What is the time limit for using a residence certificate when applying for a Thai driving license?

The question discusses whether the Department of Land Transport (DLT) in Thailand accepts residence certificates that are one or two weeks old for applying for a driving license, and how many certificates are needed for both car and motorbike licenses. Comments indicate that a residence certificate is generally valid for 30 days, and that separate certificates may be needed for a bank account and driver's license. It was also noted that the DLT may accept an original certificate along with a photocopy when applying for both licenses simultaneously.
