Question 32 of 120

Before a trip pulling triples, why should you check whether your route allows them?

Pick an answer

Only bridges need to be checked, not general route legality
Triples are allowed everywhere doubles are allowed, so no separate route check is ever needed no matter which highway you take
Not every state or road permits triple trailers, so a route allowed in one place may be illegal in another
Route legality only matters for hazardous materials loads

Correct!

Not quite. The correct answer is highlighted.

Show answer

Correct answer to question 32 (Doubles/Triples): Not every state or road permits triple trailers, so a route allowed in one place may be illegal in another

Why

Triple-trailer combinations are not permitted on every highway or in every state, so confirming the route allows them before the trip avoids an illegal or unsafe situation partway through.
