Example Signing for Left Lane Restriction
If a left lane restriction is established, the NO TRUCKS LEFT LANE sign should be mounted as close to the left lane as possible as shown in Figure 5-8. The sign can be mounted on:
- an overhead sign bridge or cantilever
- a large roadside sign support
- a tower of an overhead sign bridge or cantilever.
