Signs Giving Warnings
What are Warning Signs?
Warning signs are usually red triangles pointing upwards, with a symbol or words on a white background.
They warn of hazards you might not otherwise notice in time — such as bends, hills, or hump bridges.
The symbol tells you what the hazard is; you must then decide how to respond safely.
Examples
Narrowing Roads
Shows which side (or both sides) of the road narrows. Avoid overtaking until you’ve assessed the situation.
Children
Warns you to look out for children, especially near schools or playgrounds.
Additional plates may say “School”, “Playground”, or “Patrol”.
Be alert for school crossing patrols and follow their instructions.
Low Bridge
Indicates restricted height ahead. Even if your vehicle is not tall, be aware that large vehicles may need to move towards the centre of the road for clearance.
Junctions
Shows the type of junction ahead — such as T-junction, crossroads, roundabout, or staggered junction.
The thicker line on the symbol shows which route has priority.
Sharp Change of Direction
Chevrons or reflective roadside posts may be used to warn of sharp bends or curves.
They often reinforce earlier warning signs and mark the safe direction of travel.
Other Hazards
A general hazard sign (red triangle with an exclamation mark) is used when there’s no specific symbol.
A plate underneath explains the hazard, e.g. “Hidden dip” or “Uneven road”.
