via M23/A23
Before setting off on this journey, ensure your vehicle is prepared for UK motorway driving. Keep to the left-hand lane unless overtaking, and remember that speed limits are displayed in miles per hour — 70 mph on motorways and 60 mph on single carriageways. Plan rest stops at motorway services every two hours to stay alert. Watch for variable speed limits on smart motorways, shown on overhead gantry signs. Roundabouts are common at junctions, so remember to give way to traffic from the right. Keep loose change handy for any toll roads along your route.
