The requirements for separate cards for a motorcycle license and a driver's license vary depending on the jurisdiction you are in. In some places, you may receive a single card that indicates you are licensed to operate both a motorcycle and a regular motor vehicle. This card may have specific endorsements or designations indicating that you are qualified to ride a motorcycle.
In such cases, you would need to carry both cards with you when operating a motorcycle or a regular motor vehicle.
To obtain accurate information regarding your specific location, I recommend checking with the relevant local licensing authority or department of motor vehicles (DMV) in your area. They can provide you with the specific regulations and requirements regarding motorcycle and driver's licenses, including whether you need separate cards or not.
