Warning road signs rely on bright, reflective print to catch drivers’ attention. We print warning signs in reflective vinyl for mines, farms, estates and contractors. Boldmedia Print Zimbabwe can produce them in sets.
Warning road signs alert drivers to a hazard or change ahead: sharp bends, speed humps, pedestrian crossings, children, animals, junctions, road narrowing or uneven surfaces. They use standard shapes, colours and symbols so the message is understood instantly, and are built on aluminium or steel blanks with retroreflective sheeting so they show up clearly in headlights.
A good warning sign is placed far enough ahead of the hazard for drivers to slow down safely, is the correct size for the road speed, and stays clean and reflective. Unlike regulatory signs, which give an instruction, warning signs give information so drivers can adjust their behaviour, and they are often paired with supplementary plates showing distance or extra detail.
Where it works well
- Speed humps and traffic calming in estates and campuses
- Pedestrian and school crossings
- Sharp bends and blind rises on farm and mine roads
- Heavy vehicle crossings at industrial sites
- Animal and wildlife crossings on lodges and reserves
- Road narrowing, uneven surfaces and drop-offs

Supplying measurements
List the hazards to be signed, the road speed and approximate distances from each hazard to where the sign would stand. Photos of the approach in both directions help us recommend sizes and positions.
Artwork requirements
Standard warning signs follow set layouts, so you only need to tell us the sign type and size. Custom wording on supplementary plates can be supplied as text and we prepare a proof.
Survey and installation
Warning signs need to be set at the right distance before the hazard and at the correct height, which a site visit helps confirm. Public road installations may need road authority approval and traffic accommodation, and underground services are checked before digging.
Maintenance
Clean signs regularly, especially on dusty gravel roads, so they stay reflective. Check posts and faces after heavy rain, impacts or vandalism and replace damaged signs quickly.
Frequently asked questions
How far before a hazard should the sign be placed?
It depends on road speed and visibility; faster roads need more warning distance, and we can advise from photos or a site visit.
Can a distance plate be added under the sign?
Yes, supplementary plates showing distance or extra information can be supplied with the sign.
Are warning signs needed on private roads?
They are strongly advisable wherever there is a hazard drivers may not expect, such as speed humps or pedestrian crossings.
