No, you cannot do a Code 14 with a Code 10 learner’s license in South Africa. In order to apply for a Code 14 learner’s license, you must already hold a valid Code 10 driver’s license and meet the other requirements for the Code 14 license, such as being at least 18 years old, passing a medical examination, and passing a learner’s license test.
The Code 14 license is a heavy-duty driver’s license that allows you to operate heavy goods vehicles (HGVs) with a gross vehicle mass (GVM) of 16,000 kg or more. It requires additional training, knowledge, and skills beyond what is required for a Code 10 license.
If you have a Code 10 learner’s license, you can apply for a Code 10 driver’s license after passing the required tests and meeting the other requirements. Once you have a Code 10 driver’s license, you can then apply for a Code 14 learner’s license if you meet the additional requirements.
