A rigid truck 12.00 m long is coupled to a drawbar trailer 12.00 m long. The combination length is about 24 m. Is that within the ordinary public-road limit for a combination of vehicles?

1. Yes, because each unit is within 12 m
2. Yes, because combinations may be 24 m by default
3. No, because the ordinary combination (road-train) limit is 18.75 m
4. No, because combinations may not exceed 12 m in total
