Substance abuse can impair a person’s cognitive and motor functions, leading to poor judgment, reduced reaction times, and decreased coordination. As a result, individuals under the influence of drugs or alcohol are at a greater risk of causing or being involved in road accidents. The use of drugs or alcohol can also cause drowsiness, reduce concentration, and impair vision, all of which can increase the likelihood of accidents on the road. Therefore, it is essential to avoid driving under the influence of drugs or alcohol to prevent such incidents. Additionally, educating people about the risks of driving under the influence, providing alternative transportation options, and enforcing laws that discourage driving while intoxicated can also help prevent substance abuse-related road accidents.
