Answer
Figure 1 shows the development of the number of serious road injuries between 2000 and 2021 [12] [13] [14]. Since 2007, the trend in serious road injuries has mostly been upward. The decrease in MAIS3+ casualties between 2013 and 2014 can be attributed to a change in the determination method [1] [15]. In 2020 and 2021, the number of serious road injuries was lower than was to be expected considering the trend up to and including 2019. This was probably partly due to the COVID-19 social distancing measures, which resulted in less traffic.
