The presence of four vehicles and a pedestrian approaching an intersection at the same time might represent a situation to _______ the risk (and move forward to an alternative maneuver at a different intersection) of completing the maneuver.
Four vehicles (assuming they approach from four different directions) and a pedestrian constitute a dangerous, complicated situation. Say, you want to turn left, but actually you can drive straight and turn left on the next intersection - this might be a safer option.
This option means that you would avoid the risk - "avoid" fills the gap!
