III. Sharing the road
Driving in roundabouts

Allow extra room alongside large vehicles (trucks and buses). They may have to swing wide on the approach or within the roundabout. Give them plenty of room.

Pull over for emergency vehicles
If you are in a roundabout when an emergency vehicle approaches, continue to your intended exit and proceed beyond the traffic island before pulling over. If you have not entered the roundabout yet, pull over to the right if possible and wait until the emergency vehicle has passed.

Driving a large vehicle in a roundabout
A driver negotiating a roundabout in a large vehicle (such as a truck or bus) may need to use the full width of the roadway, including the central apron (a mountable portion of the centre island adjacent to the roadway) if provided. Prior to entering the roundabout, the vehicle may need to occupy both lanes. Give large vehicles plenty of room to manoeuvre.

Many roundabouts are also designed with a central apron, a raised section of pavement around the central island that acts as an extra lane for large vehicles. The back wheels of the oversize vehicle can ride up on the central apron so the truck can easily complete the turn, while the raised portion of concrete discourages use by smaller vehicles.
