Cocaine leads to a sense of over confidence and this is reflected in driving style. Users typically perform higher risk, more aggressive manoeuvres at greater speeds, which is obviously dangerous.
The specific effects of driving on cocaine are:
Poor control of the vehicle
Over-confident, high risk behaviour
The following effects are likely to occur once someone has stopped taking the drug and are related to the fatigue that results from cocaine use:
Distraction and drowsiness
Falling asleep at the wheel
