What does the following safety sign mean?
💡 Hint
A regulatory sign with a red circular border and a diagonal line across the symbol prohibits the vehicle shown in the symbol (Annex 6 of the Enforcement Rule). The target depends on the shape drawn, such as a cargo bed, a bus or a flame, or on a unit like 't' next to a number, so match the symbol to the vehicle type.
Answer: ④
Explanation
This sign shows a truck with a cargo bed crossed out and prohibits trucks (Enforcement Rule Annex 6, No. 203). If needed, a supplementary sign shows the section, period, reason, gross vehicle weight and body length. A bus symbol means buses, a flame symbol means vehicles carrying hazardous materials, and a number with 't' means a weight limit.
