Ok, I dug a little deeper and found various reports that show contradictory numbers, so I had to look at how these numbers are assembled. The way accidents are registered is quite complex. This site has the best, most encompassing info: https://www.star-verkeersongevallen.nl/en-GB/Map#5.1939/52.1097/6.0000/0.0000/0

For 2025 there is a strong increase compared to 2024 but unfortunately they don't give the comparable number for 2024 so I can't put a number on it.
