Warning signs for road work will warn you of hazards ahead, such as roundabouts, crossroads, dangerous bends or anything else that would call on you to drive more carefully.
You should always take special care when you see a warning sign. If you fail to observe these signs you could create an emergency. Like other warning signs, these are diamond or rectangular in shape and have a black border and black symbols or text. However, they are orange in colour instead of yellow.
