In this scenario, the independent variable is the cell phone use because it is the variable that is being manipulated to see its effect on the dependent variable (likelihood of having an accident). The dependent variable is the outcome which is being measured and the control variable is a variable that is held constant to prevent its influence on the dependent variable. Extraneous variables are any other variables that may interfere with the relationship between the independent and dependent variables.
