Which of the following driving skills is/are affected by the use of alcohol and/or drugs?

1. Alertness

2. Coordination

3. Both of the above

4. Neither of the above

The correct answer is: Both of the above

Alcohol and drugs can significantly affect a driver's ability in various ways. Both alertness and coordination are essential driving skills that can be impaired when under the influence of alcohol and drugs. Alcohol and drugs can reduce a driver's alertness, leading to slower reaction times and an inability to respond quickly to changes in traffic conditions. Additionally, these substances can impair coordination, making it more challenging to maintain proper control of the vehicle, such as steering accurately and braking appropriately. Therefore, the correct answer is "Both of the above" as both alertness and coordination are affected by the use of alcohol and drugs, impacting a driver's ability to operate a vehicle safely.
