Regulatory Speed Signs (R2 Series)

Signs for regulatory speed zones shall be from the R2 series as shown in the
Texas Manual on Uniform Traffic Control Devices
(
TMUTCD
) and shall be of the appropriate design — including size, text, and color. At the end of speed zones on conventional highways where the maximum legal rural speeds are permissible, an R2-1 SPEED LIMIT XX sign (or larger size sign showing those limits) should be erected in accordance with the TMUTCD. At the end of speed zones on freeways where the maximum legal rural speeds are permissible, The R2-1 SPEED LIMIT XX sign showing those limits shall be erected.
Figure 2.2 illustrates the typical location and frequency of signs for regulatory speed zones. Distances shown between speed limit signs are examples and may be greater, depending on the results of speed checks. Posted regulatory speed limits will be based on the 85th percentile, as described in
Chapter 3, Determining the 85th Percentile Speed
