Highway Code Rule 204
The road users most at risk from road traffic are pedestrians, in particular children, older adults and disabled people, cyclists, horse riders and motorcyclists. It is particularly important to be aware of children, older adults and disabled people, and learner and inexperienced drivers and riders. In any interaction between road users, those who can cause the greatest harm have the greatest responsibility to reduce the danger or threat they pose to others.
