This safety sign is installed in front of a bridge. What does it mean?
💡 Hint
Regulatory signs with a number are told apart by the unit (t or m) and the direction of any arrows (Annex 6 Nos. 220 to 223 of the Enforcement Rule). The same number means weight, height, width or distance depending on the unit, so read the unit first.
Answer: ①
Explanation
This sign, with 't' (tons) next to the number, restricts vehicles exceeding the weight shown (Enforcement Rule Annex 6, No. 220). A height limit is shown with up-and-down arrows and 'm', a width limit with left-and-right arrows and 'm', and the following-distance sign shows two cars and 'm'.
