European transport authorities are preparing to introduce a new white traffic light signal on public roads, adding to the existing red, amber, and green system. The white light is designed to communicate with connected and autonomous vehicles, signaling that a vehicle's onboard system is managing the driving. High infrastructure costs and the need for widespread vehicle-to-light communication technology remain the main obstacles to rollout. For tourists driving in Crete, no immediate changes are expected. The existing traffic light system remains in place, and visitors should continue to follow standard road rules. This development is a long-term European initiative and is unlikely to affect road conditions on the island in the near future.
