Why doesn't this stop cars from moving?

[MWhiteNC4]

This code runs when the cars health is set to 0, the code definitely runs but it doesn't stop the car from moving.

ent:StartEngine(false);
ent:EnableEngine(false);

do you have a check if the engine should be turned off or not running if StartEngine and EnableEngine is set to false?
