You need some basic facts here:

1. What is the approximate dollar value of the damage to the Enterprise vehicle?
2. What is the approximate dollar value of the other vehicle?
3. Was anyone injured?
4. Was law enforcement notified or otherwise involved and have you been issued a summons, citation or other document (even possibly arrested)?

All of the above should calibrate your next steps. In particular, you should understand that while California cannot suspend a non-California drivers license, it most certainly can suspend your privilege to operate in California. Whether that matters to you depends on whether you may need to return to California and drive.

If you are not from the US, are unfamiliar with the system, and have the resources, this is where a lawyer can be of assistance. While you will have to pay for the lawyer's services, it is also easy to underestimate the risks here.
