The National Medical Standards (private or commercial) and the guidelines Assessing Fitness to Drive are used to assess whether an employee has a mental or physical incapacity (a medical condition) that is likely to affect an employee’s ability to drive a motor vehicle safely. The doctors at Our GP Complex are familiar with the medical standards used to assess drivers for fitness to drive commercial vehicles. Our doctors provide advice, based on the standards, about how an employee’s particular health condition might affect their ability to drive safely and how it might be managed.
