If towing something behind your vehicle, the drawbar or towing connection:

  1. Must exceed 15 feet in length.
  2. Must be strong enough to pull all the towed weight. ✓
  3. May not have any flags or reflectors attached to it.
  4. Must be marked with a yellow flag.

Answer: B. Must be strong enough to pull all the towed weight.

The drawbar or towing connection must be strong enough to pull all the towed weight.

Why this is the answer

The handbook lists three requirements for a drawbar or towing connection, and the first one is that it be strong enough to pull all the towed weight. Length is limited rather than required, and the flag rule applies only to chain, rope, or cable connections, where a white flag of at least 12 inches square is needed. So the strength of the connection is the requirement that matches the question.

Why the other answers are wrong

Remember it

Picture the connection holding the whole load: strength first, then length limits, then the white flag for chain, rope, or cable.
