Singapore regulations & registration
OneMotoring
OneMotoring is the LTA's online portal for vehicle services in Singapore, including inspection booking, road tax renewal, COE bidding and ownership transfer.
OneMotoring (onemotoring.lta.gov.sg) is the central digital service for Singapore vehicle owners. Drivers book inspection slots, pay road tax, register vehicle modifications, and check inspection results through the portal.
Window tint modifications are not separately registered (unlike some major modifications), but inspection results live in the portal record.
For workshops, knowing the OneMotoring inspection slot timing helps schedule tint installs to coincide with renewal cycles.
