NASHVILLE, Tenn. -- An I-Team investigation reveals where Nashville drivers are most likely to be victims of a drunken driving crash and when a crash is most likely.

Joycelyn Gardiner was on the right track in life until she reached the intersection of Nolensville Road and Old Hickory Boulevard.

"We were planning a graduation party for her in December," said Gardiner's cousin, Madalyn Milson. "Instead, we had to send her body back in a box in the hull of a cargo plane."

Gardiner, a track star at Tennessee State University, was killed by a drunken driver last year while driving home.

The intersection in which Gardiner was killed is one of the areas of Nashville the I-Team found where drivers are most likely to be hit by a drunken driver, according to statistics.

Certain roads intersections around Nashville also increase risks even more.

The I-Team analyzed federal data and Metro drunken driving crash records from over the past three years and found that, on average, there have been four drunken driving crashes for every mile along Old Hickory Boulevard since 2004.

"I try to avoid it now because of the tragedy that we're experiencing, but I also try to avoid it because I now realize how dangerous it is," Milson said.

Old Hickory Boulevard had the most with 257 drunken driving crashes.

The street with the second most drunken driving crashes was Murfreesboro Pike, with 226; Nolensville Pike was third, with 179.

But knowing the streets cover such a large area, the I-Team also calculated the four intersections where most drunken driving crashes have occurred.

In the past three years, there have been 10 drunken driving crashes at the Nolensville Road and Old Hickory Boulevard intersection where Gardiner was killed. But the intersection still doesn't have the highest number of drunken driving crashes.

Nolensville Pike at Harding Place had 11 drunken driving crashes, and there were also 11 at Lebanon Pike at Briley Parkway.

So why do these streets and these intersections have so many crashes?

People who have been drinking have to get home and the pikes and parkways connect almost every neighborhood in town, and the areas are also covered in stoplights and intersections.

Crash investigators said residents who drive after 10 p.m. should stay away from pikes and parkways in Nashville if they want to maximize their chances to avoid drunken drivers.

"There's more things for an impaired driver to have to negotiate," said Metro Fatal Crash Team Sgt. Jeff Keeter.

But a longer the road doesn't always mean a larger number of drunken driving crashes.

Broadway, which is roughly 2 miles of bars and honky-tonks in downtown Nashville, saw 91 drunken driving crashes in three years. The number on Broadway is more than either Dickerson Pike or North Gallatin Pike, both of which are considerably longer.

Statistics also show when and how drivers are most likely to be hit by a drunken driver in Tennessee.

According to the U.S. Department of Transportation, a drunken driving crash will most likely happen on a Saturday night in May with no rain, and the drunken driver will hit a victim head-on.

Milson found the statistics sobering.

"There was a slogan when I was young and it was, 'Watch out for the other guy.' And I guess that's what we all need to do," she said.

While the I-Team pointed out where most drunken driving crashes occur, police point out that the crashes can happen anytime at any place.

Any person who has been drinking can call for a free ride home and a tow for their car on the nights of Friday, May 3, through Monday, May 5. Drivers should call 1-800-AAA-HELP for the offer.
