The correct answer is D.
Road rage is the leading cause of accidents. 94% of all traffic accidents are caused by human error and 33% of those accidents can be attributed to road rage.
Each year, around 200 deaths are caused by road rage, mostly deliberate murders conducted by angry drivers. This number has been steadily increasing over time, at the rate of 7 % per year.
People who experience road rage have often internal reasons for the outbursts such as: a mental illness or a personality disorder, stress at home or at work, behavioral imbalances or impulsiveness.
