National Registry of Certified Medical Examiners (NRCME) DOT Practice Exam

What is the recommended action if a driver fails a vision test?

1. Certify the driver for 2 years.

2. Require additional testing.

3. Disqualify the driver.

4. Refer to an ophthalmologist.

The correct answer is: Disqualify the driver.

When a driver fails a vision test, the appropriate action involves disqualifying the driver from operating a commercial vehicle until they meet the necessary vision standards. This is essential for maintaining safety on the roads, as adequate vision is crucial for the safe operation of large vehicles. Disqualification ensures that only those with the required level of visual acuity can perform safety-sensitive functions. Such measures help prevent potential accidents caused by impaired vision, thus protecting both the driver and other road users. While other options may seem valid, they either do not provide the immediate necessary action in response to a failing vision test or could lead to unsafe conditions. For example, additional testing could lead to delay, and certifying a driver without the required vision could result in dangerous situations. Referring to an ophthalmologist is a reasonable step for further evaluation and treatment, but it does not address the immediate concern of ensuring driver safety by preventing them from operating a vehicle until their vision meets the required standards. Therefore, disqualifying the driver is the most effective and responsible course of action.
