At Roadhire, safety and compliance are at the heart of every project we support. When it comes to protecting road users and workers, not all barriers are created equal. That's why MASH-rated barriers are the industry standard — providing reliable, tested, and approved safety performance.
What is MASH?
MASH (Manual for Assessing Safety Hardware) is the internationally recognised standard for testing roadside safety devices. It ensures that barriers, crash cushions, and other safety hardware meet strict performance requirements under real-world crash conditions.
Understanding TL Ratings
MASH uses Test Levels (TL) to classify how barriers perform in different speed and impact scenarios.
- TL3 Rating
- Designed for use on roads with traffic speeds up to 100 km/h.
- Tested with small passenger vehicles and pickup trucks.
- Provides reliable protection for urban roads, highways, and medium-speed work zones.
- TL4 Rating
- Suitable for higher-speed roads and more demanding conditions.
- Tested with larger vehicles, including single-unit trucks.
- Provides greater containment and redirection, making it ideal for motorways and high-risk environments.
Why TL3 & TL4 Matter for Your Project
- Proven Safety – You know the barrier will perform effectively under impact.
- Regulatory Compliance – Meets Austroads and state road authority requirements.
- Reduced Risk – Protects workers, motorists, and equipment from serious harm.
- Peace of Mind – Confidence that your project meets the highest safety standards.
