SAN MATEO, San Joaquin County, Calif., Oct. 29, 2026 — A two-vehicle crash blocked lanes on northbound Route 99 at Peltier Road early Tuesday morning, October 27, according to the California Highway Patrol. At least one person was taken to a hospital with injuries described as minor.
The CHP said the crash involved a gray Honda Accord and a white Ford pickup truck. Initial reports to dispatchers described a car stopped on the right shoulder with hazard lights on and debris scattered across two lanes, prompting a response from the California Highway Patrol and Stockton Fire.
One party was transported from the scene, the CHP reported, though further details on the extent of injuries were not released. Two tow trucks were requested to clear the vehicles, and crews later found damage to roadside guardrail posts and fencing near the shoulder and frontage road area, according to the incident log.
The roadway reopened after cleanup, though traffic backed up in the area while crews worked. The CHP has not released a cause for the crash, and the incident remains under investigation.
We hope everyone who was hurt makes a full and speedy recovery.

What to Do After a Car Accident in Lodi, CA
If you're involved in a crash on a highway like Route 99, move to the shoulder if possible and turn on hazard lights to warn oncoming traffic. Check yourself and any passengers for injuries, and call 911 even if injuries seem minor, since some symptoms take hours to appear.
