Left Turn Detection System
Left turn detection helps prevent rear-end collisions by warning motorists, in real-time to vehicles stopped ahead waiting to turn.
The left turn detection system is a custom solution commonly used in work zones with single lane traffic where a turn lane is not present. It‘s also effective in non-work zone applications where stopped traffic can‘t be seen due to curves and hills.
