Anine, on 19 April 2012 - 12:46 , said:: "If you're doing 20 or even 30km/h on an 80km/h stretch of road, then you are obstructing traffic." There is no regulation at all about moving vehicles obstructing traffic. This is largely the cause of the problem. Ignorance. On the whole motorists believe they have the right to the road. Even if cyclists are single file but not hugging the kerb. There is no God given right to hoot at a cyclist riding single file on a public road, even if they are in the middle of the road. Unfortunately both parties are at fault of breaking the law/ignorance. The law says: Motorists It is OK to overtake in the right hand lane, if safe to do so. It is not OK to pass and then cut back onto left until safe It is not OK to drive recklessly just because some cyclists have pissed you off Cyclists It is not OK to ride two abreast UNLESS overtaking so 2 abreast in a paceline is OK It is not OK to overtake if being overtaken ie 3 abreast is out If there is a cycle lane, you HAVE to use it Here is what the law actually says, in lawyer speak: NO. 93 OF 1996: NATIONAL ROAD TRAFFIC ACT, 1996. 63. (1) No person shall drive a vehicle on a public road recklessly or negligently. (2) Without restricting the ordinary meaning of the word "recklessly" any person who drives a vehicle in willful or wanton disregard for the safety of persons or property shall be deemed to drive that vehicle recklessly.
