However, the problem is that in some areas, after obtaining an electronic license, updating your license information will reset your license's start date. Then, to obtain a Class C license, you need to hold it for 18 months. If you update your license during this 18-month period, congratulations, your 18 months will restart.
If the local authorities can provide proof that you have been registered for at least 18 months, that would be great. However, I've heard reports that some areas simply don't have a way to issue such proof, which is just a matter of passing the buck (or kicking the can down the road).
