Planning and practical challenges undertaken by oversized / overmass vehicles on WA roads

Peter Lewis has been with the Main Roads Dept for over 12 years and is now the Heavy Vehicle Technical Officer . His presentation will provide an overview of Heavy Vehicles and oversize movements . Road transport makes a vital contribution to Western Australia's economy .  Due to the State's remote and rugged nature , there is often no alternative but to move very large items by road .  Vehicles carrying over sized and over mass ( OSOM ) loads come in a wide variety of shapes and sizes , typically moving much more slowly than ordinary traffic and taking up a greater proportion of road than other vehicles . The movement of OSOM loads by road is strictly regulated to ensure safety for all road users .
