A Google Maps recommendation for a prohibited left turn at the Połczyńska and Powstańców Śląskich junction in Bemowo sparked three accidents over two days, leaving riders injured and traffic gridlocked.
Mistranslated Trip Steering Suggestion
Google Maps indicates that while driving eastbound on Połczyńska toward Warsaw’s center, a left turn onto Powstańców Śląskich is possible. In reality, a no‑turn sign forbids the maneuver. Blind reliance on the navigation turns the intersection into a collision hotspot.
15 October: Motorcycle‑Car Collision
In the afternoon, a car traveling from Ożarów on Połczyńska made a prohibited left onto Powstańców Śląskich, striking a motorcycle. The rider suffered serious injuries and was taken to hospital. Traffic flow halted during the evening peak.
16 October Morning Accident
A vehicle making a forbidden left at the same intersection forced a Skoda to yield, resulting in a side‑impact collision.
16 October Late‑Day Collision
Around 4 p.m., a Volvo driver again turned left against the sign. A heavy‑duty Honda collided with the Volvo, damaging both cars and local infrastructure. Two people were hospitalized. This was the second incident that day mirroring the motorcycle crash.
Why Drivers Listen to Phones instead of Signs
Navigation offers a sense of certainty, especially in unfamiliar or congested areas, but road safety is governed by on‑site signs. When a map guides a maneuver that contradicts signage, drivers should obey the traffic organization and avoid entry into collision‑prone lanes.
