A fully loaded big rig jackknifed on Interstate 35 northbound near the Walzem Road exit in San Antonio on June 1, 2026, during a period of heavy rainfall. The truck's trailer swung across all three northbound lanes, blocking traffic completely.
The driver was not seriously injured but was taken to a local hospital for evaluation. No other vehicles were directly struck, though several motorists reported near-misses as they attempted to brake on the wet pavement.
Traffic backed up approximately eight miles before TxDOT crews and San Antonio Police Department officers could clear the scene. The cleanup took approximately four hours.
Weather-related truck accidents raise important questions about driver training and company policies. Trucking companies are required to train drivers on adverse weather operation. If a company's negligence contributed to this crash, victims may have a claim.
