A good portion of our nation's infrastructure relies heavily on the long hours spent by highway workers repairing and maintaining our roadways. Here in Georgia, with our many busy highways, much of this maintenance and repair must be done during the late evening and early morning hours. While these hours are typically quiet on the highway, late night bar patrons and other partygoers may make up a good portion of the traffic. Ideally, each late-night commute is made by a completely sober and wide-awake driver. Unfortunately, this is not always the case. And, many vehicles speeding past road workers may actually be driven by a drunk driver.
