Logical Steps
The Driver drives the car till intersection is reached.

If the intersection has a stop sign and the road is busy as well, the driver will stop the car till the road clears.
If the intersection is clear and the driver wants to take a turn, the driver turns on the car’s indicator and takes the turn. If the intersection is busy, he/she waits till the intersection is clear.
