A vehicle traveling control method includes detecting a remaining fuel amount in a fuel tank including a fuel chamber in which a suction port of a fuel pump is disposed for sucking fuel to be supplied to an engine, the fuel tank being configured to generate negative pressure for sucking fuel to the fuel chamber by ejecting a part of fuel sucked by the fuel pump into the fuel chamber via a fuel line, permitting, when a predetermined condition is satisfied, inertial traveling during which a vehicle travels, with the engine kept stopped, operating, when the detected remaining fuel amount is less than a first threshold, the fuel pump despite the engine stopped owing to the inertial traveling, and prohibiting stop of the engine when the detected remaining fuel amount is less than a second threshold smaller than the first threshold.
