When driving this route across the UK, remember that we drive on the left-hand side of the road. Motorway service stations are spaced regularly and offer fuel, food, and rest facilities — aim to stop at least every two hours. Be prepared for roundabouts at major junctions; always yield to traffic already on the roundabout coming from your right. Speed cameras are common on UK roads, so stick to posted limits: 30 mph in built-up areas, 60 mph on single carriageways, and 70 mph on dual carriageways and motorways. Check traffic updates before departure to avoid congestion hotspots.
