A.55 mph(Correct)
B.70 mph
C.60 mph
D.65 mph

Explanation

The maximum legal speed limit for triple trailer combinations in Nebraska on interstate highways is 55 mph, regardless of posted higher limits for other vehicles. This is a specific regulation to ensure safety with such large and complex vehicles.

Question 2Railroad Crossings

You are approaching a railroad crossing with a triple trailer combination. The distance from the front of your first trailer to the rear of your last trailer is 105 feet. The crossing signals are flashing, but the gate is not yet down. How much clearance should you ensure is available before proceeding across the tracks?

A.At least 75 feet
B.At least 100 feet(Correct)
C.At least 50 feet
D.At least 120 feet

Explanation

For any combination vehicle, especially triples, you need to ensure the entire combination, plus a buffer zone, can clear the tracks. A common rule of thumb is to have at least 100 feet of clearance, ensuring the entire 105-foot combination plus some margin can fit comfortably.

Question 3Lane Changes and Tracking

When performing a lane change with a triple trailer combination, what is the primary concern regarding the rear trailers?

A.The rear trailers are less susceptible to wind than single trailers.
B.The rear trailers may cut into the path of the original lane.(Correct)
C.The rear trailers will naturally widen the turn radius.
D.The rear trailers will track directly behind the tractor.

Explanation

The most significant hazard with multi-trailer combinations is trailer sway and the tendency of rear trailers to track inside the path of the preceding unit. When changing lanes, the rear trailers can cut into the space you just vacated, potentially causing a collision.
