Comment Update: Based upon the comment, it appears you are asking after the fact, not in anticipation of having enough protection. If this is correct then you do have options. Your best option is to file the claim with your company and if you have appropriate coverage, then your company will pay the claim. That is the reason you have insurance in the first place. IF you don't have coverage for the claim then you have to take legal action against the at-fault uninsured driver.
