A county wheel tax ordinance is on this week’s Mercer County Board agenda. The measure calls for a $15 fee for cars, motorcycles and recreational trailers. A $20 fee for trucks (plates B-Z), farm trailers and a business permanent plate. And a $30 fee for trailers/trucks (plates TA-to-TN) and farm trucks (plates VF-VZ). Money collected from the county wheel tax will be deposited in a special highway fund and the revenue shall be used for highway and bridge maintenance and construction. Penalty for non-compliance is listed at between $30 and $150. The item is on Tuesday night’s agenda.
