It's something we've seen a lot over the past few weeks, people driving the wrong way down valley freeways causing accidents, some of them deadly.
The Arizona Department of Transportation is taking some new steps to keep drivers safe.
There are more than 100 interchanges along the freeway system. The one at I-17 & Carefree Highway got new signs Wednesday.
Five people have died in wrong-way crashes over the past two months. FOX 10 asked drivers if a change in signage was part of the solution?
"I don't think the signs are enough, I honestly don't think people read the signs, but if they're impaired or they're not paying attention it's not going to do any good," said Paul Foster.
The new larger signs are being placed at six freeway interchanges. They have a history of higher wrong-way incidents based on 911 calls received by DPS.
The wrong way signs have increased in size from 36 x 36 inches to 48 x 48 inches. Also on the roadways, reflective large arrows.
"They're pointing the right way, but the use of red reflectors in those arrows again is another measure we hope will get the attention of the wrong way driver before they get on the freeway," said Doug Nitzel with ADOT.
"It's wonderful that they're addressing the issue because something needs to be done," said Debbie Rimbey.
The people we spoke to about the changes were hopeful but skeptical.
"I'm not so sure that signs are enough, I'm afraid that people that do make those mistakes a lot of times are impaired or not familiar with the area," said Rimbey.
Is this the solution to solve all the wrong-way crashes? No, the recent crashes have all involved drivers who were allegedly impaired.
