When to Replace Signs
Time alone does not determine when to replace a sign. Signs
facing the sun require replacement more frequently than those that
do not. Vandalism is a major cause of sign replacement.
Sign replacement is required when either of the following
occurs:
- the sign or its support suffers major damage
- the sign sheeting is below minimum retroreflectivity levels as shown on of theTexas Manual on Uniform Traffic Control Devices(TMUTCD).
Maintenance personnel should use good judgment in determining
whether to replace a sign or make repairs in the field. In borderline
cases, the decision should be made in favor of replacement.
