Safety lighting is used at specific spot locations to enhance safety of the facility. TxDOT bears the cost of installation, operation, and maintenance of safety lighting at interchanges, highway intersections, and points of night time hazard in both urban and rural areas, as traffic needs dictate.

If the safety lighting is within a municipality, TxDOT must enter into an agreement with the city. The type of agreement depends on whether TxDOT will maintain the system directly or contract with the city for maintenance.
