehicle Enforcement (CVE)

The CVE Unit of THP is the enforcement unit of commercial vehicle traffic, ensuring all weight/size regulations are followed, ensuring compliance with the Motor Carrier Safety Act. They also ensure hazardous material placarding regulations are followed, as well as commercial vehicle registration enforcement. There are 41 CVE Offices throughout the state, including 2 at El Paso's Bridge of the America's POE and the Ysleta POE.


There are 32 Communications facilities throughout the state as well as one mobile unit, the Communications Emergency Operations Team, which is supported by Command One, a 30 ft. mobile communications trailer. See the linked press release above, for a list of Comm Centers that will be closing, reducing the number down to 22.

Texas Rangers

Texas Ranger Crest

The Rangers are famed as the oldest law enforcement agency in the country with statewide jurisdiction. Currently, there are 144 commissioned officers, by state congressional act, and they are split into 7 troops "A-G."

Recently there have been signs that the Rangers are reorganizing and downsizing to 6 troops.
