What document must you present to obtain a Class 3 license?

To obtain a Class 3 license, presenting a valid driver's abstract is essential as it reflects your driving history and any accumulated demerits. This document allows the licensing authority to assess your qualifications and determine if you meet the necessary criteria for holding a Class 3 license, which permits the operation of larger vehicles like trucks and buses.

In the context of the other options, while a birth certificate is important for identity verification, it does not provide relevant information about driving history. Proof of insurance is typically required to operate a vehicle but is not necessary for the licensing process itself. A medical report may be required in certain situations, particularly if there are health concerns that could affect driving ability, but it does not universally apply to everyone seeking a Class 3 license. Therefore, the driver's abstract is the key document that demonstrates your eligibility and safe driving record for being granted a Class 3 license.
