Arrow Signs (Texas MUTCD
2D.26 and 2D.28
)

Purpose:
Arrow signs indicate the direction of turn necessary to travel on the indicated highway in the indicated cardinal direction. An Arrow sign is mounted below the route sign(s) to which it applies. There are two types of arrow signs: Advance Turn Arrow auxiliary sign and Directional Arrow auxiliary sign.
  • Advance Turn Arrow Auxiliary Signs (Texas MUTCD
    2D.26
    )
    • Advance Turn Arrow
      auxiliary
       signs are used in the Advanced Route Turn Assembly (see page 3-29) to indicate that the route the driver is currently on turns at the highway intersection. This typically occurs where two concurrent (overlapping) highways split, and the driver is required to turn to stay on one of the highways. Advance Turn Arrow auxiliary signs are used only in an Advance Route Turn Assembly (see page 3-29). Examples of Advance Turn Arrow
      auxiliary
       signs are shown in Figure 3-9.
    • The Texas MUTCD requires (a shall condition) the Advanced Route Turn Assembly to be used when a turn must be made to remain on the indicated highway. The Advance
      Route
       Turn Assembly is described in more detail on page 3-29.
  • Directional Arrow Auxiliary Signs (Texas MUTCD
    2D.28
    )
    • Directional Arrow auxiliary signs are used to indicate the direction that a driver must follow to travel on the indicated route. Directional Arrow auxiliary signs are typically used only in Directional Assemblies, although similar type arrows are also used as a component in Destination and Combination stand-alone signs. The sign can display either a single- or double-headed arrow, as shown in Figure 3-10. The use of Directional Arrow auxiliary signs in a Directional Assembly is described on page 3-31.
