The High Vehicles (MMS-ADV-14) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to alert drivers of oversized or tall vehicles to potential clearance restrictions ahead. Commonly used near bridges, tunnels, overpasses, or temporary works with height limitations, this sign provides clear early warning to reduce the risk of accidents or damage. Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates directly with the state’s approved multi-message frame system.
As part of Western Australia’s modular multi-message system, the High Vehicles panel can be displayed independently or paired with complementary warnings such as “Detour Ahead” or “Use Other Route” to form one clear, compliant display. The approved frame supports multiple configurations—two 600 × 600 millimetre panels above a 1200 × 300 millimetre panel, or one 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This modular flexibility ensures councils, contractors, and traffic management providers can adapt signage quickly as conditions change.
Manufactured with CL400 Class 1W reflective material in traffic yellow, the High Vehicles panel ensures strong visibility in daylight, at night, and in poor weather. Its durable, weather-resistant construction complies with Australian traffic sign standards, providing long-lasting reliability in demanding environments. By warning of potential clearance hazards, the sign enhances road safety for heavy transport and reduces risk to infrastructure.
For freight routes, roadworks near bridges or overhead structures, and detours with restricted clearance, the High Vehicles (MMS-ADV-14) sign delivers trusted compliance, high-visibility performance, and dependable durability in one modular panel.
