Am I required to pay Zakat on a car that is owned by me, if I use it to deliver food?

الجواب حامدا و مصلیا

Zakat is not due on the value of a car that is used for one’s personal use or for one’s livelihood. This is why Zakat is not due on the value of the car that the questioner is using for delivering food.
And Allah knows best.
