Which statements about blind-side jackknife backing should be followed for safety?

• A. It should never be attempted without a spotter.
• B. You should frequently stop to check clearance.
• C. Ending with more than a 90-degree angle is recommended.
• D. Both A and B.

Answer: (D)

Backing a tractor-trailer in blind-side situations relies on two safety practices. First, use a spotter who can see what you can’t from the cab and guide you with clear signals to keep the trailer away from obstacles. Second, stop frequently to check clearance because your view is blocked and small misjudgments can quickly become serious hazards. The idea of ending with a wide, more-than-90-degree trailer angle isn’t a safe practice, as sharp angles increase the risk of jackknifing or striking objects. So the safest approach is to have a spotter and pause to verify clearance throughout the backing maneuver.
