It shall be the duty of the permittee to make certain that the security of the traveling
public is safeguarded and its rights are not unreasonably curtailed. Unless specifically
indicated in the permit or authorized by the Superintendent of Highways, the travel
path shall not be obstructed. The portions of the highway which are torn up or which
are used for storing materials, or are otherwise unsafe for public travel, shall be
adequately protected at all times to avoid the possibility of accidents. Such areas
shall be marked at night by flares, lanterns, lights, flasher beacons or other warning
devices approved by the Superintendent of Highways. When portions of the traveled
way are made dangerous for the movement of vehicles or pedestrians, a sufficient number
of Police Officers, flagmen or trafficmen shall be employed by the permittee to direct
the traffic safely through the areas. The work shall, if possible, be planned to avoid
such conditions.
