The crash happened at the Willow Road on-ramp leading to southbound US-101. A gray Dodge Charger sustained major front-end damage and a blue Tesla Model Y sustained major rear-end damage, both coming to rest on the right shoulder of the ramp. The collision was initially logged as a crash with no injuries, but the CHP updated the call to indicate an ambulance was being sent, and records show San Mateo County fire personnel were notified to respond for an injury.
The on-ramp was blocked in all lanes for a time while crews worked the scene, the CHP log indicates. Tow trucks were later called to remove both vehicles from the roadway.
The incident remains under review. We hope everyone involved comes through this safely.

Frequently Asked Questions
What typically causes crashes on freeway on-ramps?
On-ramp collisions commonly happen when a merging vehicle misjudges the speed of freeway traffic or when vehicles ahead slow or stop unexpectedly, leading to rear-end impacts.
Does speed make a difference in how serious a crash is?
Yes. Higher speeds give drivers less time to react and increase the force of impact, which usually means more vehicle damage and a greater chance of injury.
Why is distracted driving considered so risky?
Taking attention off the road for even a few seconds, such as to check a phone, can prevent a driver from noticing slowing traffic or a merging vehicle in time to avoid a crash.
How do conditions like rain or fog affect crash risk?
Wet or foggy conditions reduce tire traction and visibility, which can lengthen stopping distances and make it harder for drivers to react to sudden changes in traffic.
