Jerem Rot: The Thai Monk's Car Blessing

Also called เจิมรถ, Jerm rot, Car anointing, Yant on the car ceiling

In Thailand a monk blesses a newly bought car by chanting, sprinkling lustral water and drawing a protective yantra in white paste on the ceiling above the driver. A jasmine garland is hung from the mirror for the journey spirit Mae Yanang.

The working

  1. Choose a day. Many Thais pick a date suited to their birth weekday or ask the temple for a good time.
  2. Drive to a temple that blesses cars and present your offerings to the monk with both hands.
  3. Kneel or stand respectfully while the monk chants protective verses in Pali.
  4. The monk draws a yantra of dots and script on the ceiling above the front seats, using white paste or a special pen, and may dab gold leaf or powder on the hood.
  5. Receive a sprinkling of lustral water on the car and on yourself.
  6. Hang a fresh phuang malai from the rear-view mirror as an offering to Mae Yanang, spirit of the vehicle, and replace it before it wilts.
  7. Do not wipe off the ceiling yantra; let it fade on its own.

Take care: Never leave candles or incense burning in or on the car. Keep marks and garlands off the windshield and out of the driver's line of sight. Treat monks with Thai etiquette: women should not touch a monk or hand objects directly to him.

Garlands for Mae Yanang

Thai folk belief · Pre-modern boats to present cars

Long before cars, Thai boat owners honored Mae Yanang, the female guardian of a vessel, with garlands on the bow. Drivers moved the custom to the car, hanging jasmine garlands on the mirror and on taxi dashboards. Garlands are sold at nearly every busy intersection in Bangkok for this reason.

Uses: Jasmine garland

Recorded in: Phuang malai (Wikipedia); Thailex, 'phuang malai'

Lemons under the wheels, Thai style

Thai popular custom with Indian roots · 20th century to present

Thai owners often add a custom shared with India: placing lemons under the tires and driving over them on the first outing. Thai writers describe it as a borrowed belief that blended into local practice from the era of carts and boats to brand-new cars.

Lay blessing at home

Thai household practice · Present

When a monk is not available, some owners do a simple blessing themselves with a white-paste mark, incense and chanting, then visit a temple later. Motorist Thailand notes the rite is not required by law and changes nothing mechanical, but it remains important to many Thai drivers.

Recorded in: Motorist Thailand, 'Bless Your New Car for Good Fortune!'

History

Thai Buddhism has long blended monastic chanting with protective diagrams called yantra (yan or sak yant in Thai), drawn on cloth, metal, skin or buildings. Monks draw them over doorways of new houses, and the car blessing carries the same idea into a new space. The ceiling over the driver is the highest point of the cabin, so the protective script sits above the occupants' heads, a position of respect in Thai custom.

The car rite, called jerem rot, became common as private car ownership grew in the late 20th century. It blends Buddhist chanting and lustral water with older spirit beliefs such as Mae Yanang, the guardian spirit of boats and vehicles. Taxi drivers in Bangkok often keep small altars on the dash with garlands, amulets and Buddha images. In January 2026 a candle left burning during a blessing set a car's front end on fire in Phetchabun, a reminder to keep flames outside.
