A one-stop-shop for all your scofflaw argument needs.
The aim here is to present various percentage-based statements about who’s breaking which laws on the road (plus who’s indulging in which dangerous behaviours), backed up with references. I’ve tried to include only statistics which are derived from either (a) reasonably convincing research studies, (b) reasonably trustworthy evidence such as conviction rates and police data, or (c) “self-admission” surveys (ie those involving respondents confessing to their own behaviour, which are highly unlikely to overestimate non-compliance) – but, as with all statistics, handle with care. If you have any sense, you should realise that apparently similar phrasing below does not necessarily equate to directly comparable data once you look at the source.
If you know of further sources which can be added, please leave a comment; I’ll check it out, remove the comment, and replace it with an entry if it’s usable. Thanks.
Stopping at junctions
- 14% of drivers jump a red light at least twice a month – Direct Line survey, August 2011
- 10% of cyclists found to jump red lights – Sunday Times operation, November 2013
A note on red light jumping: most statistics do not account for the opportunity to jump lights. Two-wheeled vehicles (bicycles and motorbikes) have much greater opportunity, because they can filter; whilst full-lane-width vehicles must remain behind any which have not jumped the lights. Hence in the vast majority of cases, where opportunity is not accounted for, the statistics distort the compliance picture in favour of full-width vehicles. For more discussion, see a Response to the IAM and a Response to The LDTA.
