<p>They’d probably just take a police report and see if anyone else makes a report in turn. I’d definitely do it soon before someone files a hit and run report. You have no idea who you hit, they may be from out of town, drug dealers, the mayor, it may never even be reported. You can only do what you need to do to clear your conscience.</p>

<p>Cops like truthfulness but they also have to operate within the law. Do you have access to a lawyer that you could run it by before you proceed? Not saying it will come to that but just to make yourself feel better. Your are overwrought with guilt and may need a more objective opinion about what exactly you should do/say. Attorneys are good for that.</p>
