What kind of running means walking?

Riddle: What kind of running means walking?

Answer: Running out of gas!

Hint: Think of a car that suddenly stops.

Why this answer works
When a vehicle is “running out of gas,” it soon can’t drive—so you end up walking instead. The “running” here means “depleting,” not moving fast.

Fun fact
Before fuel gauges were common, drivers used dipsticks or sight glasses to check fuel levels—making “running out” far more frequent.
