Final answer:
TC 545.059 mandates that drivers must navigate around a rotary traffic island to the right side to ensure traffic flows smoothly and reduces accident risks.
Step-by-step explanation:
According to TC 545.059, an operator moving around a rotary traffic island shall drive only to the right of the island. Rotary traffic islands, also known as roundabouts, are designed in such a way that vehicles maneuver around them in a counterclockwise direction in the United States, staying to the right-hand side of the island. This regulation is set to ensure the smooth flow of traffic and reduce the potential for accidents. It is important for drivers to follow these rules to maintain order and safety on the roads.
