Unfortunately, deductible cannot be waived. When recovering the cost of your deductible especially if the other driver is uninsured, it is completely up to you. It is highly advisable that you talk to your respective insurance company and see whether you have other options. Chances are you will have to pay for a deductible in order to start the repair process. If you are not in a position to work it out with your relevant insurance, you might consider taking the uninsured driver to small claims courts. Another option is maybe contacting an attorney to talk the details of what you can be able to do.
