**HOUSTON** — The Houston metropolitan area recorded 1,045 traffic incidents on Sunday, March 15, 2026, marking an exceptionally busy day on regional roadways. According to traffic data, the day saw 528 major crashes and 517 minor incidents spread across eight counties, with the overwhelming majority occurring in Harris County.
Harris County dominated the incident count with 965 reported cases, while Fort Bend County followed with 61 incidents. Montgomery County reported 9 incidents, Galveston County 5, and Milam, Liberty, Burleson, and Waller counties each recorded fewer than two incidents. The high concentration of incidents in Harris County reflects the density of traffic in the greater Houston area, particularly during evening hours when most of the recorded incidents occurred.
Late evening hours proved especially problematic, with multiple major crashes reported between 10 p.m. and midnight. Notable incidents included major non-fatal crashes on Holcombe Boulevard, multiple accidents on Richmond Avenue, and significant incidents on North Houston Rosslyn Road, SH-99 at Lanier/Grand Parkway, and the North Freeway near the Gulf Bank exit ramp. Westheimer Road also experienced multiple collision reports throughout the evening hours.
Traffic safety officials urge Houston-area drivers to exercise heightened caution during peak evening hours and to remain vigilant for sudden slowdowns and accident scenes. Motorists are advised to maintain safe following distances, avoid distracted driving, and consider using real-time traffic applications to route around congested areas. Those involved in minor accidents are encouraged to move vehicles to safe locations when possible to prevent additional incidents.
