Which type of vehicle is allowed to tow disabled vehicles for repair on highways with exceptions to size limits?

The correct choice is based on specific regulations regarding the towing of disabled vehicles. Farm equipment is permitted to tow disabled vehicles for repair on highways with exceptions to size limits due to its unique role in agricultural operations. This categorization acknowledges that farm equipment often operates in rural or agricultural settings where larger vehicles may frequently encounter breakdowns, and the size limitations typically imposed on towing are relaxed to accommodate these situations.

Commercial vehicles, passenger cars, and emergency vehicles have different regulations concerning towing. Commercial vehicles typically have stringent size and weight limits when towing, while passenger cars are generally subject to regular towing capacities without special exceptions. Emergency vehicles, while they have certain privileges on the road, are usually engaged in different functions such as responding to incidents rather than regular towing operations for repair.
