Priority from the right

[Hasitha]

Hi,

I have a question on priority from right at a junction where there are no traffic signs.
In theory if there is no traffic sign at a intersection, we should give priority for the drivers coming from the right.

Let's say a person who push a motor cycle (still a driver) is coming from our right side. Do we need to give priority for him?
Again, a man who taking a dog also a driver (in theory). If he come from right on the road, do we need to stop our vehicle and need to give priority?

Question 1.
Yes.
Question 2.
A man with a dog is a pedestrian.

He's a pedestrian walking a dog

But if he was herding say sheep or cattle, or walking a horse, you'd need to yield

Thanks for the answers.
Actually in real life it is bit hard to give priority for a man come with a sheep from right. Isn't it?
