A compass uses Earth's magnetic field to determine which way is north. By aligning the compass needle with the north direction, you can easily find your orientation and determine other cardinal directions.
Traffic, a conveyor belt, a river current, and a moving walkway can proceed in the opposite direction.

Thermodynamics. Specifically, the reaction will proceed in the direction that leads to a decrease in Gibbs free energy. If the Gibbs free energy change of the reaction is negative, it is more likely to proceed in the forward direction.
Vehicles at a 4-way stop intersection should proceed in the order they arrived, regardless of direction.
No, it is not true. Reactions can be reversible, meaning they can proceed in both directions depending on the conditions. If a reaction releases energy in one direction, it may require an input of energy to proceed in the opposite direction, but it can still occur.
Proceed with caution.
The factors that determine whether a chemical reaction will proceed in an energetically favorable or unfavorable direction include the difference in energy between the reactants and products (enthalpy change), as well as the entropy change and temperature of the system. If the overall change in energy is negative (exothermic) and the increase in disorder (entropy) is positive, the reaction is likely to proceed in a favorable direction.

A green arrow typically indicates that you can turn or drive forward in the direction it is pointing. It is a signal that you have the right of way to proceed in that specific direction.
After passing through a converging lens, a focal ray from an object will proceed through the focal point on the opposite side of the lens.
The right arrow sign indicates that vehicles should proceed in the direction pointed by the arrow.
