National speed limit

A road speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed. Occasionally there is a minimum speed limit. Speed limits are commonly set by the legislative bodies of national or local governments.

The following tables show various jurisdictions' default speed limits (where applicable) that apply to different types of vehicles travelling on three different types of road. Actual speed limits may range beyond these values. Speeds are listed in kilometers per hour. The enforcement tolerance is specified in km/h or percentage above the stated limit. For the United Kingdom and the United States, the speed limit is also listed in miles per hour in brackets. Germany, with its Autobahns, is the only country without a general speed limit on its highways. The Isle of Man is the only jurisdiction without a general speed limit on rural two-lane roads.

7 km/h over in Western Australia

Generally 10% over speed limit in other states, but a ticket will be given for less when detected by fixed speed camera. However, new laws may see the drivers issued with a ticket for exceeding 2 km/h over the posted speed limit. Heavy penalties apply for speeding in Australia.

Beyond 20 km/h fine is net income based with no upper limit (!)

Motorways: 130 (110 in rain).

Two or more lanes per direction: no speed limit / 130 advisory.

Police enforcement varies depending on jurisdiction, officers, traffic flow and types of street, but 20 km/h above speed limit on expressway and 15 km/h above limit is tolerated on other streets. Some jurisdictions, such as Tokyo Metropolitan Police, releases the list of traffic enforcement locations on their websites.
