A major wreck was reported on northbound Loop 12 at Northwest Highway (Spur 348) in Dallas early Wednesday morning, September 2, 2026.
According to the traffic information provided, the collision was reported at approximately 6:45 a.m. The lane diagram shows the left travel lane closed, while the remaining northbound lanes, managed lane, and adjacent ramp areas remained open.

Left Lane Closed After Loop 12 Crash at Northwest Highway
The collision affected northbound traffic on Loop 12 near Northwest Highway during the Wednesday morning commute.
With the left lane blocked, motorists approaching the scene could encounter slowing traffic, emergency vehicles, sudden lane changes, and congestion as drivers moved into the remaining open lanes.
Because information about the wreck remains preliminary, it would be premature to attribute the collision to speeding, distracted driving, following too closely, an unsafe lane change, or another specific cause.
Evidence After a Major Loop 12 Car Wreck in Dallas
When someone is injured in a serious highway collision, evidence gathered shortly after the wreck may become important in determining how it occurred.
Potentially important evidence may include:
Dashcam footage
TxDOT traffic-camera footage
Nearby surveillance video
Photographs and videos from the crash scene
Witness statements
Dallas police crash reports
Vehicle event-data recorder information
Cell phone records when relevant
Vehicle damage and roadway debris
Tire marks and final vehicle positions

Crashes Near Major Dallas Interchanges Can Be Complicated
Loop 12 and Northwest Highway carry substantial commuter traffic through Dallas, and traffic patterns can change quickly near entrance ramps, exits, and connecting roadways.
When a wreck occurs near an interchange, investigators may need to determine whether a vehicle was changing lanes, entering or exiting the highway, responding to slowing traffic, or involved in a secondary collision.
The final position of the vehicles does not always establish how a crash began. Dashcam footage, electronic vehicle data, witness statements, physical damage, and roadway evidence may help reconstruct the sequence of events.
