- AIt does not state what a speed governor costs to fit
- BIt assumes that school buses share the road with other vehicles
- CIt rests on the view of a transport officer rather than of a driver
- DIt treats a measure that removes one source of danger as though it removed every source of danger
Step-by-Step Solution
Capping speed deals with one hazard, but a school run can still be made unsafe by worn tyres, a driver who overtakes carelessly, faulty brakes or overcrowding. Removing a necessary part of the danger is not the same as securing safety, which is what 'safe' claims. Cost, shared roads and the officer's designation leave that leap in place.
Answer: D) It treats a measure that removes one source of danger as though it removed every source of danger
