What is the driving experience after merging D license with C1?

[DelJudah]

The driving experience is calculated from the date when the first driver's license was obtained. For example, if you first obtained a C1 driver's license and later acquired a D license through an additional driving test, then the driving experience is calculated based on the C1 license. If you first obtained a D license and later added a C1 license, then the driving experience is calculated based on the date of obtaining the D license. In other words, the driving experience is calculated based on the date of whichever type of driver's license was obtained first. C1 Driver's License: The C1 driver's license is one of the codes for motor vehicle driver's licenses. The C1 license allows driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light, small, and micro special-purpose vehicles; small passenger vehicles with a seating capacity of 9 or fewer people. Age Requirements: The minimum age requirement for a C1 driver's license is 18 years old, with no upper age limit. However, applicants aged 70 and above must pass tests on memory, judgment, and reaction abilities.
