Road safety interventions

Proven road safety interventions are used to create more forgiving roads and roadsides that help ensure simple mistakes don’t cost lives.

Even the best drivers make mistakes, but there are safety treatments Waka Kotahi and other Road Controlling Authorities (RCA) can install so simple mistakes don’t result in someone being killed or seriously injured on our roads.

For technical information on road safety barrier systems, signs and road markings, and street lights, see our road engineering page.
