UAE Dirving License accept to use in KSA for any car?

Dear

I have UAE driving license, and often visit to Riyadh for working.

First, I note a UAE driving license be accept to rent a car in Riyadh.
Second, If I drive a personal car owned by another person or drive a company car from my partner,
Does my UAE license accepted to drive a car legally?
I have ID in UAE, but I am only visitor status in KSA (no having Iqama in KSA)
Someone says my UAE license cover any car, in the other someone says can drive only rental car.

Pls advise who know it exaclty.

You can only use UAE license to drive a rental car IF you are on a visit visa in Saudi.

You are not allowed to drive a personal car under someone else's name with the UAE license. To be honest, no one checks but if there is an accident then there will be problems especially with insurance.

Thank you so much for your reply.
