There are a couple ways to look at things. You are able to file a claim
with your insurance company for the damage to your vehicle, regardless if you filed a police report or not. The statute of limitations
for property damage in Mississippi
is 3 years. However, the other side of this is the damage you did to the pole. If there were cameras in the area and they reviewed the damaged, you could be charged with a hit and run. Which tend to be the most expensive violations you can be charged with. I would survey the damage you caused and weigh your options.
