Traffic signals should be maintained in their originally built condition. Traffic signal malfunctions should be repaired as soon as possible. Only trained maintenance personnel should be allowed to perform traffic signal maintenance.

All department personnel should immediately report any malfunctioning traffic signal. Notify law enforcement if traffic control is needed until the signal is repaired.

All maintenance work performed at signal locations should comply with the requirements of the

Texas Manual on Uniform Traffic Control Devices

(

TMUTCD

) and the

Traffic Engineering Standard Sheets

.

Records should be kept on all traffic signal maintenance or repair. These records should include the time and date of the maintenance at each traffic signal location.
