Driving – Speed Limits

Speed Limits – cars and motorhomes

Unless you see a sign advising otherwise (a red circle with a number on a white background), the default speed limits for a car and motorhomes under 3.5 tonnes are:

30 mph (about 50 km/h)   Urban area (anywhere with street lighting)

60 mph (about 95 km/h)

Other single carriageway roads

70mph (about 110 km/h)

Dual carriageway roads including motorways

You are expected to know what the general rule is

You’ll often meet a Derestricted sign rather than an explicit speed limit sign when coming out of a restricted area.

City centres and residential areas

Increasing there are 20 mph (30 km/h) limits in city centres and residential areas including most of Edinburgh except some radial routes.   Sometimes these are advisory (a green rather than a red circle) but take the advice.

You might come across some Home Zones where the limit is 10mph.

Other vehicles

Please don’t get cross with other vehicles travelling more slowly: the bigger motorhomes, those towing anything including caravans, most commercial vehicles, buses, are limited to 50mph on single carriageway roads and 60mph on dual carriageways and motorways

The heaviest lorries are limited to 40mph on single carriageway roads and 50 mph on dual carriageways.
