In Wales, as in the rest of the UK, you must drive on the left-hand side of the road. All vehicle occupants must wear seat belts at all times, and talking on a cell phone while driving is strictly prohibited. Speed limits vary by road type: 48 km/h (30 mph) in built-up areas, 97 km/h (60 mph) on single-lane roads, and 112 km/h (70 mph) on dual-lane roads and freeways. Remember to always carry a valid driver's license, identification and your insurance documents while driving.
