Arizona's Department of Public Safety is sending a word of caution to drivers about making U-turns on highways.
A dashcam video shared by DPS shows the driver of a semi-truck barely being able to stop in time to avoid rear-ending the driver of a truck.
The truck driver slows down significantly and quickly to make a U-turn in the center median while in front of the semi that's traveling at a highway speed.
"This dash cam from a semi driver shows just how dangerous it is to slow down abruptly from highway speeds to turn into the median," DPS said in a tweet.
"Ever wondered why ‘No U-Turn’ signs are posted at median crossovers on controlled-access highways such as I-10," DPS asked.
This video is the answer to that question.
