When a trailer on dual tires is hauling a placarded hazardous load, at what times must its tires be inspected?

Correct answer: Before setting out and again at each stop.

Answer options

  1. ABefore setting out and again at each stop Correct
  2. BEvery 200 miles, whether or not you stop
  3. COnly after the load has been delivered

Why

With a placarded load riding on dual tires, each tire has to be examined before departure and again at every stop, since an underinflated tire can overheat and catch fire. Finding a soft or hot tire early keeps a small problem from becoming an emergency.
