Why safe speeds matter

The Safe Speed component of Towards Zero is concerned with setting appropriate speed limits and travelling at safe speeds that are right for the conditions. If speed limits are set appropriately and drivers travel within those limits, the effectiveness of initiatives implemented in the road or vehicle space are enhanced and help reduce road trauma.

For our fragile bodies, even a small difference in speed can mean the difference between life and death. This is especially true for vulnerable road users such as pedestrians, motorcyclists and bicycle riders and especially children and older people.
