What should a candidate do if an oncoming vehicle on a dark two-lane rural road refuses to dip its high-beam headlights (encandeamento por máximos)?

1. Reduce speed, avoid looking directly at the oncoming headlights, focus your gaze down towards the right-hand edge/fog line of the road, and keep low beams on
2. Turn on your high beams in retaliation to blind the oncoming driver
3. Close both eyes until the oncoming vehicle has passed
4. Swerve across into the oncoming lane
