How to Avoid a Deer Collision

Deer are more active in the fall months, increasing the likelihood of encountering them on the road. Here's how to keep you and the animals out of harm's way.

avoid deer collision

“Deer in the headlights” didn’t become a popular idiom for no reason. There are as many as 2 million collisions between cars and animals every year in the United States, according to the Federal Highway Administration. The vast majority of which involve deer.

Making matters worse, deer populations are growing at the same time animal habitats are being encroached and displaced by urban development. This not only increases the prevalence of deer collisions, but also means they can occur just about anywhere, including cities and suburbs.

The chances of coming across a deer while driving only increase in the fall, which coincides with deer hunting season. During these months, the animals are often on the move and inevitably wind up crossing roadways. Before you hit the road for annual fall foliage road trips, study up on these tips to ensure you, your family and the wildlife stay safe.

Check for Signs

Maybe the most obvious but undoubtedly most helpful step is to be on the lookout for “deer crossing” signs. These are your primary reminders to be on alert, use caution and, if necessary, reduce your speed.

“Deer Crossing” signs, depicted with a leaping stag, are placed by local towns and highway departments in areas known for high deer activity and/or where deer collisions have occurred in the past. They’re most often found in heavily wooded areas like parks and forests, as well as near water.

Use Your High Beams

If you do see a deer on or near the road, turning your headlights on should succeed in scaring them off. It’s best to use your high beams for this. The higher light better illuminates the animal and provides a larger field of vision.

Make sure to only use your high beams when there is no oncoming traffic. The bright light will shine directly into the other driver’s line of sight, limiting their vision and possibly causing a crash.

Consider the Time of Day

While we can never predict when a deer will jump out onto the road, we do know the time of day it’s most likely to happen. The animals are most active when they are grazing, which occurs during the hours surrounding dawn and dusk. Sunrise and sunset are also particularly difficult times of day to drive (the road may be dark, or the sun’s glare could be in your eyes).

Because of these two factors, it’s crucial to be particularly vigilant when you’re driving through deer country around these times. If possible, plan your travels for a different time of day.

Stop, Don’t Swerve

If a deer is in the road in front of your vehicle, you may be tempted to swerve around it. This, however, could make the situation much worse. Deer will usually move when they see a car coming, so swerving into another lane might just put you right back into the animal’s path. Additionally, you’ll increase the likelihood of losing control of your vehicle or crashing into another car.

Use Your Horn if You Must

Deer don’t want to see you any more than you want to see them. In fact, most large forest animals are actually quite timid and will run off at the first sight of a human. However, they may get too scared to jolt and instead freeze in the middle of the road. When this happens, bring your car to a stop and give the animal a moment to move. If this doesn’t work, flick your headlights on and off a few times. Only use your car horn (in short bursts) as a last resort. The noise may cause a deer to get aggressive.

Watch for Herds

You’re driving down the highway when you spot a deer gallop across the road 100 feet down the road. You’ve avoided a potential collision and now you’re in the clear, right? Not so fast. Deer seldom travel alone. If you see one, there will almost always be others nearby. Once a deer crosses, check both sides of the roadway to make sure another one isn’t following.

  • do you recommend the deer whistle device affixed to the front of cars . I understand that they can warn deer an impending conflict

    • info online suggests NOT:Academics have not been impressed with deer whistle performance.

      41 Action News’ sister station in Cincinnati interviewed an animal audiologist who worked on a 2003 study focused on the devices. Researchers tested six different whistles, finding deer can hear them, but it’s likely too late.

      “The amount of road the car is covering per second, by the time the signal actually would have reached the deer, the car would have been close enough probably to strike the deer,” Dr. Peter Scheifele of the University of Cincinnati said.

  • Excellent advice. There are some deer in my local area and I have found that attaching the small and discreet “deer whistles” can help as well. As you drive it forces air into them and they release a high pitched sound at a frequency that only the deer can hear, thus giving them advanced warning something is approaching them.

  • The phrase “deer in headlights” typically is used to describe a situation when someone is frozen out of fear and unable to move. So it’s interesting that putting on your headlights is actually encouraged to frighten them and get them to run away from your car, meaning that the phrase is wildly inaccurate?

    • Are deer less likely to hear an electric powered car approaching vs a gas powered one? If so how could an owner of an EV better equip the vehicle so that deer can hear or sense it’s approach?

    • High beams not so much headlights, you will most likely have your headlights on already at the time the deer are out which is usually dusk and dawn

    Once had a deer that was spooked by a leaf lower jump over the guardrail right on to the hood of my car.

    Thank you , AAA , for pet safety tips for traveling. When I bring my cat to the doctor I put her in a carrier. I put part of the seat belt under her carrier. I loop part of the seat belt through the handle. I fasten the belt.

  • Thank you for pointing out that hunting is a possible cause of deer/car collisions as deer flee from hunters.

