I don't think you have to tell them anything. They will know by how you look.

no
Look before you leap.
both ways and ahead for traffic before proceeding look both ways before turning (left and right) Though traffic signals at intersections may provide a reasonable guide by which to estimate traffic patterns, do not rely on them to protect you from motorists running through red lights or STOP signs. Always look left, right and left again before entering an intersection.
