Several left-turn-on red signs used to reduce congestion across the city will be removed for not complying with newly enforced road rules.

The 48 signs were gradually implemented since a successful trial in 2013, and were introduced to improve congestion and increased pedestrian safety on Brisbane’s roads.

The signs will be gradually removed in an effort to match Queensland’s signage rules with those of New South Wales.

State Opposition Leader Deb Frecklington says the signal is a simple and effective way to help bust congestion, and to keep pedestrians safe we just need more signage.”
