Anyone driving to Nakuru should be aware that there is a speed trap. It’s situated just before Naivasha as you descend on the last section of good road (many people cruise at above 140 Kmh) You have to pay a bond of Kshs 3,000 (not a bribe) to enable you to continue with your journey, otherwise your car will be impounded and you will go to jail till your case is heard. The operation is manned by a special police unit (not Naivasha cops) and if you live in the US or Canada, check out speedtrap.org for speed traps in your area.
