Tanker Practice Question 27

NTanker · Question 27

A loaded tanker that begins to skid in a curve should:

• ASteer harder into the turn
• BReduce throttle and steer to maintain directional control without abrupt input
• CBrake hard immediately
• DUse the trailer hand valve hard

Correct answer: B. Reduce throttle and steer to maintain directional control without abrupt input

Why: Smooth inputs are essential. Hard braking or steering in a skid often pitches the load and triggers rollover.

Study technique for this topic

Know the difference between baffled, unbaffled, and compartmented tanks, the safe outage percentage for liquid expansion, and why front-to-back surge is more dangerous than side-to-side surge.
