Changes to the Highway Code
"Overtaking a cyclist typically does not require going to the opposite lane..."
If you are in the UK, you may not need to go completely into the opposite lane, but you will overlap it by a large margin, according to the Highway Code. The new clarifications say that you should leave at least 1.5 (5 feet) when overtaking cyclists. Similarly cyclists should cycle at least 0.5m (1.5 feet) from the kerb "when riding on busy roads with vehicles moving faster than them."
