What is the legal consequence in Angola when a driver refuses to submit to a legally requested alcohol screening test (exame de pesquisa de álcool) ordered by a traffic authority?

1. The driver is barred from driving for 12 hours (impedimento de conduzir); driving during that period is punished as qualified disobedience (desobediência qualificada)
2. The driver receives a minor administrative fine with no further consequence
3. The officer must allow the driver to continue after a verbal warning
4. The officer can only test the vehicle passengers instead
