Yes, many Australian cites have a 40km/h speed limit.
Hobart already has a 40km/h speed limit throughout the Hobart waterfront and Battery Point area, in the popular dining strip in North Hobart and around schools.
Moonah and Glenorchy also have 40 km/h speed zones through their busy retail strips. In some areas of Hobart, lower speed limits have been previously implemented to ensure higher levels of safety for all road users.
