The Dutch roads experienced their busiest morning rush hour of the year, with traffic jams reaching over 1100 kilometers due to rain and accidents, according to ANWB. Major congestion was noted on various highways, including the A1 and A4, with multiple vehicle collisions reported. Authorities are warning of similar heavy traffic for the evening commute, compounded by the ongoing rain and roadwork closures. This follows a trend of increasing traffic delays due to external factors like recent railway strikes.
