Show answer

Correct answer to question 14 (Doubles/Triples): The combination will need more distance and a lower merging speed to safely match traffic

Why

A doubles combination is heavier and slower to build speed than a single trailer, so it needs a longer ramp distance and more care matching the speed of highway traffic.
