Speed limits on the UAE roads are set as per technical reports on traffic flow submitted by engineers in each emirate. In all emirates except Abu Dhabi, a speed buffer allows motorists to travel 20kmph more than the stipulated speed limit. Abu Dhabi did away with the buffer system in 2018.
The Dubai Police have a section on their website that details the speed limits on various roads. As per the latest update made today, January 13, the limits range from 60 to 120kmph. On the Mohamed Bin Zayed and Emirates roads, the speed limit remains 110kmph, while on several internal roads, it is set at 70kmph.
