Driving is the most dangerous activity you engage in on a regular basis. It deserves your undivided attention. Nevertheless, a lot of people are still driving while distracted. You might be one of them. If so, there’s one question you should ask yourself: Why?

Why are you still driving while distracted? Here are some possible reasons you might give.

You don’t know it’s illegal.

In California, it’s against the law to use a hand-held phone while driving. This means that when you’re behind the wheel, you can’t talk on the phone, text, check your email, take photographs, use your apps, play games, surf the internet, read an e-book or do anything else with your phone. If you break the law, you could be face an expensive ticket.

You don’t think it’s that big a deal.

In a 2016 survey, the majority of California drivers reported having been hit or nearly hit by distracted driver. This is despite the fact that 3,477 people died and 391,000 people were injured in crashes linked to distracted driving in 2015. Distracted driving is a very big deal.

You’re too busy not to.

You have a lot to do, and time spent stuck in traffic can seem wasted. You know what would really mess up your busy schedule, though? Getting pulled over by a police officer. Crashing your car. Being hospitalized.

You think you’re good at it.

Zendrive analyzed the behavior of 3 million drivers and 570 million trips to determine how common distracted driving was. The study revealed a scary statistic: drivers use their phones during 88 percent of trips. This is despite widespread acceptance that distracted driving is dangerous.

Many people seem to believe they are the exception. Other distracted drivers are a menace, the thinking goes, but I can do multiple things at once without messing up.

If only it were true.

Unfortunately, scientists say that multitasking is a myth. People simply aren’t good at doing multiple things at once. According to Psychology Today, people who think they are multitasking aren’t really doing two things at once. They’re just switching back and forth between tasks. The result is an increase in errors and a 40 percent loss in productivity. This might not be a huge deal if you’re watching television while texting, but if you’re driving while texting, the resulting mistakes can be deadly.

The worst part is that people are notoriously bad at judging their own multitasking abilities.

You can’t resist the temptation.

Nomophobia – the fear of being separated from a cell phone – is real. Psychology Today reports that two-thirds of adults suffer nomophobia. For many people, turning their phone off results in anxiety. Hearing a notification ping without being able to respond is even worse.

But it’s not as bad as a car crash.

When you’re driving, silence your phone and put it out of sight. This will help you forget about it. Tell your friends, family and colleagues that you won’t answer your phone while driving, but you’ll get back to them as soon as you park. And if the temptation really gets to you, pull over somewhere safe.

A lot of people drive while distracted. They all have their reasons, but none of them are good excuses. Distracted driving is as dangerous as it is common, but we can change this. Do your part by taking the Dashers Pledge.
