Goods vehicle operators are facing a 25 per cent hike in the price of the discs they have to display on their vehicles.
When Tynwald sits on Tuesday, it'll consider new regulations from the Department of Environment, Food and Agriculture governing road transport fees.
The cost of operator's discs for goods vehicles is set to rise from £60 to £75, while passenger cars or minibus prices will rise from £118 to £125.
Ply for hire plates for taxis, meanwhile, face a rise of more than eight per cent - from £35 to £38 per district.
