Which of the following is a recommended step for drivers with coronary heart disease?

Seeking clearance from a cardiovascular specialist is critical for drivers with coronary heart disease. This recommendation emphasizes the importance of medical oversight in managing a condition that can significantly impact a driver’s health and safety on the road. A cardiovascular specialist can conduct a thorough evaluation, provide personalized treatment plans, and assess the driver's readiness to return to driving, ensuring that the individual is stable and capable of handling the stress associated with driving. This professional guidance helps to mitigate risks not just for the driver but also for others on the road, promoting a safer driving environment.

On the other hand, starting new medication without the advice of a specialist could lead to severe health complications or side effects that might impair driving abilities. Increasing physical workload significantly without proper medical advice can also pose serious risks, especially if the driver’s heart condition is not well-managed. Ignoring symptoms while driving can endanger not only the driver but also other road users and is a clear violation of safe driving practices. Thus, seeking clearance from a cardiovascular specialist is essential for ensuring that the driver is fit for duty and can handle the responsibilities of operating a vehicle safely.
