Distracted driving is the hardest crash cause to prove and the easiest to deny. Nobody admits to it at the scene, and unlike impairment there is no roadside test. What there is instead is data — carrier records, handset forensics, vehicle telematics — and every category of it sits on a retention schedule. The cases that succeed are the ones where somebody demanded preservation in the first weeks.
There is no breathalyzer for attention. Proof is assembled from sources that each expire on their own schedule — carrier logs, handset contents, infotainment memory, event data recorders, and third-party video. None of it is preserved for you, and the defendant has no incentive to volunteer any of it. The work in these cases is front-loaded almost entirely into the first weeks.
Nearby surveillance and doorbell video typically overwrite within days to a few weeks. Vehicle infotainment memory is lost when the vehicle is repaired, sold or scrapped. Carrier detail records have finite retention that varies by provider. Handset data can be deleted by the user at any time. A written spoliation notice to the driver, their insurer and the tow yard, plus a preservation letter to the carrier, needs to go out in days rather than months.
Safety research divides driver distraction into three categories, and the distinction is useful because it explains why phone use is treated differently from other lapses.
Visual distraction takes the eyes off the road. Manual distraction takes the hands off the wheel. Cognitive distraction takes the mind off driving. Most activities involve one or two. Texting involves all three at once, which is why it is the behavior specifically legislated against and the one most strongly associated with crashes where the driver never braked.
Cognitive distraction is the reason hands-free is safer but not safe. A driver on a hands-free call keeps their eyes forward and their hands on the wheel while their attention is elsewhere — a phenomenon sometimes described as looking without seeing.
Subpoenaed from the provider, these show call and data activity with timestamps that can be aligned against the crash time. They establish that the device was active. They do not by themselves establish who was holding it, which is why they are one input rather than the whole case.
Where the phone itself is preserved, forensic examination can show app activity, message composition and screen state with far more precision than carrier billing records. This requires a court order in most circumstances and it requires that the device still exists in its post-crash condition.
This is frequently the strongest source and the most overlooked. Modern infotainment systems log paired device activity, text and call handling and interaction timestamps. The data lives in the vehicle, which means it is lost when the vehicle is repaired, sold or salvaged.
Speed, throttle, braking and steering in the seconds before impact. In a distraction case the significant finding is usually a negative one: no braking, no steering, no evasive action of any kind before a collision an attentive driver would have seen developing.
Other drivers frequently observe a head-down driver before a crash. Storefront cameras, doorbell cameras and dashcams capture the same thing. All of it overwrites on short cycles.
The pattern follows the road type. On the freeway corridors — 101, 280, 680, 880 — distraction produces rear-end collisions in slowing traffic and lane departures. On signalized arterials such as Stevens Creek Boulevard, Capitol Expressway, Monterey Road and Story Road, it produces red light entries and failures to yield on left turns. In residential and school zones it produces pedestrian and cyclist strikes, because the driver's eyes left the road for the two or three seconds in which someone entered the crosswalk.
Say what you observed, at the scene and in the report — whether the driver was looking down, whether the phone was in their hand, whether they braked at all. That observation, recorded contemporaneously, is what later justifies the discovery. Photograph the interior of the other vehicle if it is safe and lawful to do so, because a phone visible in a mount or in the driver's lap is evidence. Get witness contact information, since other drivers frequently saw the same thing. Note every camera in the vicinity. And move fast on preservation, because the entire evidentiary picture in a distraction case is built from sources that delete themselves on schedule.
