High and wide loads

Transporting an oversized load can be dangerous. Depending on the situation, we may need to move, raise or shield powerlines, provide a road escort or even temporarily switch off power to keep everybody safe.

If you need to transport an oversized load across the Horizon Power network, you must apply for a high load permit to ensure safety precautions are observed in proximity to powerlines. This applies to loads higher than 4.3 metres (4.6 metres for livestock vehicles travelling on nominated routes) or wider than 5.5 metres

Transport operators must refer to Main Roads Western Australia before applying for a high load permit with Horizon Power. Note: it is a requirement of any Main Roads permit to also obtain a high load permit from Horizon Power.
