Fog blanketed parts of the UAE on Thursday morning, with Abu Dhabi appearing to be the most severely affected.
Abu Dhabi Police reduced speed limits to 80kph on routes across the capital amid worsening visibility on the roads.
The National Centre of Meteorology warned that the dangerous conditions were expected to continue until about 9am.
Foggy conditions were also reported in Al Ain, Dubai and Ras Al Khaimah.
"There is a chance of fog formation with a deterioration in horizontal visibility, which may drop even further at times over some coastal and internal areas from 12.30am until 9am," the agency posted on X.
Police in the capital told drivers to use utmost caution.
Motorists are urged to follow changing speed limits displayed on electronic information boards.
"Drive Safely," the force said.
Motorists who fail to follow the revised speed limits face penalties.
It is not the first time the UAE has seen fog this week, with adverse weather also reported on Monday.
