1) Intersections require alertness as multiple road users cross paths. Signaling your intentions and understanding right-of-way rules is important for safety.
2) Traffic lights indicate who has the right-of-way using steady green, yellow, and red lights as well as left turn arrows. Stop signs require a complete stop before proceeding with caution.
3) Yield signs mean letting through traffic pass before entering. Traffic circles and roundabouts require yielding to vehicles already circulating and following the traffic flow clockwise.
