How are the dangerous goods being transported on Ontario roads identified?
- By the driver's behavior
- By the color of the containers
- By the size of the vehicle
- By markings and safety labels corresponding to each category of dangerous goods ✓
Answer: D. By markings and safety labels corresponding to each category of dangerous goods
Dangerous goods are identified by markings and safety labels that correspond to each category of dangerous goods.
Why this is the answer
The truck handbook says that when dangerous goods are being transported, safety marks, placards or labels show their classification and the type of danger they present. Those marks are intended to provide a quick identification and can appear on trucks, cargo and pallets. That supports identifying dangerous goods through markings and safety labels tied to each category, rather than through the driver, container colour or vehicle size.
Why the other answers are wrong
- A. By the driver's behavior — A driver's behaviour does not identify the goods being carried; the handbook points to safety marks and labels instead.
- B. By the color of the containers — Container colour is not described as the identifier; the required identification is through safety marks, placards or labels.
- C. By the size of the vehicle — Vehicle size is not used for this; the marks can be found on trucks, cargo and pallets and show the dangerous-goods class.
Remember it
Think of a placard or label as the load's name tag.
