Tracy, CA (July 16, 2026) – A three-vehicle collision involving two Toyota Prius vehicles and a semi-truck was reported on Wednesday afternoon on westbound Interstate 205 just west of the W Grant Line Road on-ramp in Tracy.
According to dispatch information, the collision was reported at approximately 3:46 p.m. Initial reports indicated a silver semi-truck and two silver Toyota Prius vehicles were involved. One Prius came to rest in the center divider, while the semi-truck stopped on the right shoulder. A later update confirmed the second Prius was also in the center divider.
Witnesses advised that no vehicles had overturned, and a subsequent update indicated the collision was no longer blocking traffic lanes. A flatbed tow truck was requested to remove one of the damaged vehicles. The dispatch log did not confirm any injuries, and the identities of those involved have not been released.
Investigators continue working to determine what led to the collision. We hope everyone involved remained safe.
What Happens After a Freeway Collision Involving a Semi-Truck?
Collisions involving passenger vehicles and semi-trucks often require a detailed review because of the size and weight differences between the vehicles. Investigators typically examine vehicle damage, final resting positions, roadway evidence, and witness statements to determine the sequence of contact.
When a collision occurs on a busy freeway, disabled vehicles are often moved to the shoulder or the center divider as quickly as possible to reduce traffic congestion and improve safety. If a vehicle cannot be driven, a tow truck or flatbed is commonly used to remove it. Additional evidence gathered after the roadway is cleared may help explain how the collision unfolded.
