You'll need to hit the brakes if you're hitting the road over the Memorial Day weekend.
The Arizona Department of Transportation says they are implementing a speed reduction along Interstate 17 this weekend.
Speeds will be reduced by 10 miles per hour on Friday and southbound on Monday between New River and Sunset Point on I-17.

An ADOT study found that law enforcement cited "speed too fast for conditions" in more than 40 percent of I-17 crashes that occurred in the Black Canyon City region between 2011 and 2015.
Additionally, ADOT is hoping drivers will practice safe-driving techniques to achieve a goal of no fatalities on the road during the holiday weekend.
ADOT says 1971 was the last year no deaths were recorded on our roads during Memorial Day travel.
Five deadly crashes occurred over the holiday in 2017, down from seven in 2016 and 11 in 2015.
Aside from speed reductions, ADOT is planning to have more vehicles out so they can respond to crashes faster and reduce delays on other high-traffic stretches like Interstate 10 between Phoenix and Tucson, and State Route 87 between Mesa and Payson.
