Thick fog blanketed large parts of the UAE on the morning of Wednesday, October 7, prompting the National Centre of Meteorology to issue a red alert as visibility dropped below one kilometre across Abu Dhabi and the northern emirates. Abu Dhabi Police responded by temporarily capping speeds at 80kph on several key roads, including the E11 highway linking Dubai and Abu Dhabi, the Abu Dhabi-Al Ain road, Sheikh Khalifa bin Zayed Road, Sheikh Salem bint Buti Road and Ahmed Khamis Al Hamli Road. Motorists were notified of the restriction through mobile alerts as they set out on their morning commute. The fog warning remained valid until 9am, and before 10am Abu Dhabi Police announced on social media that the speed cap had been lifted and roads had returned to normal limits. Under UAE traffic law, drivers exceeding the posted limit by up to 10kph face a Dh300 fine, while exceeding it by between 10kph and 20kph doubles the penalty. Forecasters say similar fog is likely to return in the early mornings until at least Sunday, as cooler temperatures and rising humidity create ideal conditions for fog to form before sunrise. Police have repeated their standard advice for foggy mornings: keep a safe following distance, switch on fog lights, and avoid speeding in low-visibility conditions. Seasonal fog is a recurring feature on UAE roads during the cooler months, and temporary speed restrictions on major highways have become a routine precaution rather than an unusual event, with authorities moving quickly to lift them once conditions clear.
