Overview
- Authorities positioned the mobile speed camera uphill between the Thürmsdorf turnoff and the Festung Königstein entrance, by the Festungsberg bus stop.
- It records traffic heading toward Pirna on a stretch where the maximum speed is 70 km/h.
- The system is an automated Enforcement-Trailer operating from a closed housing without on-site staff.
- The trailer is clearly marked, video‑monitored, and triggers a light signal if someone approaches too closely.
- The county rotates two such units; this trailer was previously in Heidenau, where it logged 4,580 violations in 51 days in a 50 km/h zone.
