+You've probably heard about self-driving automobiles, in which the driver is completely dependent on the vehicle for transportation. But for vehicles to reach level 5 autonomy, all traffic regulations must be understood and adhered to.
+Speed limits, no entry, traffic signals, turns to the left or right, children crossing, no passage of heavy trucks, etc. are just a few examples of the various types of traffic signs. The process of determining which class a traffic sign belongs to is known as categorization of traffic signs.
