Do deer whistles prevent deer-car accidents?

This is peak deer season in Ohio, Indiana, and Kentucky, and no doubt you have seen dead deer laying on the side of the highway at some point. One Warren County, Ohio man, whose wife was in an accident with a deer, is wondering if deer whistles might prevent it from happening again. Jim McHugh says his wife recently hit a deer, causing more than $12,000 damage to her car. "A deer came out nowhere, hit the front of her Lexus," he said. "One minute she was driving, the next there was a deer looking at her through the windshield." So he decided to pick up a set of deer whistles, sold at hardware and auto parts stores for as little as $10 a pair.

I’ve used these for over 40 years and more often then not, they do in fact turn away or stop their movement. I drive 3, 000 miles a month in heavy deer country on back country roads in Missouri and I will testify they do actually work.

I don’t care, I’m buying one anyway! If it can save my life, my car and the deer then 10$ is nothing!

I bought the wrong ones, pig whistles now my mother-in-law won't come around.

I've used them for almost 40 years. Plenty of deer where I live. Then recently mine were removed, they were not put back on and three weeks ago I totaled my truck hitting a deer or an elk. You better believe I'm going to buy more and I'll buy the ones with batteries and shrill bells and whistles. I don't care who's getting rich off them I think they work.
I saw another commenter mention that he gives them to his kids for Christmas presents in their stockings. What a great idea for friends and family, especially those still on the fence about it! Thank you for THAT great gift idea and for saving Santa's reindeer, especially Rudolph! LOL LOL

“Have you seen deer” bruh wtf kinda question is that

[jjman]

It's great until you see some deaf deers.

[thomasgregory]

It gets louder as it approaches the animal. It does alert them and it does reduces your chances of actually hitting one.
If you check the motorcycles of long distance riders you will notice that they have them on there too.

Live in co, yes they do work, they either stop and turn back or run away fr the whistling. The only annoyance is... well if u roll down ur window, u can hear the nonstop whistling, but keep them rolled up ull be ok.

Municipalities would be the IDEAL test bed for deer whistles. Install them on 1/2 of the fleet, randomly selected, without advertising which cars do/ do not have them. Collect data for a couple years, badda bing

I have just installed a ladder rack and it whistles at about 30 mph. I have seen it save numerous furry critters, including: a coyote, someone’s dog, raccoons, possum, rabbits, and it has scared deer back into the woods.

I live in MI and talked to my State Farm agent about the whistles. He said that SF ran a test in PA (I think) where they handed out deer whistles to 30% of their clients and the result was a big reduction in deer hits. So they handed them out to ALL their clients and the result was an increase over no deer whistles. Which proved that the deer became used to the whistles and began to ignore them.

I notice a big difference with and without my deer whistles. Seems like every time I drive at night without them, the deer are closer to the road.
Will this prevent? No, but it sure does help a noticable amount and has probably saved my vehicle and the lives of numerous deer. I avoid driving after dark for this very reason.

Your vehicle's front shape creates different pressure zones of air at different speeds, and these pressures change at different driving speeds. The change in air pressure at different elevational zones affects deer whistle performance to the plus or negative sound intensity. Deer whistles produce the loudest sound around 38 MPH on average. Mounting three sets of very inexpensive deer whistles from different manufacturers  (Buy on different brands Amazon) to create different tones, or different amount of sounds at different speeds do to air inlet shape aimed then mounted exactly forward inline with the centerline of the vehicle stacked in three tears of two starting at the lowest point below the bumper and then up two tears allows for a loud noise zone far enough away to avoid deer collisions when driving at night at no more than 40 MPH along rural roads. So...a combination of slower speed maintained at 40 MPH ( not 55 MPH) and more whistles has kept me deer collision free for 45 years of driving while living next to a large reservoir nature preserve often driving at night to and from home in darkness. the deer whistles are black not chrome, and are mounted just behind the vehicle's observable front skin area surface so that the six deer whistles are hard to spot. Also deer whistles mounted recessed do not get torn off in a rotating rubber flap slapping type auto car wash. Hope these explanations of vehicle air movement around a vehicle moving through the fluid of air and proper mounting tips when driving defensively at no more than 40 MPH help everyone stay deer collision free. Oh if you get tailgated at night that is wonderful ! Pull over, let the less courteous night time driver pass and use their vehicle and insurance deductible to make for a deer collision free drive for you by aggressively wanting to be driving ahead of you at higher speeds. You just can't fix stupid. After miles of spring / summer pollen, Fall dry leaf dust particles, and grit, or Winter salt spreading events that clog up deer whistles to make less or no or wrong tones periodically use a squeeze type spray windex novel pressed close to the deer whistles air inlet to pressure wash clean out that deer whistles air inlet so that they stay clean and produce the proper tone that deer respond to best is preserved because you remove road grime build up which has altered the deer whistles orifice tube diameter that creates the appropriate whistle pitch tones.

Conclusion. Don’t waste your time watching this segment.

I been using Deer Whistle for 29 yrs and they do work I use two double whistles on my 2013 Jeep & my 2007 Piaggio mp3 250ie motorcycle scooter! I live near a lake and there dozen of deer crossing the Roads & HWY!! 🤓

[bridgetmeyers]

Yes deer warning horns do work, I have used them for over 20 years and often drive on country roads.

1:09 Dr. Pete Scheifele studies animal hearing.

"I've been working my entire life and no one showed any interest in my research. They gave me the smallest office. The physics professors laugh at me in the cafeteria. Now you come to me begging for help. No! It's too late. I will turn the animals against you! They will launch themselves at your cars, causing untold damage! You will pay! No one will ever laugh at me again!"

[mroclock]

I'm not a scientist, and I'm sure this man has better credentials than me. However, I question if the deer doesn't have time to react after it hears the sound, wouldn't you have to be driving at the speed of sound?

[ThePuddyboy]

Instead of running Diff. Whistles on a Loop on a speaker maybe the Professor should just run a Tape of a Cougar Scream!! LMAO

[MrAlphacallsign]

I install one whistle in my car and every time I get home from work my neighbor ask me if I’m calling him isn’t that weird
