Which driving symptom might indicate that a driver is impaired and their actions unpredictable?
a) weaving from side to side
b) erratic change in speed running
c) stop lights and stop signs
d) all of the above

D) All of the above

Explanation:

When a driver start to weave from side to side that means you never know if they are going to come straight into your lane even if you are driving on another lane or if they leave your lane they may still weave back so it is better to halt or pass the driver of possible.

Also someone who starts to speed up all of suddenly can't be predicted.

Running on stop signs and stop lights is also dangerous because the person may crash against those who follow the stop signs and light properly so when you yield or stop there you can not predict their next move if they running through these lights.
