What is a default speed limit?

A default (or national) speed limit is the limit that applies on a given road type when no sign says otherwise. Countries set defaults for built-up urban roads, open rural roads, and motorways, which a posted sign can then override up or down.

Does Germany really have no motorway limit?

On much of the Autobahn there is no fixed maximum, only an advisory speed of 130 km/h. Many sections do carry posted limits, and in poor weather or heavy traffic limits apply, but unrestricted stretches remain.

Why does the table switch between km/h and mph?

Most of the world posts limits in km/h, but the United Kingdom and United States use mph. The unit toggle converts every figure so you can read the table in whichever unit you drive in, using the exact factor of 1.609344 km per mile.

Are these the exact limits everywhere in the country?

No. They are the typical defaults. Actual limits vary by specific road, are lower in school zones or roadworks, and in federations like the United States and Australia are set by state, so always obey posted signs.

What happens in bad weather?

Several countries reduce limits in rain or snow — France drops its motorway limit to 110 km/h in rain, and Finland lowers limits in winter. The notes flag the best-known cases, but local rules always apply.

Default speed limits, country by country

This reference shows the default national speed limits for the three main road types — urban, rural, and motorway — across countries worldwide. You can search for a country and switch the whole table between km/h and mph, which is handy when driving abroad in an unfamiliar unit.

How it works

A default speed limit is the value that applies on a road type when no sign overrides it. Countries legislate separate defaults for built-up urban streets (commonly 50 km/h, lower in the UK and US), open rural roads (often 80–100 km/h), and motorways (typically 110–130 km/h). A posted sign always takes precedence, and limits drop further in school zones, roadworks, and bad weather. Conversion between units uses the exact factor 1 mile = 1.609344 km, so 70 mph is about 113 km/h and 130 km/h is about 81 mph. The German Autobahn is the famous outlier, with long unrestricted stretches and only an advisory 130 km/h.

Tips and notes

Toggle to mph before driving in the UK or US, and back to km/h for the rest of the world.
Urban defaults are trending downward — Spain and South Korea have cut city defaults to improve safety.
These are defaults only. Posted signs, road class, weather, and within-country (state) rules always override them, so drive to the signs you see.
