What does a solid white longitudinal dividing line (puna linija) accompanied by an adjacent dashed white line (isprekidana linija) on the roadway mean?

1. Vehicles travelling on the side of the dashed line may cross it to overtake or turn; vehicles on the side of the solid line are strictly forbidden from crossing it
2. Both lanes may cross the lines freely if no oncoming traffic is visible
3. Neither lane may cross the lines under any circumstance
4. The road is converting to a bus-only lane
