So today I was rear-ended in the stop-and-go morning commute. Guy didn't react quickly enough. Even though I distinctively felt the impact, I haven't noticed any damage on the first inspection Given my car wasn't that clean, so I have to wash it and look at bumper more closely.
Regardless I have the guy's insurance information.
Any experience in this type of situation? Any specific areas I should at as well?

I recently was rear ended, pretty hard by a Chevy Blazer and when looking under the car and around the bumper, with the exception of the plastic being slighted dented, the bumper otherwise was perfect. I also checked the bumper frame and support brackets and all was well. Honda did a great job building the back of these cars!
