Question

Lighted arrows are sometimes used to control turns from a specific traffic lane. A green arrow:

1. Is used only on one-way streets.
2. Means the same as a circular green light, but you must go only in the direction the arrow indicates.
3. Means that you may go only if the green arrow is accompanied by a green light.
4. Points the way to the airport.

Answer 1

A green arrow on a traffic signal means you must go in the direction the arrow indicates, similar to a circular green light. It helps manage the turn movements of vehicles and pedestrian safety at intersections.

Step-by-step explanation:

The question is about understanding traffic signals and the meaning of a green arrow on a traffic light. When you see a green arrow at a traffic signal, it indicates option 2: it means the same as a circular green light, but you must go only in the direction the arrow indicates. This helps control the flow of traffic and ensures that vehicles turn safely without interfering with other traffic movements. Unlike the other options suggested, green arrows are not exclusive to one-way streets, do not require an accompanying green light, and certainly do not point the way to the airport.

In terms of direction and representation, arrows can be used to signify many types of movement or direction, similar to the way vectors are graphically represented in physics. However, in the context of traffic signals, a green arrow is specifically used to manage vehicular turns and pedestrian safety at intersections.
