Nongovernmental organizations advocating on behalf of road safety and road traffic injury victims vary considerably in terms of their origins, scope and resources. Many were created by people who have been directly affected by a road traffic crash, either through the loss of a loved one or as a victim themselves. For them, road safety is a deeply personal issue, and they bring their passion and conviction to the cause. Their testimonies help to convey a sense of urgency. Other nongovernmental organizations are membershipbased, promoting the rights of specific groups of road users, such as pedestrians, cyclists or motorcyclists. Still others are oriented towards road safety research or policy. Like the professional associations, they make their case based on scientific evidence and the prestige of their members. In terms of their scope, some of the organizations focus particularly on the post-crash response, advocating for improved emergency services and national standards of social, medical and legal care for victims and their families. Others call for, or themselves implement, discrete road safety projects around key factors such as seat-belts, helmets or reflectors for increased visibility on the roads. Some address road safety as part of the broader issue of sustainable mobility. Given their disparate nature, capacities vary greatly in terms of human and financial resources and technical road safety knowledge. Regardless of their background, remit and assets, all nongovernmental organizations serve as advocates in one way or another, and suggestions for ways in which they might do this as strategically as possible can benefit the road safety cause
