23. Quay
A quay is a constructed area beside a river, canal, harbour or other body of water, commonly used for loading, unloading, mooring vessels or providing waterside access. A road may run alongside the water or lead directly towards the quay edge.
In road traffic, a quay warning indicates a risk that a vehicle could leave the road and enter the water. Drivers should reduce speed, observe the road layout carefully and keep a safe distance from the waterside edge.
