The dangers of using mobile phones whilst driving have been well documented. Department of Transport statistics for 2012 showed mobile phone use was a factor in 378 incidents, which caused 548 injuries and 17 deaths. In 2008 a study* by the Transport Research Laboratory showed that texting while driving could increase reaction time by 35%, compared to 21% for smoking cannabis and 12% for being at the legal drink drive limit.

In 2013 a truck driver was seen to delete texts from his phone after he had been involved in a crash that resulted in the death of a thirteen year old girl. That case illustrates the central message in this article – we know the use of mobile phones slows our reaction times, we know we shouldn’t use them while driving and yet a lot of people still do. The question then is why?

In some cases, but by no means all, the problem can be attributed to employers who want to be in contact with their drivers all the time but, in the main, it’s more to do with the modern phenomenon of social media and the habits that it can instil in us. A lot of people will have had the experience of putting something on social media and then thinking “Let’s see if that post gets any likes or increases our followers.” There is a natural desire to be in contact with other human beings because we are social creatures, to the extent that it can often override our use of common sense.

For many of the sub 50 generation there is a natural tendency to answer a text immediately it arrives, despite the fact that the sender won’t even know if the phone is even switched on. It’s one of the most basic and powerful examples of behavioural conditioning in modern life. At that moment when the phone rings, buzzes or bleeps, it’s almost as though we have no other option but to answer it or reply to the text.

The conditioning itself takes place easily. As stated before, we’re naturally social creatures, so our reward for answering the phone is social interaction, and, although a small reward in itself, it’s enough to condition us to respond to the phone, in preference to continuing to deal with the situation we’re in.

In some cases we want to initiate the call to activate the social interaction and the same behavioural influences are brought to bear. We’re effectively rewarded for our efforts. Even drivers who don’t actually use mobile phones when they drive will be aware of that moment when either the phone rings or there’s the buzz of an incoming text, which takes their attention off the road for that vital split second.

That leaves us with the problem of what to do about this situation. For responsible drivers, who are likely to have had some form of advanced or defensive driver training, it’s simple – it’s instinctive to turn the phone off when driving and let that voicemail function do what it was designed to do all along.

But, trained drivers or not, it’s vital that businesses robustly apply their mobile phone policies, even if it means using negative reinforcement to reverse the conditioning effect and improve driver behaviour. The use of mobiles while driving, particularly hand-held, should be a disciplinary offence for the employee, with all the consequences which that brings.

Also I don’t believe I’m alone in saying that we need to outlaw the use of mobile phones entirely while driving, whether hands free or not,. Until that happens there should also be far heavier penalties nationally for the illegal use of hand held mobiles and rigorous application of the ‘dangerous driving’ offence when they clearly play a contributing part in a collision.

In addition to legal penalties there should also be social penalties. Anyone who uses their phone whilst driving should be made aware that it is unacceptable, in the same way that drink driving is reviled and the use of seatbelts, for the vast majority of drivers, is second nature.

Sadly mobile phone use on the move is a relatively new phenomenon in terms of human behavioural development and change won’t happen overnight, but the fleet industry can play an important role in getting this message across and helping this essential attitude shift to occur.

Insurance data harvested over many years demonstrates that the under 24s are at a much higher risk of becoming involved in road collisions than any other age group. There seems to be a general assumption that young drivers fall into this category because they are inexperienced and impetuous.  To some extent that is true but the greatest influence is the significant change that occurs in our brains during adolescent years.

Just fifteen years ago it was assumed that most of the major changes in our brain happened in the very early years.  But then along came Magnetic Resonance Imaging (MRI) and neuroscientists suddenly had the ability to look inside actual living brains.

The main area of the brain that concerns us here is the prefrontal cortex.  The prefrontal cortex in human brains is proportionately much larger than in any other species.  It is involved in a lot of our higher functions, such as planning, decision making, inhibiting inappropriate behaviour and so on.  That latter point is an interesting one; it stops us saying things that can offend and doing things that are stupid.  So it is very important in modern society; it helps us understand other people and contributes to our sense of self awareness.

It is an area of the brain that goes through a lot of changes in our adolescent years.  During that period, the connections in our brain are fine tuned and the connections that appear to serve us well are strengthened, whilst those that don’t are pruned away.  From a driving perspective, the most important change comes between the age of fourteen and early adulthood, i.e. approximately twenty years of age.

As children and adolescents we have less ability to see things from other people’s perspective.  That is in the literal sense of ‘If I can see them they can see me’, which as adult we know isn’t always true.  As adults we are more familiar with the rules of the road and are more easily able to anticipate other people’s actions.  That may appear to be another way of saying adults have more experience but the fact is the grey matter in the prefrontal cortex changes a lot in adolescents and exaggerates their lack of experience.

The biggest change though is in taking risks.  Adolescents are particularly prone to taking risks when they are with their friends.  There is a significant drive to become independent from parents and to impress friends during that period.  There are physical rewards for adolescents, in that the limbic system within the brain becomes active when risks are taken and are successful.  There is literally a reward system for risks.  It is true for adults too, which is why we have extreme sports like bungee jumping but in adolescents the limbic system is hypersensitive and rewards risk taking disproportionately.

So what we have in adolescents is a prefrontal cortex that is not sufficiently developed to stop us from doing things that are inappropriate, combined with a hypersensitive limbic system that rewards risk taking and an inability to see things from other people’s perspective.  Perhaps we can now begin to understand why there are so many incidents involving young people on the roads! Hardly surprising then that the average fleet manager thinks twice about giving a driving-related job to an under 24 year old.

That may appear to be a bleak picture for adolescent road safety but there is a very positive note to strike here.  Our environment helps to shape the adolescent brain so if we are taught road safety in an engaging way from an early age that will help to shape our attitudes later on.  The very malleability of the brain in adolescent years is sometimes seen as a problem but it can also be the solution.  If good driving tuition is provided in our pre-adolescent and early adolescent years it can almost literally shape our thoughts for the future.

Young men go through adolescence a couple of years later than young women, which is probably why the term ‘boy racers’ springs so easily to mind and they tend to hit that point in their lives just as they are starting to drive.  The key is to give them the right guidance in a manner which is acceptable to them in these crucial years, a time when self image is everything. Making road safety ‘cool’ is a tall order perhaps but it may be the only way to change the dangerous driving habits of a generation.
