Driving requires the full attention and concentration of the person behind the wheel, and their health can significantly influence their driving abilities.

Being ill or taking certain medications can severely affect the driver’s reflexes and decision-making abilities. In this note, we will explore some situations where driving is not a good idea.

Physical Incapacity

If you feel fatigued, muscle weakness, dizziness, or other symptoms that do not allow for 100% mobility, it would be best not to drive to avoid endangering your safety, that of your passengers, and other people on the road.

Reduced Concentration

Being ill often involves congestion, fever, and general physical discomfort that can decrease the driver’s concentration and attention. These causes can lead to slower decision-making and even errors in judgment.


Some medications, even over-the-counter ones, can have side effects such as drowsiness and dizziness. These symptoms are dangerous when driving, drastically affecting the driver’s ability.

Risk of Illness

Some illnesses have a greater likelihood of fainting or sudden loss of consciousness, which could have catastrophic consequences if that person is the driver of a vehicle.

So, when should you refrain from driving?

  • If you have a fever or severe infections,
  • If you experience side effects from the medications you are taking,
  • If you have severe symptoms that affect your driving ability,
  • If you suffer from extreme fatigue.

Stopping driving for a few days may be uncomfortable, we understand. But it’s even worse to suffer an accident that could have been avoided. During your illness, especially when you feel worse, it is advisable to stay away from the wheel and rest so your body can recover.

Remember! Your safety and that of everyone on the road is a shared responsibility, and each of us must be aware of the potential consequences of our decisions and actions.
