Frsc commissions speed limit producing plant in lagos

I think there may be a slight mistake in your question. The FRSC (Federal Road Safety Corps) is a government agency responsible for ensuring road safety in Nigeria, but it's not possible for them to commission a "speed limit producing plant" in Lagos or anywhere else.

Speed limits are not manufactured or produced, but rather are set by authorities to regulate the maximum speed at which vehicles can travel on a particular road or highway. The FRSC, along with other road safety agencies, sets speed limits based on various factors such as road conditions, traffic volume, and safety considerations.
