BOISE -- Law enforcement officers say the most serious injury crashes and fatalities occur between Memorial Day and Labor Day. It is what they call the 100 deadliest days.
This year, Idaho State Police put extra patrols on the roads to try to keep drivers safe.
We know the roads will be busy tonight with many families traveling back home from the holiday weekend.
Today marks the end of the summer stretch where law enforcement says they see the most accidents.
Idaho State Police say they don't have the statistics yet to find out whether the number of crashes during the last 100 days has gone down. But authorities believe the program is working, and they're getting a clear message to drivers.
You may have noticed a few more patrol cars on the road this summer.
They were there for a reason, trying to decrease the number of crashes during the 100 deadliest days.
"The grant from ITD paid overtime shifts for officers who would normally be off to come in on to work the roads in areas that were high crash or problem areas," said Andrew Nakashima with the Idaho State Police.
The Office of Highway Safety started the program that was new this year in Idaho.
Officers were trying to battle aggressive driving in hopes of keeping roads safer.
"That was our main focus, the following distance of cars, and we encourage people to back off the car in front of you," said Nakashima.
They also want to remind drivers not to be distracted behind the wheel.
As for whether the campaign worked, officers say preventing even one accident is deemed a success.
"Everyone involved in the process of making the roads a better place, from ITD engineers and people who came up with this program, law enforcement officers would like to think that everything we do makes a difference in people's driving habits," said Nakashima.
ISP also wanted to remind drivers that the roads will be busy tonight, so be patient and plan for extra driving time.
At KTVB we've partnered with Idaho State Police and the Idaho Power Company to help decrease distracted driving.
We've been reminding people of the dangers of texting and driving and encouraging you to take the "Just Drive" pledge with us to stop the dangerous practice.
