Which vehicle may not travel on a road section where this safety sign is installed?
💡 Hint
The no-entry sign for vehicles carrying dangerous goods decides its target by whether the load is dangerous goods, not by the type of vehicle (Annex 6 No. 231 of the Enforcement Rule). Merely carrying cargo does not make a vehicle subject to it, so check whether the load is dangerous goods such as explosives or gas.
Answer: ①
Explanation
This sign, flames above a car, prohibits vehicles carrying hazardous materials (Enforcement Rule Annex 6, No. 231). These are motor vehicles transporting the hazardous materials listed in Annex 9 of the Enforcement Rule, and a tank truck carrying liquefied petroleum gas is one of them. An empty bus or vehicles carrying moving or travel luggage are not covered.
