At least on the east side of the state, if a road doesn't have a
speed-limit sign, the controlling law is usually RCW 46.61.400(1)
("reasonable and prudent speed") rather than RCW 46.61.400(2) (default
numeric speed limits).  If the county hasn't done an engineering survey
to determine a safe speed, it's also unlikely that the road was
constructed in a way that permits driving safely at 50 mph.
