The chief engineer of the state department of transportation shall upon proper application and at no charge issue a special permit to any person allowing the movement on state and federal highways of farm products between sunset and sunrise not in excess of fourteen feet in width. Special permits allowing movement of oversize loads of farm products shall allow for movement between sunset and sunrise, subject to appropriate requirements for safety lighting on the load, appropriate limits on load dimensions and appropriate consideration of high traffic density between sunset and sunrise on the route to be traveled. The chief engineer may also issue upon proper application a special permit to any person allowing the movement on the state and federal highways of concrete pump trucks or well-drillers equipment.
