Sample CDL Doubles & Triples practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

Question 1Speed Limits

When driving a triples combination, what is the maximum legal speed limit on Indiana highways, assuming no other posted speed limits apply?

A.60 mph
B.55 mph(Correct)
C.50 mph
D.65 mph

Explanation

In Indiana, the maximum legal speed limit for a triples combination is 55 mph on highways, which is lower than the standard speed limit for most other vehicles due to the increased complexity and braking distance required.

Question 2Weight Limits

You are transporting 40,000 pounds of general freight in a doubles combination. If your tractor is rated for 40,000 pounds GCW and your trailers are rated for 30,000 pounds GCW each, what is your maximum legal Gross Combination Weight (GCW) in Indiana if you are not exceeding any individual component limits?

A.100,000 pounds
B.90,000 pounds
C.70,000 pounds
D.80,000 pounds(Correct)

Explanation

The maximum legal GCW for most commercial vehicles in Indiana is 80,000 pounds. While the load is 40,000 lbs, and the tractor and trailers have ratings, the overall GCW is capped by federal and state regulations, typically at 80,000 lbs, unless specific permits or routes allow for higher weights.

Question 3Vehicle Dynamics

When performing a 'crack the whip' maneuver during a lane change with triples, what is the primary hazard you are trying to mitigate?

A.The rear trailer overturning(Correct)
B.The lead trailer jackknifing
C.The tractor losing steering control
D.The middle trailer losing traction

Explanation

The 'crack the whip' effect is most pronounced at the rear of a long combination vehicle. The rear trailer is most susceptible to overturning due to the centrifugal forces exerted on it during a sharp turn or lane change.
