The rules of the road in the United Kingdom are governed by the Highway Code, which sets out the regulations and guidelines for all road users. Some key rules include driving on the left-hand side of the road, giving way to pedestrians at zebra crossings, obeying speed limits, using indicators when changing lanes or turning, and not using a mobile phone while driving unless it is hands-free. It is also important to follow traffic signs and signals, wear a seatbelt at all times, and not drive under the influence of alcohol or drugs. Failure to adhere to these rules can result in fines, penalty points on your driving license, or even disqualification from driving. It is essential to familiarize yourself with the Highway Code before driving in the UK to ensure the safety of yourself and others on the road.
