In the latest version of the Highway Code (29 January 2022) a 'hierarchy of road users' was introduced. This is the principle that those in charge of the vehicles that can cause the greatest harm in the event of a collision bear the greatest responsibility to take care and reduce the danger they pose to others. At the top of this hierarchy are drivers of motor vehicles (including therefore quad bikes) who have a responsibility to cyclists, horse riders, drivers of horse-drawn vehicles and pedestrians. While this hierarchy does not constitute a legal presumption in respect of apportioning blame for an accident, the Highway Code is an approved code of practice and can be used as part of evidence in a Court.
