Do most crashses happen on high-speed roads?
Two thirds of collisions in which people are killed or seriously and slightly injured happen on roads with a speed limit of 30mph or less.

Cyclists are also vulnerable in built-up areas, with more than half of cyclist deaths (59 of 97) and serious cyclist casualties (3,969 of 4,469) occurring on built-up roads.
This is why the Department for Transport encourages traffic authorities to consider the introduction of more 20mph limits and zones, over time, in urban areas and built-up village streets that are primarily residential, to ensure greater safety for cyclists and pedestrians. RoSPA also encourages planners to pay attention to lower speeds in built-up areas, with active travel like walking and cycling promoted as a positive option.
