Travelling by car
As Cameroon being one of the worlds most corrupted countries an easy place for treasurehunters to collect bounty is to stop vehicles at road blocks. Usually you can pay about 2000 CFA ($2) to immediatly pass. If you for some reason now, that something with your papers isn´t right or you have some problem with your car that they could pick on there is a trick that the locals use.

Dealing with officials in Cameroon
Keep your enemies close to you
When the Cameroonians that serve in the army how to go, say from Limbe to Douala they don´t get paid by the army for the trip. So what they do is to hitchhike. If you see a person in army or police suit hitchhiking and you pick him/her up and put her in your frontseat the magic will start. At the roadblocks they can start to wave you in but as soon as they see that a stateofficial is seated in the front seat they will wave you by.
Voilá! That´s how you get past roadblocks in Cameroon and West Africa in general.
