Multi-Vehicle Collisions in California
Multi-vehicle crashes, like the one that occurred on the US 101 to I-380 connector in San Bruno, often result in lane closures, extended traffic delays, and a higher risk of injuries due to the chain-reaction nature of the impacts. This interchange is a busy connection point between San Mateo County’s main freeway corridors, with high traffic volumes at nearly all hours of the day. The combination of merging traffic, varying speeds, and driver inattention can quickly lead to serious collisions.
Tuesday night’s crash serves as a reminder for motorists to maintain safe following distances and to remain alert during lane changes or while navigating freeway connectors. Reduced speeds and careful observation of surrounding traffic can help prevent these incidents, particularly in high-congestion areas.
