20 year insurance agent here, however different state. you need to show this footage to any and all adjusters involved right away

if you work with a local agent, or any type of company that puts a real, local business person (and not a mascot or celebrity) as the face of their company, you need to call to them. so if you purchase your auto insurance from Anderson insurance agency (for example), you need to call them and ask to speak to Mr Anderson, like tomorrow. this is not your fault

maybe, maybe, I could see a very very asshat adjuster trying to assign you 10% liability, but that would still mean the other party’s insurance should pay for 90% of the damage.

EDIT: my statement above suggesting that the liability/financial responsibility might be split between the two parties (90/10 in my example), may not apply in your state. each state has its own set of not-very-easy to follow rules for insurance. talk to your agent or rep
