What must an operator of a vehicle do when facing a green arrow signal?

When a vehicle operator is facing a green arrow signal, they are granted the right to proceed in the direction the arrow is pointing. However, this does not relieve them of the responsibility to ensure the safety of others. Yielding to pedestrians who are lawfully in adjacent crosswalks is a crucial part of traffic safety and the law. This means the driver must be vigilant and ensure that any pedestrians who have the right of way in that area can cross safely before proceeding. This requirement promotes a safe environment for all road users, including those on foot.

The other options do not align with the responsibilities associated with a green arrow signal. For instance, proceeding without regard ignores the potential presence of pedestrians. Stopping at the intersection is unnecessary when a green arrow allows for movement, and signaling left before entering the intersection is relevant when making a turn but is not a specific requirement when the green arrow is present.
