Whether it is Porsche or not, in general, the renter is responsible for the car's safety and who drives it. In Dubai, it is prohibited to drive a rented car without a clear mention to the drivers of this car in the written contract. At Grand Royal, we offer a Free Driver in addition to any hired car in Dubai if you need to add a driver with you. Whereas some other renting companies add charges for adding a driver to the vehicle renting contract.
