Hi, my name is Gardening01! Road tax exemption with a blue badge?

Being a blue badge holder doesn't exclude you from road tax (VED). You'll need to be claiming either Enhanced mobility PIP or high rate mobility DLA to be entitled to this. Please also be aware that if you do claim any of those benefits and you do claim the disabled road tax, the vehicle must only be used for your purposes. https://www.disabledmotoring.org/motoring/road-tax-exemption

If you're claiming standard mobility PIP then you can claim 50% reduction but again the vehicle can only be used for your purpose. https://www.disabledmotoring.org/motoring/road-tax-50-reduction
