Every holiday weekend has a large number of DUI / Drunk Driving checkpoints scheduled. Last week's St. Patrick Day weekend was no exception. However, since last weekend's heavy rains resulted in mass cancellations of DUI / Drunk Driving checkpoints, it looks like police agencies will be making it up big time this weekend. These checkpoints are usually funded by Federal and State governments. Unless checkpoints results in arrests, police agencies would be hard pressed to have their DUI / Drunk Driving checkpoints funded in the future. As a result, there will be a large number of DUI / Drunk Driving checkpoints this weekend. Every week, I post known Southern California (sometimes Northern California as well) checkpoints that have specific locations and times at http://www.topgundui.com/about/dui-checkpoints/. Later today, I will be posting checkpoints for this weekend.
