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
- AOnly when the vehicle is hauling explosives
- BOnly when the vehicle has a fire sprinkler system
- 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.
