Turbo roundabout is a design developed by Bertus Fortuijn. Its design, when combined with appropriate signage, dramatically improves safety and traffic flow, and is surprisingly easy for the unfamiliar driver to navigate.
There are two types of roundabouts: Single-lane roundabouts and multi-lane roundabouts. There are a few key things to remember about driving roundabouts: 1  Yield to drivers in the roundabout. 2  Stay in your lane; do not change lanes.3  Do not stop in the roundabout.nce a gap in traffic appears, merge into the roundabout and proceed to your exit. Look for pedestrians and use your turn signal before you exit. If there is no traffic in the roundabout, you may enter without yielding. Watch a video on how to drive a roundabout.
