How many driver's licenses can be used for demerit points on one vehicle

[VanLilah]

A vehicle can only use three different driver's licenses for demerit points, and the license holder must personally present the license for point deduction. Here is relevant information: Scoring cycle: If a motor vehicle driver's demerit points do not reach 12 within a scoring cycle and all fines have been paid, the points will be cleared; if the points do not reach 12 but there are unpaid fines, the points will carry over to the next scoring cycle. If 12 points are deducted within one scoring cycle, the driver must pass the subject one test after studying at the issuing vehicle management office or the local traffic violation office to clear the full-point record and restore normal use of the driver's license.
