School Zone Flasher Testing Starts This Week

The Southlake Mobility Team will conduct school zone flasher testing in the following school zones from Monday, August 2 – Friday, August 6: Carroll ISD schools, Florence Elementary in Keller ISD and The Clariden School.

Testing will ensure that all the devices are visible and are operating in conjunction with school arrival and dismissal times.

The flashers are also programmed for early releases and to not flash on holidays.

Due to construction on N. White Chapel Boulevard, Carroll High School will only have one lane of traffic going southbound open as you approach Ascot Drive.

Please drive safely while zones undergo testing.
