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

Dis the answer hope this
