A lighter that does not contain unabsorbed fuel is allowed to be carried on one's person?

• A. Not allowed
• B. Yes
• C. Only in checked baggage
• D. Only if empty

Answer: (B)

The key idea is safety of flame-producing devices in the cabin. Lighters pose a fire risk mainly because of the fuel inside them. If a lighter has no unabsorbed fuel left, there’s nothing flammable inside that could vaporize and ignite. That condition allows it to be carried on your person in many cabin rules, even though fully fueled lighters are prohibited in carry-on baggage.

So, a lighter that does not contain unabsorbed fuel is allowed to be carried on your person. It doesn’t have to be completely empty in every sense, just fuel-free in terms of vapors that could ignite. The other options don’t fit because the lighter can be carried in-cabin on your person when empty of fuel, it is not restricted to checked baggage, and it isn’t required to be completely empty beyond lacking unabsorbed fuel.
