2023 California Code › Vehicle Code - VEH › DIVISION 14 - TRANSPORTATION OF EXPLOSIVES › Section 31614.

31614. The following provisions shall apply to any vehicle transporting explosives subject to this division:
(a) When transporting explosives through or into a city or any other congested area for which a route has not been designated by the Department of the California Highway Patrol, drivers shall follow such routes as may be prescribed or established by local authorities.
(b) Where routes are not prescribed by local authority, every driver of a vehicle transporting explosives shall avoid, so far as practicable, and, where feasible, by prearrangement of routes, driving into or through congested thoroughfares, places where crowds are assembled, streetcar tracks, tunnels, viaducts, and dangerous crossings.
(c) No driver or other person in charge of any vehicle on any public or private property shall permit any explosive to be loaded into, or on, or to be unloaded from any motor vehicle with the engine running, and, whenever any loading operation is in progress, the parking brake on the motor vehicle shall be securely set and all reasonable precautions taken to prevent movement of the motor vehicle during loading or unloading.
(d) No driver or other person in charge of such vehicle shall operate or permit the operation of any vehicle transporting explosives unless all of that portion of the lading which consists of explosives is contained entirely within the body of the motor vehicle or within the horizontal outline thereof, without overhang or projection of any part of the load, and if such motor vehicle has a tailboard or tailgate it shall be closed and secured in place during such transportation.
(e) Every motor vehicle transporting explosives shall have either a closed body or have the explosive cargo covered with a fire- and water-resistant tarpaulin, and in either event, care shall be taken to protect the load from moisture and sparks. Subject to other exceptions as are permitted by the United States Department of Transportation regulations, explosives may be transported on flat-bed vehicles if the explosive portion of the load on each vehicle is packed in fire- and water-resistant containers or covered with a fire- and water-resistant tarpaulin.
(f) No person shall operate any vehicle transporting explosives past any fire of any kind burning on or near the highway until the driver ascertains that such passing can be made with safety.
(g) No motor vehicle transporting explosives shall be left unattended upon any street or highway except in extreme emergency. The vehicle shall be deemed attended whenever a driver or person in charge thereof is in or upon the vehicle or is in a position to observe the vehicle at all times. The driver or person in charge of a vehicle transporting explosives may, however, leave the vehicle unattended at any place designated as a safe parking place on the list of safe stopping places prepared by the Department of the California Highway Patrol unless conditions exist, which are known to the driver, which make it unreasonable to do so.
(h) No driver or other person shall smoke or light any match or otherwise have or produce any fire or flame while in, upon, or near any vehicle transporting explosives.
(i) No person shall transport any explosives in a passenger vehicle, or bus, which is subject to this division.
