A more thorough explanation:

Driving while ability-impaired is the offense of operating a motor vehicle while physically or mentally impaired, especially after consuming alcohol or drugs. It is also known as driving under the influence (DUI) and is a lesser offense than driving while intoxicated (DWI) in most jurisdictions.

Examples of driving while ability-impaired include:

• A driver who has consumed alcohol and is swerving on the road
• A driver who is under the influence of drugs and is driving erratically
• A driver who is tired and falls asleep at the wheel

These examples illustrate how driving while ability-impaired can be dangerous and put the driver, passengers, and other people on the road at risk. It is important to never operate a motor vehicle while impaired and to always find a safe alternative, such as calling a taxi or using a designated driver.
