When a red light and an amber arrow light are displayed together, which vehicles can proceed in the direction of the arrow?

When a red light and an amber arrow light are displayed together, the amber arrow indicates that vehicles can proceed in the direction of the arrow, but only under specific conditions. The rules governing traffic signals allow streetcars to move in the direction indicated by the amber arrow while still requiring them to adhere to the priority of pedestrians and other vehicles.

Meanwhile, light vehicles (cars, motorcycles, etc.) are not permitted to proceed in the direction of the arrow due to the red light, which signals that they must stop. The combination of a red light with an amber arrow is specifically intended to allow only the movement of streetcars, making it important for drivers of light vehicles to know that they must remain stationary.

This understanding aligns with the traffic regulations to ensure safety at intersections, where conflicting movements may occur.
