I got into a car accident and have damage to my car.

Call your own. They will contact the other company.

Most likely it isn't absolutely necessary to contact yours. Letting them know "just in case" might be a good idea though. You probably need to get estimates. Last time I dealt with this I didn't and they ended up sending someone out to estimate the damage ($1000 on a truck that cost $1400 and all I wanted was a new tail light.)

Someone has to report it whether that be you them or the police. I'd at least check.

call the block queen, she'll hook you up
