Why do loads of temperature-sensitive cargo need extra attention to stops and shade in extreme heat?
- A.Heat buildup in a parked trailer can damage cargo and, for some loads, create safety hazards, so plan stops, ventilation or refrigeration checks, and parking with heat in mind
- B.Trailer interiors stay cool in summer
- C.Only winter affects cargo temperature
- D.Shade has no effect on trailer heat
Correct answer
A. Heat buildup in a parked trailer can damage cargo and, for some loads, create safety hazards, so plan stops, ventilation or refrigeration checks, and parking with heat in mind
Why
A closed trailer in summer sun works like an oven, and reefer units, vents, and seals must be verified at stops, not assumed. Protecting the load in heat is part of the driver's en route inspection duty.
