New car buyers using dealers' red licence plates will have 60 days to register their vehicles with land transport authorities or face arrest and a fine, starting on Oct 1 and continuing until Dec 31 this year.
From Jan 1 onwards, they will have 30 days to properly register their vehicles, Department of Land Transport chief Sanit Promwong said on Tuesday. Fines would range from 1,000 baht to 10,000 baht.
The department and the police would jointly supervise the regulation.
The two agencies would arrest owners of private vehicles using red licence plates on the roads outside the allowed period, and fine them.
People buying new cars between Oct 1 and Dec 31 this year must have their vehicles registered at a DLT office within 60 days from the date they receive their vehicles.
Those who purchase new vehicles from Jan 1 onwards must register them within 30 days, said Mr Sanit.
Owners caught failing to do so would be caught and fined on the spot.
