In 2024, police in Polderwetering registered 2 traffic accidents, of which 1 with injury and none fatal.
Registered accidents (BRON, Rijkswaterstaat); material-damage-only accidents have not been systematically registered since roughly 2010 and are not comparable between areas. This area shows only accidents with an exactly known location (roughly 80-85% of all registered accidents); the rest is known only at street, intersection or gemeente level. The comparison with the gemeente therefore also uses only the gemeente's exactly-located accidents, which is why that figure is lower than on the gemeente's own page.
