What is a key requirement for insulin-controlled drivers to qualify for a diabetes exemption?

The key requirement for insulin-controlled drivers to qualify for a diabetes exemption is that they must have adequate blood glucose monitoring. This stipulation is critical because managing diabetes effectively involves continuous monitoring of blood glucose levels to prevent hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), which can impair driving ability. Regular and accurate monitoring not only helps the individual understand their blood sugar patterns but also ensures they can take appropriate action if their levels fall outside the normal range.

This requirement supports safety on the road and is essential for making informed decisions about driving, especially since insulin users are at a higher risk for sudden changes in their condition. The other options, while they may relate to aspects of diabetes care, do not directly address the essential requirement of monitoring that is crucial for safe driving and obtaining an exemption.
