Large vehicles, especially trucks with trailers, often need extra space in roundabouts, and may take up more than one lane when turning. Many roundabouts, like the one at at 67 Street and 30 Avenue and 67 Street and Orr/Johnstone Drive, have truck aprons to accommodate large vehicles. A truck apron is a raised concrete area near the centre of the roundabout that gives large vehicles extra space while navigating the roundabout. The dedicated right turn lanes in this roundabout will also make it easier for large vehicles to move through the roundabout.
All of the same rules of the road apply for large vehicles in roundabouts. Drivers should enter the roundabout in correct lane for their destination, as their size allows.

The Truck Encroachment sign reminds drivers that large vehicles may use both lanes of the roundabout and to not attempt to pass large vehicles.
