Car damage property and billboard sign that I own how to proceed?

[Shin Bo]

So this morning I received a call that a car and hit a pole damaged my billboard/signage as a result. Thankfully no one was seriously hurt, but I'm curious whats the best way to proceed? The police and the energy company have already been out to try and fix the power lines and stuff. I tried calling our insurance agent but since its the weekend they haven't responded. Is it necessary to have an adjuster? The police have already written the report. I'm just looking for advice to best protect my assets and filing the claim afterwards. Hopefully the driver has enough coverage.
