Why is traffic so bad when it rains?

The main reason, that most people recognise as the main reason for traffic jams on rainy days, is that cars are driven at a much slower speed. This is because of the decreased stability, visibility and increased reaction time. Which leads to a build-up of vehicles, leading to a queue of traffic.

Does rain affect traffic?

Heavy rain can decrease average speed by 3 to 16 percent. In heavy snow, average freeway speeds can decline by 5 to 40 percent. Low visibility can cause speed reductions of 10 to 12 percent. Free-flow speed can be reduced by 2 to 13 percent in light rain and by 6 to 17 percent in heavy rain.

Why does traffic happen on highways?

Each time drivers slow down or speed up affects the flow of traffic around them. This flow then ripples through the other cars in the area. This carries on to each of the cars behind and causes a slight slowdown. Congestion is caused as these bursts of slowdowns allow time for more cars to enter the roadway.
