When is it acceptable to drive a placarded vehicle close to an open fire?

Correct answer: Only when you can get safely past it without stopping.

Answer options

  1. AOnly when the vehicle is hauling explosives
  2. BOnly when the vehicle has a fire sprinkler system
  3. COnly when you can get safely past it without stopping Correct

Why

A fire near hazardous cargo could set off an explosion or a release, so a placarded vehicle may go near an open fire only if it can get by safely without stopping. Carrying explosives makes a fire more dangerous, not less, and no onboard equipment creates an exception.
