Effective immediately, owners of hybrid and other alternative fuel vehicles will not pay an excise tax and will have a reduced registration rate, while excise tax rates for heavy passenger vehicles (over 5,000 pounds) will increase to 8% (from 7%). (Normal Excise Tax was 6% of Purchase Price. Now it's 0 for Hybrids. Hybrid Registration is now $35/Year) http://dmv.washingtondc.gov/about/041505.shtm
