Save the evidence immediately, because some of the most useful proof can disappear within days.

Start with the crash scene. Take photos and video of all vehicle damage, license plates, debris, skid marks or lack of skid marks, traffic lights/signs, road conditions, and any visible injuries. In Michigan winter crashes, also photograph snow, ice, slush, salt coverage, and visibility before conditions change.

Get the other driver's name, phone number, address, plate number, insurer, and policy number. If anyone heard or saw the driver using a phone, get that witness's full name, phone number, and a short recorded statement on your phone if they agree.

Ask officers how to get the Michigan Traffic Crash Report (UD-10). If police responded, that report often notes driver statements, witnesses, weather, and whether distracted driving was suspected. For many agencies, you can request it through the local department or the Michigan State Police if they investigated.

Preserve your own electronic evidence too:

• Dashcam footage
• Cell phone photos/videos with timestamps
• Call logs and texts showing what happened before and after the crash
• GPS/app ride history
• Medical records and discharge papers
• Repair estimates and towing/storage receipts

If nearby businesses, homes, or public buildings may have cameras, ask for that footage the same day. Many systems overwrite video in 24 to 72 hours. The same urgency applies to your own dashcam; make a backup right away.

You usually cannot get the other driver's phone records on your own, but you should write down exactly why you suspect texting: head down, phone in hand, delayed braking, drifting, or an admission at the scene. That helps preserve the issue before memories change.

Also notify your auto insurer promptly. In Michigan, No-Fault/PIP claims and vehicle damage issues often start moving before the distracted-driving evidence is fully collected.
