We had the annual blessing of automobiles, which occurs on the Sunday closest to the feast of the Prophet Elias (who ascended as if into heaven in a fiery chariot).

Prayer for the Blessing of Automobiles

O Lord our God, Who makes the clouds Thy chariot and Who walks on the wings of the wind, Who has sent to Thy servant, the Prophet Elias, a chariot of fire, Who has guided man to invent this (car, truck, motorcycle, etc.) which is as fast as the wind. We thank Thee for Thou hast provided Thy servants with this vehicle to serve their various needs.

Therefore, O Master, pour out now upon it Thy heavenly blessings; assign to it a guardian angel to preserve it from all evil. And as Thou didst grant faith and grace by Thy deacon Philip to the man from Ethiopia who was sitting in his chariot and reading holy Scripture, show the way of salvation to Thy servants. So that helped by Thy grace and always intent on doing good works, they may after all the trials of their pilgrimage on earth, attain to everlasting joys, through the intercessions of our Most-pure Lady, the Theotokos and Ever-Virgin Mary, by the power of the precious and life-giving Cross; through the prayers of the holy Angels; of St. Nicholas the Wonderworker and of all the Saints:

For Thou art the Provider and Sanctifier of all things and to Thee do we ascribe glory, and to Thy Only-begotten Son, and Thy All-holy, good, and life-creating Spirit, now and ever and unto ages of ages. Amen.
