This labor day weekend, across the nation, DUI police officers will be at drunk driving checkpoints. Their goal, to get as many drunk drivers as possible off the highways, and reduce the injuries and deaths caused by impaired drivers.



Sobriety checkpoints are not legal in all states. Where they are legal, they are employed with differing degrees of effectiveness.



In Scottsdale, Arizona, the police department has announced the date, time and location of their planned checkpoint. Perhaps their reasoning is that anybody who drives into it with alcohol in their system must be drunk.



I have written elsewhere about DUI checkpoints. My argument is, essentially, that they are a publicity stunt and a waste of resources.



As with any publicity campaign, hopefully the message will reach some would-be DUI drivers, who will then make the right decision and call a cab.



Here's wishing everybody a safe and happy holiday weekend.
