On horizontal curves, motorcyclists will generally adopt a line that follows the vanishing point. However, if a roadside object such as a tree or field gate interrupts the vanishing point then motorcyclists may veer towards that object. This can then result in a loss of control collision and as already highlighted within the chapter, when a motorcyclist is involved in a collision with a roadside feature it can result in fatal or serious injuries. To reduce this risk, motorcycle trainees are often taught that ‘Where You Look Is Where You Go’ (WYLIWYG).

Treatment

: Where there are safety concerns of road users losing control on a curve, the WYLIWYG principle can be introduced. WYLIWYG uses a series of flexible delineator post to draw the focus of motorcyclists and drivers to the vanishing point of the curve and prevents distraction by roadside objects

Flexible delineator posts are placed in the margin at regular intervals, extending both around the curve as normal and also for some distance after the curve until the vanishing point starts to move away from the rider’s view into the subsequent tangent.

Designers need to give consideration to passive safety when proposing the installation of flexible delineator post. Providing flexible delineator post can have maintenance implications, since it is essential that the posts remain visible to maintain their effectiveness.
