Katy-area drivers who have enjoyed a 36-minute cruise to downtown Houston this summer are about to lose that luxury. Once schools are fully in session by September, that same commute will stretch to 57 minutes, according to Houston TranStar data reported by KHOU.

That's a 21-minute increase, and it starts building the week of Aug. 11.

Katy ISD's first day is Wednesday, Aug. 12. Lamar CISD returns a day earlier, on Tuesday, Aug. 11. Both districts will put thousands of buses, walkers and young cyclists back on roads that have been relatively quiet since June.

What TranStar is telling drivers

Houston TranStar spokesperson Angelique Meyers told KHOU on Thursday, Aug. 6, that the biggest mistake commuters make at back-to-school time is failing to plan ahead.

"Come September when school's in session, that jumps to 57 minutes," Meyers said of the Katy-to-downtown corridor.

TranStar recommends drivers check the agency's homepage before leaving each morning. The site lets users filter incidents by highway to see real-time conditions. The agency also urges commuters to leave earlier and slow down in school zones.

School zone rules carry real fines

Texas law doubles speeding fines in active school zones. With most zones posted at 20 mph, a violation plus court costs can run $250 to more than $500. Handheld phone use is also banned in active school zones, carrying an additional $100 to $200 penalty.

Drivers must stop for school buses displaying alternating flashing red lights while loading or unloading students.

Local agencies already gearing up

Fulshear Police issued a back-to-school traffic advisory calling the start of a new school year one of the busiest traffic periods. The Fort Bend County Precinct 1 Constable's Office, which serves Katy and Fulshear under Constable Chad Norvell, has previously deployed deputies to monitor school crosswalks in Katy ISD after receiving community complaints.

TxDOT brought its "Be Safe. Drive Smart." speeding awareness exhibit to the Buc-ee's at 27700 Katy Freeway on July 24. The agency reported that speeding contributed to more than 150,000 crashes statewide in 2025, killing 1,247 people and seriously injuring 5,652 others.

How to prepare

Eight Houston-area districts had already started the 2026-27 school year as of Thursday, Aug. 6, with dozens more returning in the coming weeks. TranStar's advice: check traffic conditions at the Houston TranStar website before leaving, build extra time into morning routines and watch for flashing school zone lights that have been dark all summer.

Residents who see dangerous driving near schools can report concerns to Katy Police, Fulshear Police or the Fort Bend County Precinct 1 Constable's Office.
