A significant traffic collision occurred today on State Route 78 East in San Marcos, CA, resulting in major traffic disruptions. The incident involved three vehicles, including a white Jeep that was reported to be on fire after being rear-ended by another vehicle. This collision led to the closure of the Nordahl off-ramp and the eastbound lanes of State Route 78, causing considerable traffic congestion in the area.

Emergency response teams from the California Highway Patrol quickly arrived at the scene to manage the situation and implement traffic control measures. The off-ramp was completely blocked, and the eastbound section of State Route 78 experienced significant delays as crews worked to clear the wreckage. Additionally, damaged signage along the off-ramp required immediate attention, with multiple signs needing replacement due to the collision.

Traffic was diverted as the California Highway Patrol issued a SigAlert, warning motorists of the ongoing backup and advising them to seek alternate routes. The road was eventually cleared, and normal traffic flow resumed later in the evening. Drivers are reminded to remain cautious while traveling in the area, especially during peak traffic hours.

This traffic incident highlights the importance of safe driving practices to prevent accidents and ensure the safety of all road users.
