May I say to the gentleman in his car today who, while one vehicle was pulling in right in front of me while I cycled, blasted his horn from behind me, then overtook me driving on the wrong side of the road towards a blind crest and corner, steering with one hand while he wound down the window with the other hand and pointed at me as looked me in the eye and said “You have to pull into the side of the road, you’re causing a traffic jam” before driving on and blasting his horn again, I was not breaking the Road Traffic Act.
For the purposes of those who read English, let me quote the Road Traffic Act of 1991.
7. For section 28 of the [1988 c. 52.] Road Traffic Act 1988 there shall be substituted—
28. — (1) A person who rides a cycle on a road dangerously is guilty of an offence.
(2) For the purposes of subsection (1) above a person is to be regarded as riding dangerously if (and only if)—
(a) the way he rides falls far below what would be expected of a competent and careful cyclist, and
(b) it would be obvious to a competent and careful cyclist that riding in that way would be dangerous.
(3) In subsection (2) above “dangerous” refers to danger either of injury to any person or of serious damage to property; and in determining for the purposes of that subsection what would be obvious to a competent and careful cyclist in a particular case, regard shall be had not only to the circumstances of which he could be expected to be aware but also to any circumstances shown to have been within the knowledge of the accused.
For reference, for those who can read English and understand computers enough to be able to navigate the Internet and are legally allowed to surf the Internet, here’s the full text of the Road Traffic Act 1991.
