Can I proceed to the next step or would you like more detail?

Turn right on Allison Road, right after the McDonalds. Can I proceed or do you require more detailed instructions?
I don't understand. Can I have more details?
Turn right on Allison Road, right after the McDonalds. You should see a park on your right. Can I proceed or do you require more detailed instructions?

Turn left after the park and your destination will be on the left. Do you know how to reach your destination or would you require more detailed instructions?
Is that the last step? only 3 steps?
That is the last step unless you need more detailed instructions.

Is there anything else that I can do for you?
