MODESTO, Calif. — Multiple traffic collisions were reported in the Modesto area today, September 12, 2026, as emergency responders were called to incidents on Highway 99 and McHenry Avenue.
The crashes caused potential traffic disruptions for motorists traveling through the area, with authorities responding to the reported collisions and working to assess the circumstances.
At the latest available update, authorities had not confirmed a fatality connected to today’s reported Modesto crashes. Information about possible injuries and the circumstances of the collisions remained limited.
Modesto Accident Today on Highway 99
One of the latest reported collisions occurred on northbound State Route 99 near the West Briggsmore Avenue off-ramp.
The California Highway Patrol reported the collision at approximately 9 p.m. Emergency medical personnel were also reported to be responding to the area.
The available preliminary information did not establish how many vehicles were involved or whether anyone suffered serious injuries.
Motorists traveling northbound through the area may experience slowing or delays as emergency crews respond and authorities assess the crash.
Crash Near West Briggsmore Avenue
The Highway 99 collision occurred near the West Briggsmore Avenue exit, an area that can experience significant traffic during busy travel periods.
When a crash occurs on a freeway, even a collision involving relatively few vehicles can create congestion as approaching motorists slow down or lanes become temporarily restricted.
Drivers approaching the scene should follow directions from CHP officers and other emergency personnel.
Motorists should also avoid stopping near the crash to observe or photograph the incident, as doing so can interfere with emergency operations and create additional hazards.
McHenry Avenue Accident Reported
Another collision was reported later on McHenry Avenue near Ladd Road.
The incident was recorded by authorities at approximately 10:45 p.m.
As with the Highway 99 crash, the initial information did not provide a complete account of the circumstances, including the number of vehicles involved or the extent of any injuries.
Officials may release additional information as the response continues and investigators establish what happened.
Have Any Injuries Been Confirmed?
At the latest available stage of the reports, there was no confirmed information establishing a fatality in today’s reported Modesto collisions.
Emergency medical personnel were dispatched to at least one of the reported crash locations, but the available preliminary information did not provide a confirmed injury count.
Early traffic reports can contain limited information because emergency responders and investigators may still be assessing the scene.
Any claims concerning serious injuries or fatalities should therefore be treated cautiously until confirmed by authorities.
What Caused the Modesto Crashes?
The causes of today’s reported collisions have not been established in the available information.
Investigators may examine several factors when determining how a traffic accident occurred, including vehicle movements, roadway conditions, traffic patterns, visibility, weather, mechanical issues and possible driver-related circumstances.
No particular cause should be treated as confirmed unless it is released by CHP or another authoritative agency.
The fact that emergency crews responded does not, by itself, indicate the severity or cause of a collision.
Earlier Fatal Modesto Pedestrian Crash
Today’s reported incidents are separate from an earlier fatal pedestrian collision on Highway 99.
On September 2, 2026, a pedestrian was struck and killed while attempting to cross northbound Highway 99 south of Carpenter Road, according to previously reported information.
The driver involved in that crash was not injured, and authorities did not identify impairment as a contributing factor in the preliminary information available at the time.
That fatal collision should not be confused with the crashes reported in Modesto today.
Highway 99 Traffic Impact
Highway 99 is an important north-south route through the Central Valley, meaning collisions can quickly affect traffic in and around Modesto.
A crash near an off-ramp can also create congestion as drivers enter or leave the freeway and traffic backs up around the affected interchange.
Motorists traveling through Modesto should allow additional time if they encounter emergency activity and remain alert for sudden lane changes or stopped traffic.
Drivers should never attempt to drive through an active crash scene unless directed to do so by authorities.
Investigation Continues
Authorities are expected to continue reviewing the circumstances surrounding the reported collisions.
Investigations can involve examining vehicles, roadway conditions, witness information and other available evidence.
Additional information may become available if officials determine that injuries occurred, identify additional vehicles involved or establish a cause for either collision.
Until then, motorists and members of the public should rely on verified information from law enforcement and emergency authorities.
