The aspect is a necessary but INSUFFICIENT condition. Also needs dispatch authority, whether this is given via RA indicator, a buzzer code from the guard or the old fashioned whistle and waving of the green flag.
None of these should be given unless the signal is off, but itis still the driver's responsibility to check.
