Tom Elliott says the pay per kilometre road tax system being floated for Victoria has trouble written all over it.

He says there are a stack of issues that would present themselves if it happened.

Victorian drivers face paying a distanced-based charge, instead of fuel excise and other taxes, under a major overhaul of road-funding.

The plan has been backed by the Victorian government.

The Andrews government has already set a 2.5 cents per kilometre charge for electric vehicles.

“This has got stuff up written all over it,” Tom Elliott said on Friday.

“It might be a good idea, in theory, but it’s got stuff up written all over it.”
