Truck marker signs play a critical role in road safety, traffic control, and infrastructure protection—especially in areas that support freight, mining, and industrial transport. Choosing the right truck markers helps ensure compliance with transport laws and provides clear visual guidance for heavy vehicle drivers navigating restricted areas or approved routes.
Whether you’re a local council, mine site operator, or industrial developer, this guide will walk you through the key considerations for selecting the correct truck marker signage for your site.
🚛 Common Types of Truck Markers
Truck markers are designed to clearly indicate approved vehicle access, loading limits, and route restrictions. In Western Australia and across the country, common truck signage types include:
- T1 and T2 Markers: Used to indicate truck routes based on axle load limits and road classifications.
- B-Double Route Markers: Inform drivers of approved B-double truck access along designated freight corridors.
- Road Train Access Signs: Crucial in regional and outback areas, these designate which vehicles can use long-distance highways and remote industrial roads.
- Load Limit Signs: These specify maximum allowable weights for bridges, culverts, or weak road surfaces.
- Height & Width Clearance Markers: Essential near tunnels, low bridges, or tight roadways.
Selecting the correct sign depends on the type of trucks expected and whether the road is local, regional, or state-managed.
🌦 Material Durability & Compliance Standards
Heavy vehicle signage must stand up to the elements—especially in high-traffic corridors or exposed environments like mine access roads, coastal highways, or remote outback sites.
When choosing truck markers, consider:
- Reflective Finishes: Ensure visibility during night and poor weather. Class 1 reflective sheeting is often recommended for maximum visibility.
- Weather-Resistant Materials: Aluminium or galvanised steel signs with UV-stable coating help signs last longer under Australian sun, salt spray, and dust exposure.
- Edge Protection & Anti-Graffiti Coatings: For urban industrial zones, protective coatings extend sign life and reduce maintenance.
All truck markers supplied by Civil Products WA are compliant with AS 1742 and Main Roads WA standards—ensuring your site or road upgrade meets the legal requirements for signage.
📍 Placement Considerations for Industrial & Freight Zones
Incorrect or poorly placed truck signage can lead to driver confusion, increased risk of accidents, and damage to infrastructure. Here’s what to factor into your placement plan:
- Approach Visibility: Position signs well in advance of turnoffs or restricted zones, allowing drivers time to respond.
- Height & Line of Sight: Mount at appropriate heights to ensure visibility from heavy vehicles’ perspective.
- Consistent Placement: Use consistent spacing and alignment to prevent misinterpretation—especially along designated freight corridors.
- Site-Specific Hazards: For mining or construction access points, signage may need to be reinforced or mounted on heavy-duty posts to withstand vehicle impact or harsh conditions.
