Parts of the UAE were shrouded in dense fog on Monday morning as thousands of motorists hit the roads for the back-to-school commute. Visibility was hampered in Dubai and Abu Dhabi as misty weather rolled in. Abu Dhabi Police reduced speed limits to 80kph on some routes, as the National Centre of Meteorology issued a weather alert. The NCM said foggy conditions could persist until 8.30am, with coastal and internal western areas affected. Temperatures and humidity remain high across the Emirates, with a hot and hazy day forecast. The worst fog swept across the country before 7am, with skies clearing shortly after on one of the busiest days of the year on the country's roads. Police forces across the country have put safety plans in place to deal with an expected increase in traffic during Monday's peak drop-off and pickup periods. More than one million pupils are expected to return to classrooms in the UAE.

The initiative aims to reduce accidents and improve road safety.
