In traffic diagrams, a solid double yellow line typically indicates that traffic is flowing in opposite directions. This line separates lanes for vehicles traveling in opposite ways and prohibits passing. In some cases, a broken line may also indicate lanes going in different directions, but the solid double yellow line is the most common indicator of opposing traffic flow.
Yellow
A blank line in traffic flow diagrams typically indicates a separation between different streams of traffic but does not specifically show traffic flowing in the opposite direction. Instead, it often represents a gap or a neutral zone between lanes or directions. To indicate opposing traffic flow, arrows or other symbols are usually employed.
If it's white, it shows that lane changes are legal, and that traffic in the adjacent lane travels in the same direction. If it's yellow, it indicates that passing is legal (when safe to do so) and that traffic in the adjacent lane travels in the opposite direction.
A galvanometer shows opposite deflection because the current flowing through it causes a magnetic field that interacts with the permanent magnet inside the galvanometer. The direction of the magnetic field determines the direction of deflection of the needle, resulting in opposite deflection depending on the direction of current flow.
A single broken line on the road indicates that traffic can flow in opposite directions. This line typically separates lanes for vehicles traveling in opposite directions, allowing for safe passing. Drivers are permitted to cross this line when overtaking another vehicle, provided it's safe to do so.
If the green arrow shows for the direction you want to turn then you obey the green arrow, the red light is for all other traffic. The green arrow basically overrules the red light for the direction of the arrow.
You may turn in the direction the arrow is indicating. No other maeuvers are allowed.

The arrow on magnetic field lines shows the direction in which a north magnetic pole would be drawn if placed in the field at that point. This convention is used to represent the magnetic field direction moving from north to south.
