Or a life-saver! Some types of gas lines have left-handed threads, so
you can connect them wrong or take them off by mistake.

Those are great for older vehicles and for things like motorcycles that
have a wet clutch. The newer oils don't work well in those applications
as the additive package cause problems. They won't cause problems in
newer vehicles though.

No, I am not trolling.

Several responses that did answer the question without any sort of smart
remark whatsoever referred to the possibility of left handed threads, that
is why I was asking. I don't want to turn the bolt what seems to be
logically counter-clockwise (i.e., towards the left when facing front or
towards the right when facing rear) and end up snapping off the bolt due to
over torquing it.

For further clarification, replace "left" with driver's side and "right"
with passenger side, as the wrench rotation of "conter-clockwise" will
always be a left rotation.

If you are facing the bolt, counter-clockwise is always counter-clockwise &
clockwise is always clockwise. The usefulness of using left and right to
describe which way to turn a bolt is open to negotiation. "Passenger-side"
is totally irrelevant.
