Safety in public transportation is a critical subject which is always under experiment. Safety in driving, not only saves driver's life and people in the car, but also saves other's lives which are passing by. It's purely important that drivers will be always under control by checking their mental and physical health. Government must have strict laws regarding this matter because when an accident happens, beside the expenses that have been ocuured, many lives might be in danger which is not irreparable. It's totally a correct opinion that drivers must repeat tests every year otherwise their driving lisence will be expired.
