A driver is transporting Class 3 flammable liquids. What parking restrictions apply?

HAZMAT PARKING RESTRICTIONS protect the public by ensuring that vehicles carrying dangerous cargo are not left unattended in populated areas where a leak or fire could cause mass casualties. GENERAL HAZMAT PARKING RULES: (1) AVOID POPULATED AREAS: Never park within 300 feet of a bridge, tunnel, dwelling, or place of business unless necessary for delivery or receiving; this limitation is especially strict for Division 1.1/1.2/1.3 (most dangerous explosives), poison gases (Division 2.3), and poison liquids (Class 6.1, Packing Group I); (2) FLAMMABLES SPECIFICALLY: Keep away from open flames and sparks; minimize time parked near populated areas; (3) ATTENDED VEHICLES: Vehicles carrying certain Class 1 (explosives) and Division 2.3 (poison gas) materials in certain quantities must be attended at all times (driver within 100 feet and capable of moving the vehicle); (4) UNATTENDED PARKING: When parking a hazmat vehicle and leaving it unattended, the parking brake must be set and all doors should be locked; (5) REST AREA PARKING: Use of rest areas for hazmat vehicles is technically not prohibited but drivers should minimize time and ideally use truck stops where security and facilities are available; (6) FUELING: Must be attended when fueling — engine off, no smoking, remain present throughout. PERMIT-REQUIRED ROUTES: Class 1.1/1.2/1.3 explosives require pre-approved routes; driver must follow those routes even if GPS suggests alternatives.
