Who can drive alone?
Those who have been assessed and rendered fit and safe to drive by the physician can drive alone:
- Hypertension which is under control is not a contraindication to driving unless there is any target organ damage that may result in sudden collapse.
- If the driver is seizure free and off anti-epileptic drugs for more than 10 years then he can drive alone.
- Once the patient is on a suitable dose of anticoagulants, in the case of thromboembolism or deep vein thrombosis, he can safely drive.
- The driver can safely drive wearing contact lenses as long as he is adapted to them, but he cannot use a lens in one eye for near vision and in the other eye for distant vision at the same time.
- Patients suffering from arthritis can drive as long as the pain and stiffness doesn’t incapacitate them.
- A person can safely drive if the physician has prescribed a drug and assured that it will not interfere with the ability to drive in any way.
- If the driver can successfully meet the audiometric test after using a hearing aid, then he can drive alone.
It is necessary that each one takes up the task of responsible driving for his/her own as well as public safety.
