Transfer of Ownership of car from spouse of a deceased person

I am not sure of the exact procedure and you would need to approach the traffic directorate for that.

What I do know is that in the GCC, inheritance laws govern the transfer of assets on death.  And it varies for muslim and non-muslim expats.   Non-muslim expats need to have a will and if they do, that is upheld by the Bahrain courts.  If the expat is Muslim or there is no will, you need to approach the courts for a judgement.

So basically, to transfer assets like property (and even cars), you would need a death certificate and a court decree approving inheritance of all assets in the name of the wife (either through ratification of existing will for non muslims or a stand alone judgement for muslims).  This would then allow for the transfer to take place.
