What is the legal rule regarding overtaking on the right side of another vehicle in Chile?

1. Overtaking on the right is always permitted on all roads
2. It is permitted only in three cases: the vehicle ahead is making or about to make a left turn, the urban road has three or more lanes in the same direction, or you are passing cycles travelling in the left-hand lane — and never off the carriageway
3. Overtaking on the right is allowed whenever you flash your high beams first
4. Overtaking on the right is legal only on rural single-lane roads
