You reach a T-junction in Papua New Guinea where no stop sign, give way sign or signal is exhibited, and another vehicle is approaching the junction on your right. What do the Road User Rules 2017 require?

1. Give way to the vehicle on your right, and approach the junction at no more than 25 km/h
2. Proceed first, because a vehicle on the continuing road always has priority over one on the terminating road
3. Give way only if the other vehicle is signalling a turn across your path
4. Proceed first if your vehicle is the heavier or larger one
