Proceed with caution.
If cars approaching from opposite directions reach an intersection simultaneously, the general rule is to yield to the vehicle on the right. This means that the car on the right has the right of way and can proceed through the intersection first. If both cars are at a stop sign or a four-way stop, the car that arrived first should go first. If it is unclear who arrived first, it is best to communicate with the other driver to determine who should proceed first.

Generally it means that the cars on the other side of the line will be travelling in the opposite direction as you are. A white line means that the traffic is facing the same direction as you, or that there is no travel across the line (shoulder).
Force only takes place in the direction of the motion. It cannot be any other way. It could be argued that the action of a cars tyres on the road applies to your question. The car moves forward while the tyres push the earth in the opposite direction. However the tyres are the motion supplying the force and not the car moving in the opposite direction..
