Final answer:
In a modern roundabout, drivers should not speed through the intersection but should adhere to the posted speed limit, yield to circulating traffic, and avoid overtaking within the roundabout.
Step-by-step explanation:
When navigating a modern roundabout, there are several rules of the road to be followed for safety. You should not speed through the intersection irrespective of the posted speed limit. Safe driving practices require that you slow down before entering the roundabout, yield to any traffic already circulating, and certainly do not attempt to overtake other vehicles within the roundabout. This ensures the safety of all road users, allowing for an orderly and predictable flow of traffic around the circular intersection.
