To this question, there are many point to be covered:
First, maintaining a safe distance from the car ahead of you helps in controlling the congestion. Many times drivers drive the car very close by to the car ahead of them which increases the chances of any accident. So maintaining a safe distance is the first point to remember.
Second, follow the speed limit sign. We all can see the speed limit signs on the road. We have to follow the speed limit in order to avoid any hazard. Over speed and under speed both are the reason for congestion on the road. If the speed limit sign instructs not more than 80, then the speed limit should be between 60 to 70. overspeeding may cause an accident and under speeding may cause congestion for all the drivers driving after you.
Third, Overtake whenever required: Many drivers who are new are afraid to overtake the driver in front of them if they are driving slow. Please make sure that you don't have to be the part of the snail drivers but rather overtake the other drivers who are moving slow but keeping the note of the speed limit.
Fourth, Parking a car. If you go to the narrow roads in Dubai, people park their cars in the middle of the road. Switching on the parking lights and leaving the car on the middle of the road is commonly seen on the narrow roads and resulting in big congestion on the road.
