Lying about an accident?

So I had 50% fault in a recent accident and went with my own insurance. The accident wasn't reported to DMV and no police report. Come September, my premium will definitely go up. I have had a spotless driving record in 7 years except this accident. What if I shop for insurance and don't tell them about this accident?

 

Yes, both insurance companies are aware of everything

 

Also, I have developed this pain in my right shoulder after the accident. I have not visited a doctor yet. I am toughing it out. I should be fine, this pain should go away.

 

It is not too bad. No need for Alieve.

 

I could not trust the other driver and his intentions. I reported everything to make sure I avoid any future problems. My premium will probably increase by $75-$100/month. I guess I will have to accept that as a fact of life.

 

Meanwhile the other driver is so care free, their adjuster haven't been able to even get them on the phone yet, forget about them reporting the accident lol. Infact, their car is not even on the policy that they shared with me. So, I was left with no choice but to pay my deductible and get my car fixed.
