How does heavy amphetamine use affect a driver's coordination?

Heavy amphetamine use significantly disrupts a driver's coordination and overall ability to operate a vehicle safely. Amphetamines are stimulants that may initially create a sense of heightened alertness, but as the effects wear off, users often experience fatigue and impaired motor skills. This leads to a decrease in coordination, making actions such as steering, braking, and responding to sudden changes in traffic less effective.

Increased crash risk arises because impaired coordination affects a driver's ability to maintain proper control of the vehicle and react appropriately to other road users or obstacles. The effects can be debilitating, resulting in poor judgment, slower physical responses, and an inability to process information quickly. Therefore, heavy amphetamine use is closely linked to a heightened potential for accidents on the road due to these negative impacts on a driver's coordination.
