Distraction can help explain how a crash happened, but an injury claim still needs proof linking conduct to the collision and harm.

## California rules on handheld phone use

Vehicle Code section 23123.5 addresses specified use of handheld wireless devices. An allegation that someone looked at a phone is not the same as proof of a violation. Other kinds of distraction can also matter under ordinary care rules even when a particular phone statute does not fit.

## Evidence of distraction before a crash

Describe what you actually saw, such as a driver holding a device or looking down. Keep lawful video and witness information. Do not try to access another person’s phone, cloud account, or messages. Counsel can consider proper preservation requests and legal discovery.

### Mitchell v. Gonzales

(1991) 54 Cal.3d 1041, pp. 1049–1053. The court favored a substantial-factor instruction for cause in fact over a confusing older instruction.

Limits: Proof of a careless act alone is not enough. The claimed harm must still be linked to that act.
