What Are Restriction Signs?

Restriction signs communicate specific limits or conditions that apply in a designated area. They tell workers and vehicle operators what speed, weight, height, or access rules apply — ensuring those rules are enforced consistently across a site.

Under AS/NZS 1319-1994, restriction signs use a white background with a red circular border and black text or symbol indicating the specific restriction. This format matches road traffic sign conventions — any driver or site worker recognises it immediately.

Common restriction signs include: 5km/h, 10km/h, 15km/h, and 25km/h speed signs, weight limit and load limit signs, height restriction signs for boom gates and underpasses, forklift speed limit signs, and pedestrian and vehicle separation restriction signs. Every restriction sign in the NSS range is Australian-made. Order online today.

Industries We Supply

Construction & Civil Works — Speed restriction signs are a WHS requirement on all Australian construction sites. Principal contractors and site managers order speed, height, and access restriction signs before site establishment.

Mining & Resources — Mine sites operate large vehicles in close proximity to workers. Speed restriction signs are a critical safety control on all mine roads, ramps, and processing areas.

Warehousing & Logistics — Forklift speed limits and weight restrictions are essential in warehouses and distribution centres to prevent vehicle-related incidents.

Car Parks & Facilities — Car park operators and building managers use height restriction and speed limit signs to protect infrastructure and manage liability.

Frequently Asked Questions

What speed limit applies on construction sites in Australia?

Most Australian construction sites set a speed limit of 10km/h for all vehicles. Some sites implement 5km/h limits in high-pedestrian-traffic areas such as laydown areas and near site amenities. No single universal speed limit applies to all construction sites under Australian law. Each site safety management plan must identify and implement appropriate speed controls for the specific conditions. WHS regulations require that any speed restriction is communicated through clearly posted speed restriction signs. National Safety Signs supplies 5km/h, 10km/h, 15km/h, and 25km/h speed signs for construction sites across Australia.

Are speed restriction signs legally required on Australian construction sites?

Yes. Under Australian WHS regulations, every PCBU must implement and communicate traffic management controls, including speed restrictions, on sites where vehicles operate. Speed restriction signs communicate these limits to drivers and plant operators. Failure to post clear speed restriction signs is a WHS compliance failure. It can result in improvement notices and significant legal liability in the event of a vehicle-related incident. National Safety Signs supplies AS/NZS 1319 compliant speed restriction signs for construction, mining, and industrial sites across Australia.

What weight limit signs do I need for a car park?

Car park operators must display weight limit signs at all entry points, on each level, and at any point where the structural load rating of the floor or ramp changes. Standard car parks are typically rated for vehicles up to 2 tonne. Weight limit signs must reflect the engineer-certified load rating for each area. Post height restriction signs at entry points and at any overhead obstruction. National Safety Signs supplies weight limit and height restriction signs in multiple sizes for commercial car parks and underground parking structures.

What is the difference between restriction signs and prohibition signs?

Restriction signs and prohibition signs are separate categories under AS/NZS 1319. Restriction signs communicate specific limits — speed, weight, or height — that apply in a designated area. They use a white background with a red circular border, consistent with road sign conventions. Prohibition signs communicate actions that are completely not permitted — no smoking, no entry, no mobile phones — and use a red circle with a diagonal bar over a black symbol on white. Using the wrong sign type for a specific communication is a compliance failure under AS/NZS 1319.

Can I order custom speed restriction signs with my specific limit?

Yes. National Safety Signs supplies speed restriction signs in standard speeds — 5km/h, 10km/h, 15km/h, 20km/h, 25km/h — and custom speeds for specific site requirements. Custom restriction signs can include your site name, additional text such as ‘All Vehicles’ or ‘Heavy Vehicles Only’, or specific zone references. All custom restriction signs comply with AS/NZS 1319 in colour, format, and sizing. Submit custom orders via our online Design a Sign tool or contact our sales team for a quote.
