Hit by uninsured motorist... no coverage on my car but another in our policy?

I was rear-ended by an uninsured driver and she admitted to the police she was at fault and a report was filed. I do not have uninsured motorist coverage on my car but my husband has it on his car and they are on the same policy. Is this considered stacking and does that coverage extend to my vehicle or does it specifically have to be on my car. We live in Colorado.
