California Insurance Code
For the effective discharge of such duties, an underwriter's corps may enter any burning building or any building in which property is burning, or any building such corps or any officer thereof deems to be immediately exposed to an existing fire or in danger of taking fire from a burning building, and may remove or otherwise protect any property from fire or damage by water during and immediately after such fire.
Such corporation, with its officers and corps, when going to a fire with its equipment, has the same right of way as the regular fire department of the municipality in which such corporation is operating, except as to such fire department.
All ordinances passed by the municipal authorities of any city or town wherein such a corporation carries on business, and all laws of this State applicable to such municipality which provide for the punishment of any person or persons wilfully or carelessly obstructing the progress of the apparatus of the fire department of such municipality while going to a fire, or of any person or persons wilfully or carelessly injuring any animal or property of said fire department, shall likewise apply to such corporation to the same extent as to such fire department. Such laws and ordinances and their penalties, may be enforced in the same courts and in the same manner, and with equal force and effect in the case of such corporation as in the case of the fire department.
