  Adopted national MUTCD
  Adopted national MUTCD with state supplement
  Adopted state-specific MUTCD

Road signs in Texas are regulated in the Texas Manual on Uniform Traffic Control Devices (TMUTCD), the standard for traffic signs, road surface markings, and traffic signals in the U.S. state of Texas. It is developed by the Texas Department of Transportation "in substantial conformance to" the national Manual on Uniform Traffic Control Devices (MUTCD) developed by the Federal Highway Administration (FHWA).

Adoption and compliance

[edit]

The 11th edition of the MUTCD was released on December 19, 2023 with an effective date of January 18, 2024.[1] Texas has two years from the effective date to adopt the new TMUTCD.[2]

The first edition of the Texas Manual on Uniform Traffic Control Devices was published in 1980.[3][4] This manual was most recently updated in 2014, after the revision 2 of the 2011 edition was released. Texas is among the ten states to have adopted its own MUTCD "in substantial conformance to" an edition of the national MUTCD, annotated throughout with state-specific modifications and clarifications.[5]

Regulatory signs

[edit]

Regulatory signs give instructions to motorists, pedestrians, and cyclists. Signs including Stop, Yield, No Turns, No Trucks, No Parking, No Stopping, Minimum Speed, Right Turn Only, Do Not Enter, Weight Limit, and Speed Limit are considered regulatory signs. Some have special shapes, such as the octagon for the Stop sign and the crossbuck for railroad crossings. These signs are in the R series of signs in the MUTCD and typically in the R series in most state supplements or state MUTCDs.

R1 series: Stop and yield

[edit]

The MUTCD's R1 series is for Stop and Yield. The 4-WAY and 3-WAY plaques (R1-3) were deprecated in the 2009 Edition of the MUTCD in favor of the ALL WAY plaque (R1-3P).

R2 series: Speed limit

[edit]

The MUTCD's R2 series is for speed limit signs. Some state supplements and state MUTCDs place various speed limit signs in other series. Speed limits in the United States are always in miles per hour.

R3 series: Lane usage and turns

[edit]

The MUTCD's R3 series of signs is for lane usage and turn signs.

R6 series: One way and divided highway

[edit]

R7 series: Parking

[edit]

The MUTCD allows for three types of parking signs: permissive, No Parking, and No Standing. However, in most states, there is an additional more restrictive one, No Stopping. These signs are found in the R7 series of signs in the MUTCD. Permissive parking signs allow for parking for either an unlimited or varied amount of time. They are often used in conjunction with parking meters and parking permits. They are specified by the MUTCD to be green on white. Local variations occur with additional information and slightly different designs. No Parking signs indicate that loading or unloading while temporarily stopped is permitted, but the driver must not leave the vicinity of the vehicle.[6] Some No Parking signs display time restrictions, while others are permanent restrictions. There are also temporary versions of the signs, often of similar design to the permanent ones. These signs are specified by the MUTCD to be red on white, although local variations occur. No Standing signs indicate that stopping temporarily to load or unload passengers is allowed, but vehicles cannot be stopped at the location for longer periods of time, even if the driver remains with the vehicle.[6] As with no parking signs, some restrictions displayed on the signs are permanent, and some are time-based.
