Who may use the raised truck apron around the center island of a roundabout?
- Large commercial trucks and trailers negotiating a tight turning radius
- Any passenger car that wants to shorten the circulating path
- Bicyclists whenever the roundabout has two entry lanes
- Pedestrians crossing between the entry and exit points
Answer: Large commercial trucks and trailers negotiating a tight turning radius. The truck apron exists for large commercial trucks and trailers whose rear wheels need additional room to negotiate a tight turn around the center island. Passenger cars should remain on the circulatory roadway, so using the apron to shorten a route is improper. It is not a general bicycle or pedestrian path. Drivers in a car should choose the marked entry lane, yield to circulating traffic, and continue counterclockwise without climbing the raised pavement. The visual cue is simple: the apron is truck turning space, not an extra passenger-car lane.
