Why should a driver be aware that some states impose lower maximum speed limits specifically for doubles or triples combinations?

Pick an answer

1. Their handling characteristics can make higher speeds riskier than for a single trailer, prompting some jurisdictions to set lower limits

3. Speed limit differences apply only to triples, never to doubles
4. Lower speed limits for doubles and triples exist only as a historical formality with no real safety basis behind them left over from decades-old regulations
