Did the reduction of the daytime maximum speed to 100 km/h result in fewer crashes?

Answer

Since March 2020, maximum daytime (6 am to 7 pm) speed limit on all motorways in the Netherlands has been 100 km/h. The measure was introduced to help alleviate the nitrogen problem. In theory, a reduction of driving speed will lead to a reduction in casualties. It cannot yet be determined whether this has actually happened. Moreover, the introduction of the speed limit reduction exactly co-incided with the first COVID19 lockdown. That is why the lockdown mobility effects (exposure) cannot be decoupled from the effects of the limit reduction (lower risk).

Speed and speed management

If the average speed on a road increases, crash risk also increases, as does the risk of a serious outcome.
