Posted speed limits are based on which of the following

(Select all that apply)

A - condition of vehicle

B - dry pavement

C-good visibility

D - idea conditions

E - common sense

F - speed of other vehicles

Warning: I am not a driver myself so take this response with a grain of salt

I would believe that is is B, C, D (which includes B&C if it meant to say ideal conditions) and E

When driving all of these apply though, however the posted speeds cannot know the car's condition nor the other drivers' soeeds
