As you say it is missing a step.

"If you (drink and) drive you might get in a car accident.
*** You should not run the risk of getting in a car accident
Therefore you should not (drink and) drive."

You need to match 'ought to' or 'should', or equivalent meaning word in the 
minor premiss in order to be valid.

Note I put 'run the risk of' to cover your 'might'.    Better still would be

If you (drink and) drive you run the risk of getting in a car accident
You should not run the risk of getting in a car accident
Therefore you should not (drink and) drive.

You need to match the pattern of

If A then B
B should not happen
Therefore A should not happen

The logic is quite simple.  Suppose A happens. Then from the major, B will 
happen.  But from the minor, B should not happen.  Thus if A happens, 
something will happen that should not happen.  Therefore A should not 
happen.
