Highway Code Rule 180

Wait until there is a safe gap between you and any oncoming vehicle. Watch out for cyclists, motorcyclists, pedestrians and other road users. Check your mirrors and blind spot again to make sure you are not being overtaken, then make the turn. Do not cut the corner. Take great care when turning into a main road; you will need to watch for traffic in both directions and wait for a safe gap.

Remember: Mirrors – Signal – Manoeuvre

Rule 180: Position your vehicle correctly to avoid obstructing traffic
