The Estonian Transport Agency's traffic management center has issued a warning to drivers in western and northern Estonia due to expected fog and the risk of slippery roads overnight. Drivers are advised to exercise caution while traveling on highways, as visibility may be significantly reduced and road conditions could become hazardous. This warning is particularly pertinent given the changing weather conditions that can lead to sudden changes in road safety. As temperatures drop overnight, moisture on the roads could also freeze, compounding the dangers posed by the fog. Therefore, motorists are encouraged to prepare for difficult driving conditions and remain vigilant.