    • In my opinion deer hunters scaring deer into the road is very rare. The main reason in the fall that deer run across roads is because it’s mating season. The bucks will chase a hot doe all day; especially at evening, night, and dawn. A doe will run across streets avoiding the bucks until ready to breed. The bucks will cross streets in their continuous hunt for does. Notice after the breeding season there will be less deer crossing the roads. That is the main reason deer cross roads. It’s now getting close to that time in the Northeast so be careful.

  • People should put deer whistles in their front fenders. Only $10.00 and they work to scare off deer and other animals

    I have purchased a set of small devices to be placed on either side of the car’s bumper that supposedly will make a very high pitched whisling noise that scares an animal that is in the road or it will prevent them deer from crossing into the road because of the noise it hears as you approach. My recollection is that they were relatively inexpensive but no way really to tell how effective they are. I never encountered a deer in the road when i was using the devices, but then that may have been nothing but luck. It would be interesting to see if anyone else uses such devices.

  • I have been told in the past that if you jam on the brakes but can’t avoid a hit, that its better to let up on the brakes just before contact so the hood of the car rises back up and less chance that the deer will slide up the hood into the windshield….any thoughts?

    After a deer jumped on my front fender, the insurance agent who was immediately called advised that any fur be left in the grill and shattered lights as verification.

  • While driving at night constantly scan above the edges of the road your headlights just might light up the deer’s eyes before you reach it giving you time to slow or stop before a collision. Most times if you observe one deer there usually are others with it close by. Also, during severe winters use special caution especially on curvy roads, you just might encounter several deer in a heard in the roadway and along the side of roadways licking the road salt off the road. When their food is scarce during a very difficult winter the road salt is a source of nutrient that helps sustain them. Of course this could happen anytime during the winter, however more likely when the snow is frozen ‘solid’ deer are unable to dig to the bottom for food.

  • I have seen that between midnight and just before sunrise are the worse time for an encounter. Best advice is to leave early and drive much slower than the poster limit. This will allow BOTH you and the deer to react…

    Fall is mating season for deer which can also result in them running across the road.

    I see many deer crossing I 95 in Rhode Island. I have noticed if the cars stop for them, they think all cars will stop and they get killed. I blow my horn at different lengths and it scares them and they go back into the forest.

    • I agree! I HATE it when drivers slow down and stop to allow deer to cross without concern…I feel it sets them up to not be afraid of cars and for the next time to be a disaster for some other driver(s). I always honk, flash my lights and even yell to scar them off the road. Good for you!

    I have been working 2nd shift for the past 40+ years. I’ve had plenty of deer interactions. I would say three things have saved my butt all these years. Looking along the sides of the road for the headlights reflecting back from the deer’s eyes. Driving 45-50 MPH on the typical, two lane, curvy back roads we have here in NY. Stopping straight ahead.

  • One evening, around 10pm, a deer ran into the side of my car in CO and was injured badly but was not dead. I did not have a cell phone and went home to call the police. The police on the phone told me to call a bird rescue organization. They said they were too far away and had ample food to feed injured wildlife. I called a friend who was a hunter and by the time we got back, the deer had died. Take care. It is a traumatic experience not only for the deer. PS The deer alert whistle you mention in the previous article must be quite irritating for dogs driving in these cars.

  • hunters do NOT cause deer to run into the road ! their isn’t any state that allows hunting near roads plus hunting area are NOT set up near roads…during the fall,mateing season cause male deers to chase the does..not hunters..the whistles don’t work and mostly deer are on the side of the road watching you pass by as they eat the small vegetation(which grows there because their isn’t any trees at edge of road) at side of roads not stopping for the whistles…very rarely can some organization come in time to save an injured deer if they did come there isn’t anything they can do except put it down which police usually do..they do NOT dig through snow looking for salt ! they are looking for grasses .

    • I am not a hunter and I really like deer and other wildlife. You are right that the mating season makes the deer move more. Deer hunting is not a chase sport (or the deer would win the chase). The hunter hides and waits, and not in the middle of the roads.
      Unfortunately deer can LEAP into the middle of the road from far off the shoulder as they run sometimes and there isn’t time to react. Also, if they happen to just trot across the road they may do a loop turn-around and cross back again yards further down. They don’t just move in straight lines, so I’ve been told to not assume they won’t cross back.
      I will look into the whistle. Maybe installing two is even better than one?

  • I have had deer whistles on my cars for at least 20 years traveling back and forth to the mountains I have never hit a deer. I have watched them turn around and also stop dead in their tracks. Great invention. Less than $10.00

    Maybe it’s my age but I’ve discovered that swiveling my sun visors down to block out the sky when driving at dusk makes vision of the roadway much better. Your pupils get smaller with the light of the sky thus reducing your vision straight ahead. You can see the difference instantly if you experiment.
