Exempt a vehicle towing farm machinery from vehicle size limits

HB 672 exempts vehicles towing farm machinery from standard vehicle size limits on public roads in Ohio. It directly affects farmers and agricultural transporters who move equipment like tractors or harvesters. The bill adds two conditions for this exemption: the towing vehicle must meet size limits without the machinery, or the operator must hold permits covering the combined dimensions. This change simplifies transporting large farm equipment without requiring special permits for routine movements.
