As if trying to drive on the freeways the day before Thanksgiving wasn't frustrating enough, the Arizona Department of Public Safety has decided to slow things down a bit.

To the speed limit, to be precise.

Operation Safe Passage, as it's been dubbed, will put a truckload of extra DPS officers on interstates 8, 10, 17 and 40 — what, no love for I-19 — the rest of Wednesday and overnight, all in hopes of cutting down on speed- and alcohol-related crashes.

According to DPS, last year's Wednesday-before-Thanksgiving saw 12 fatal wrecks, which killed 13 people.

DPS says it will have one of its vehicles stationed every 10 miles on the abovementioned freeways where they go through rural areas, while in the urban corridors that will drop to every two miles.

So, if you were planning on making the 100-mile drive from Tucson to Phoenix tonight in just over an hour ... well, you've been warned.
