Impaired drivers who present potential hazards may tend to _________.

Impaired drivers:
Drivers who are sleepy, have had too much to drink, are on drugs, or are ill are hazards. Some clues to these drivers include:
- Weaving across the road or drifting from one side to another.
- Leaving the road (dropping right wheels onto the shoulder, or bumping across a curb in a turn).
- Stopping at the wrong time (stopping at a green light, or waiting too long at a stop).
- Open window in cold weather.
- Speeding up or slowing down suddenly, driving too fast or too slow.
Be alert for drunk drivers and sleepy drivers late at night.
