( CNN ) Most road rage incidents do n't amount to much . Some shouting . A few harsh words . A rude gesture or two . Everyone gets it out of their system and life goes on . But sometimes it takes a tragic turn . Last week in Las Vegas , a mother of four was killed in an apparent road rage case . Police say Tammy Meyers died of a gunshot wound to the head after a suspect followed her home and opened fire . Meyers and the man argued over a traffic incident earlier in the day . A study published in the International Journal of Psychiatry in Medicine in 2010 concluded that one-third of the people it surveyed reported road rage . A 2013 Washington Post poll said the number of drivers who say they feel `` uncontrollable anger toward another driver '' has doubled from eight years earlier . The number is 12 % , or more than 1 in every 10 drivers on the road . A couple of things appear to be making matters worse , much worse : cameras and guns . In this age of social media , it seems natural to document everything in our lives . But experts say snapping a photo or video of the person you feel has wronged you on the road does n't help matters . Back off from aggressive drivers . If you get cut off , back off , take a deep breath , and remain calm . Now you 're read for what comes next . If you need to vent , wait to you get home , then talk to a friend . Know your driving style . If you 're an aggressive driver , you might be the problem . Are you provoking other drivers ? These are the habits of aggressive drivers : . Tailgating . Overuse of the horn . Flashing headlights . Changing lanes quickly , often and without signaling . Guesturing to other drivers . Talking or texting on your cellphone . -- from DMV.org . In a video posted this month to YouTube , a man in Austin , Texas , is seen cursing at a woman and spitting on her windshield after she photographs his license plate . The man was charged with reckless driving and later apologized for his behavior . Last month , a mother in North Carolina began to videotape another driver she said was acting aggressively . `` This person in front of me is being a real ... character right now , '' she says on the video . Moment later , the driver is seen lashing out , banging on the woman 's car window : `` You stupid ( expletive ) . '' `` You 're taking the chance of shooting footage of someone who 's enraged and could that further enrage them ? It 's hard to say ... but you 're taking a risk , '' said Jeffrey Spring of the AAA of Southern California . `` The most important thing ... is to get out of the situation , '' he said . `` You do n't want to escalate it to that point where there 's someone so enraged where they 're not thinking about what they are doing . '' With guns just slightly less ubiquitous than cameras these days , drivers face a second far greater risk in road rage incidents . In 2013 , David Kollar was driving on Interstate 75 near Lexington , Kentucky , when he noticed a man driving recklessly in and out of the emergency lane . He pulled out his phone and started shooting video . First , he tried to get the license plate number , then Kollar pulled alongside to get a shot of the driver . That 's when the man driving the car rolled down his window and appeared to fire a shot . No one got hurt , but lesson learned . `` I was scared , '' he said . `` It was a little crazy . '' Late last year , a family in Atlanta narrowly escaped after a driver opened fire , after a roadway altercation . The gunman followed them to a strip mall and started shooting . The family dog jumped in , taking a bullet for the family . `` They were fired upon and their family was terrorized , '' Atlanta police Sgt.Gregory Lyon told CNN affiliate WXIA . `` They survived that only to find that their pet is now gone . '' So what can be done about it ? Last year , AutoVantage came out with a road rage survey . It found that drivers in Houston , Atlanta and Baltimore are the least courteous . Portland , Pittsburgh and St. Louis are at the most . DMV.org offers some suggestions on how to handle road rage . Back off from aggressive drivers : You ca n't control them so give them some room to operate . Know your own driving style : Maybe you 're the bad guy or gal . Maybe you 're provoking the drivers around you . And here 's another thing to think about . You never know who 's behind the wheel of the other car . They might just be having a bad day or maybe have some serious problems . Or you could find yourself in a situation like the one portrayed in a Georgia public service announcement featuring Evander Holyfield . An angry man , who calls out a driver who cut him off , finds himself face-to-face with the menacing former heavyweight champ . The punchline ? `` Avoid road rage . You never know who you might run into . ''
A Washington Post poll says road rage is increasing . Road rage advice from the National Highway Traffic Safety Administration suggests that drivers should slow down and be more careful when passing other vehicles.
