“Two cars crashed, then 26 others, whose drivers didn’t keep a safe distance, rammed into one another,” he said.
Brig Al Mazroui urged road users to pay attention to the road and reduce speeds in fog and bad weather.
“Accidents that happen during bad weather conditions tend to be more severe," he said.
He urged motorists to use low-beam lights – not high beam, which can dazzle other road users – and indicate clearly when changing lanes.
“Allow extra time for your journey and check your planned route," he said.
"It’s also advisable to wait for the fog to clear until visibility improves."
