Lower speeds save lives - the case for changing limits
1 Mar 2019
While speed may not be a major factor in collisions that result in slight injuries, speed is a major factor in more serious accidents.
In a SPACE for Gosforth article 20 mph - the right speed for Gosforth's children they shared some data on the increasing likelihood of a pedestrian or cyclist being killed or seriously injured (KSI) as vehicle speeds increase.
| Car Speed | All Adults KSI | 70 Year Old KSI |
| 20mph | 17% | 30% |
| 30mph | 40% | 70% |
| 40mph | 80% | 90% |
Even a few miles per hour difference at 30mph could make a significant difference to the chances of someone's survival, and is negligible in terms of time saved on a journey.
