The largest myth:Is the roundabout like a 4-way stop?
Not really. The main similarity is that both roundabouts and 4-way stop intersections do not have signals. The differences include: 4-way stops yield to the right, roundabouts yield to the left --like a right turn on red-- because the circulating traffic comes from that direction. At 4-way stops, each direction gets a turn in order. At roundabouts, each driver chooses a safe gap to enter and no driver “gets a turn.”
