Which examination assesses a driver's vision at the license office?

The vision examination is specifically designed to assess a driver's eyesight to ensure that they can see adequately to operate a vehicle safely. This examination is an essential component of the licensing process because good vision is crucial for recognizing road signs, hazards, other vehicles, and pedestrians while driving. By evaluating a driver's vision at the license office, authorities can help improve road safety and reduce the risk of accidents related to visual impairments.

The other examinations listed have different purposes: the knowledge examination tests a person's understanding of traffic laws and road signs, the driving exam evaluates practical driving skills behind the wheel, and the practical skills test assesses specific driving maneuvers. None of these examinations focus on assessing the driver's visual acuity directly, which is why the vision examination is the correct answer.
