Local Traffic Patrol

Here is the human version of the 'don't back up or your tires will be damaged.' The traffic patrol in Calabar position people at intersections or speedbumps to ensure the cars aren't overloaded (many are), the motorbikes are properly equipped (helmets), and drivers are obeying the traffic rules (outside of stopping at the intersection, not sure on this one). Sometimes a unit of people create a checkpoint in city at differing times and locations. If a driver resists stopping for the patrol, he uses the stick in his hand spiked with nails on your tires.
