What can affect ability to drive in a similar way to alcohol?

Both medications and drugs can impair your driving ability similarly to alcohol. Certain medications, especially some painkillers, sleeping pills, or allergy medicines, can cause drowsiness, slow reaction times, or reduced concentration. Illegal drugs or some prescription substances can also affect judgment, coordination, and alertness. Soft drinks, however, do not impair driving. Understanding this helps you recognize that not only alcohol but also other substances can make driving unsafe and increase the risk of accidents.
