You might have passed your driving test with flying colors and never text while driving, but it turns out there are a lot more bizarre things that can affect how dangerous you are on the road.
Music is important when you are driving. You’d be hard pressed to find a car that didn’t at least come with a basic radio and lots of people will spend thousands of dollars making sure they have the best aftermarket stereo systems available. But listening to music contributes to hundreds of car accidents every year. People fiddling with the radio will look away from the road. Even the type of music you listen to can affect your driving; high tempo music, like techno, makes you twice as likely to go through a red light, for instance. But possibly the worst thing to do is sing along to your favorite tunes. Even when singing a song you know by heart, your brain has to work to remember the melody and the words. This increases the workload on your brain and in turn makes it harder to react to dangerous situations when driving. So next time you are out for a drive, maybe leave the ballads to Beyoncé and concentrate on the road.
2. Having a Cold
Your health can have an obvious effect on how well you drive. After all, if you aren’t getting enough sleep, or are in chronic pain, or seriously ill, you are going to react slower to danger. But it doesn’t have to be some major health issue that makes you a worse driver.
A 2012 study found that even a slight cold is enough to make driving a car more dangerous. In a driver simulation, researchers found that people with a cold are more easily distracted while driving, have slower reaction times and are more likely to follow the car in front too closely. So next time your boss says that a cold isn’t a good enough reason to miss work, tell her you are just being a responsible driver by staying home.
