The cost to replace is $10 and you will need (2) forms of ID which would include proof of residence.
The fee will be waived for a stolen license or identification card if a police report has been filed. Please have a copy of the report with you when applying for the replacement.
So for free would have to file a police report. I can't find anything about being free if on food stamps. .
Lost or stolen licenses can be replaced. There may be a fee. Food stamps will be a moot point. It will not be free despite being on food stamps.
What does you getting food stamps have to do with your license?
DMV doesn't take stamps as payment.
