Cycles of all sorts

Best practice puts the cyclist's wheels more or less where the nearside wheels of the motor traffic would normally go (the "secondary riding position") or, at points of particular danger such as junctions and width restrictions, in the centre of the lane (the "primary riding position" or "taking the lane").

The majority, 73% according to UK data, of car/cyclist collisions occur at junctions or "junction type" locations. Analysis of T-junction  and Roundabout collisions has indicated that failure to yield by entering motorists is a significant accident type. Other significant collision types involve turning-motorists failing to yield to oncoming cyclists and so-called "hook" or "overtake and turn" type manoeuvres. Expert opinion has it that, having taken due account of the nature and speed of any following traffic, cyclists may best protect themselves from such collisions by adopting a prominent road position approaching junctions.

This has two functions: first, it places the cyclist where drivers are actively looking. Second, motorists must "overtake" so may be discouraged from simply driving past the cyclist and then turning across them. Similarly, away from junctions, a prominent position correctly communicates the space the cyclist needs and makes passing a matter of overtaking properly, rather than squeezing past. Additionally most minor injuries to cyclists, possibly up to 85%, result from simple falls. Arguably, keeping out from the kerb also keeps the cyclist away from potential hazards such as drainage grates, gutters, potholes, roadside debris, loose gravel and glass etc. However, a sense of caution is required, what works in urban conditions for someone like a young adult sports-cyclist may not work for someone else who is less able or experienced. As with all road users, cyclists should try to exercise common sense and use gradual experience to build up to new traffic situations.

The advice on positioning contrasts with a lot of information historically given out in basic cycle training for children, and appears to conflict with the vehicle codes in a number of jurisdictions, which will often require a cyclist to ride as far to the right (in left-hand drive countries) as possible. Many drivers also feel that a cyclist has no right to use the road, and that cyclists should be as close to the margin as possible so as not to interfere with their speedy passage. It is worth remembering that no highway code is intended to actively endanger life; the wording may be careless or possibly ignorant but should be interpreted as meaning as far toward the margin as is consistent with safety - and that might mean in the middle of the lane.
