Safety first
If anyone is hurt, call 911. If the cars can be moved and it's safe, get out of traffic.

Report it to the right agency
On Altadena's local streets that's California Highway Patrol (CHP); on the I-210, the CHP.

Exchange information and take photos
Names, license, plate, insurer and policy number — then photos of both cars, the scene and the damage.
- 04

California requires it when anyone is injured or property damage exceeds $1,000.

Choose your shop
Your insurer can't require a particular body shop (Cal. Ins. Code § 758.5). Tell them your car is going to Top Tier.
Foothill heat & fire season
What San Gabriel Valley roads do to cars.
Foothill heat and UV that oxidize clearcoat and fade older single-stage paint.
Rear-end and merge collisions on the I-10 and I-210.
Parking-lot damage around dense retail and restaurant corridors.
The I-210 Foothill Freeway, I-10, CA-60 and I-605 carry the valley's commuters, and the I-605 interchanges with the I-10 and I-210 back up daily. Colorado, Huntington, Valley and Garvey absorb the overflow.
Foothill communities get valley heat plus canyon hazards and, in fire season, ash fall. Ash left on wet paint can etch the finish, so rinse it off gently with plenty of water rather than wiping it dry.
