PIP car tax 50% reduction

drongo22

Our car is in my wifes name and she uses it to go to work etc. I am a named driver. I get standard mobility. Can somebody confirm if I claim the 50% she cannot use it for her own use anymore? The DVLA states that the 100% discount for enhanced mobility the car can only be used by or for the claimant BUT does not state the same for the 50% reduction. I asked DVLA and they just quoted the 100% discount rule and ignored my question regarding the 50% rules (if any)!
