A driver is carrying 10 litres of a Transport Category 1 substance, 100 litres of a Transport Category 2 substance, and 300 litres of a Transport Category 3 substance. Does this load qualify for the small load exemption?

1. Yes, because the total volume of liquid (410 litres) is well below the 1000-litre limit
2. Yes, because the calculated point total is exactly 900 points
3. No, because the calculated point total is 1100 points, which exceeds the 1000-point limit
4. No, because Category 1 and Category 2 substances cannot be mixed under this exemption
