Each authority provides all officers with copies of appropriate bylaws, conditions and agreed methodologies/reporting mechanisms for dealing with defective vehicles and other issues from other areas.
Mae pob awdurdod yn rhoi copïau o is-ddeddfau priodol, amodau a methodolegau/systemau adrodd y cytunwyd arnynt ar gyfer ymdrin â cherbydau diffygiol a materion eraill o ardaloedd eraill i bob swyddog.
