Using cell phones when driving and using drugs, including alcohol.
Alcohol affects a driver by impairing cognitive and motor skills, reducing reaction time, decreasing coordination, and altering judgment. This can lead to dangerous driving behaviors, an increased risk of accidents, and impaired decision-making on the road.

Reaction time
Driving reaction time is the time taken for a driver to see something in the road ahead and to react. This is separate to the braking distance.
Reaction time is the length of time that passes between perceiving a problem and beginning to do something about it. Depending on the driver's physical and chemical state, it can vary from a fraction of a second to several seconds. Note that this has nothing to do with the skill of the driver, and does not imply that the action taken will necessarily be appropriate or properly executed.
The average driver's reaction time is about 1.5 seconds. This is the time it takes for a driver to perceive a hazard and begin to react to it, such as by braking or swerving. However, reaction times can vary based on a variety of factors including age, fatigue, distractions, and alcohol or drug use.
Alcohol affects a driver by slowing their reaction times. It can also make a person drowsy, reduces concentration, and may make a person feel more confident in their driving abilities.
The reaction time of a driver is .75 seconds ... or 1 car length for every 10 mph that you are traveling. This can vary depending on things like cell phone usage, radio distraction and more.
It takes longer for an impaired driver to process what is happening.
