Terrifying proof texting at the wheel is MORE dangerous than drink driving... and hands-free calls are almost as bad


  • Texting behind the wheel slows reaction time by 25 per cent
  • Eating a sandwich means you are 27 per cent worse at keeping a distance
  • Drinking alcohol increases your risk of swerving by 74 per cent

Cruising along the middle lane of the motorway at 70mph, I pick up my smartphone from the passenger seat and start composing a text message about my plans for the forthcoming weekend. ‘What’s the harm?’ I wonder. The motorway traffic is moving steadily and it’s only going to be a quick text. Besides, I’m sober and alert.
Still, I hold the handset low — so passing motorists cannot see what I am doing — as I lower my eyes and start jabbing at  the screen with my right index finger... ‘CU @ 12,’ I type, before pressing send.

It took barely a second but when I glance back up, the first thing I notice are the red brake lights of a lorry ahead.

With an impact imminent, I don’t have time to check my rear-view mirrors. I take immediate evasive action, single-handedly swerving into the overtaking lane.
It is a close shave but, more by luck than judgment, I just get away with it. My heart thudding, I drop the phone into my lap and ease into the inside lane, hoping that no one important has spotted my terrible driving.
But there is absolutely no chance of that.
 

The Honda Civic I am driving is in fact a high-tech simulator located deep within the bowels of the Transport Research Laboratory in Berkshire. While it looks, drives and moves like a normal vehicle, it has no engine — the lorry I nearly rear-ended and the motorway I have been driving along are part of an ultra-realistic film projected on to screens that surround the car on all sides.

As I operate the car, my speed, braking, road position and eye movements are all recorded, the data fed in to a bank of computers monitored by scientist Dr Nick Reed, who is the senior human factors researcher at TRL, one of the world’s leading transport research centres.

I’m here to test out new research that suggests texting is the most dangerous thing a person can do at the wheel. TRL scientists found that a driver’s ability is impaired far more by texting than it is by a couple of drinks, talking on the phone or eating a sandwich.

But can this be true? To find out, my reaction times and driving skills were tested while completely sober, and with no distractions. 

I was then put through the same tests while texting, talking with my phone to my ear, talking on a hands-free phone, eating a sandwich and having consumed enough alcohol to exceed the drink-drive limit. The results horrified me.


Making a hands-free call

While it is legal to use a hands-free set while driving, if the police think you are distracted and not in control of your vehicle you could still be penalised. And judging from the results of the tests I underwent, that is a very real risk.

To replicate the effect of having a hands-free phone conversation, Nick communicates with me via an intercom, running through a series of questions and mental challenges as I drive.

These include simple maths puzzles (‘if three chocolate bars cost 93 pence, what is the cost of one bar’) and sentences that I have to repeat (‘Annie’s dog ran to her for help after it was attacked by a raccoon in the woods’).

Unpredictable: Even though using a hands-free phone is legal, police can still penalise you if you are not in control of the car

The idea is to occupy my mind to a similar degree as when engaged in, say, a conversation about work. And occupy it the raccoon most certainly does.
To measure my reaction time, I am told to flash the car’s lights whenever a red bar appears on the screens in front of me. 

When speaking hands-free, my reaction times were markedly slower than when I drove the simulator with no distractions at all. 

Next came the challenge to follow the vehicle ahead and to maintain a constant distance between the two cars. When driving with no distractions, I managed a fairly constant gap but while speaking on the hands-free, I yo-yoed back and forth wildly.
As for my ability to steer smoothly through a set of curves, I performed relatively well when compared with the other activities. But despite having both hands firmly on the wheel there was still a deterioration.

How can that be, I ask. Surely speaking hands-free is no different to speaking to another passenger? Nick explains: ‘When you are on the phone, you are expected to respond instantly. But when you have a passenger in the car and you reach a tricky road junction or a difficult situation, you can say “hold on a minute”, and carry on speaking later. When you are on the phone you feel obliged to respond immediately, whatever the circumstances.’

REACTION TIMES: 16pc WORSE
KEEPING A DISTANCE: 10pc WORSE
SWERVE FACTOR: 20pc WORSE


Speaking on a hand-held phone
As well as being illegal, talking on a hand-held mobile phone while behind the wheel is the nation’s most despised driving habit, even more than tailgating.
It’s something I know I have been guilty of in the past — not holding the phone to my ear but holding it in one hand and switching on the handset’s built-in speaker.
For the purposes of the experiment, I start by holding it in the crook of my neck and then switch it to my right hand. Again, Nick remotely runs through the series of questions as I negotiate the ten-minute drive.

Recreation: Tom tested a number of scenarios in a simulator, including a conversation on a hands-free set, which was replicated using an intercom

The data subsequently reveals that my reaction time was 14 per cent slower than when there were no distractions, while in the car-following task, my attention wavered to the extent that the gap I left increased by 24 per cent.

When it came to steering a safe course through the curves, there was a 47 per cent increase in drifting. The results come as no surprise to me — it is abundantly clear to me as I do it that my control of the car has drastically deteriorated.

Oddly, my reaction times were marginally better than with the hands-free phone — I’m not sure why, but maybe I was lulled into a false sense of security on hands-free and didn’t concentrate as well. 

REACTION TIMES: 14pc WORSE
KEEPING A DISTANCE: 24pc WORSE
SWERVE FACTOR: 47pc WORSE


Texting
Using a hand-held phone to text or email while driving is illegal. But it is something that half of all motorists aged 18-24 admit to doing regularly — a worrying statistic given that this age group is already at much higher risk of being involved in a crash.
For this set of tests, I place my phone on my lap while Nick uses the intercom to dictate a number of messages for me to tap in to my phone and then send to him.
Before I send each message, I look at the road ahead in a misguided attempt to reassure myself. But, as everyone knows, there is nothing predictable about traffic — simulated or not. And so it is that I have my near-miss with the lorry.

Prevalent: Half of motorists between the ages of 18 and 24 admit to texting or emailing from their mobile phone while driving

These results are the worst of the lot. My reaction times are 25 per cent worse than they were with no distractions and when it comes to following a car at a constant distance, I open up the biggest gap of all but then, when it slows down, end up getting closer to it than in any other of the tests. As for following a curved road, the 85 per cent deterioration in my control says it all.

‘When texting, drivers are distracted by taking their hand off the wheel, by trying to read small text on the display, and by thinking about what to write,’ says Nick.
‘This combination resulted in the impairments to reaction time and vehicle control that place the driver at a greater risk than having consumed alcohol to the legal limit.’

REACTION TIMES: 25pc WORSE
KEEPING A DISTANCE: 40pc WORSE
SWERVE FACTOR: 85pc WORSE


Eating a sandwich
Eating, drinking and smoking while driving are not illegal activities in the UK but drivers can be charged with careless driving if police believe they are not in control of their vehicle as a result.

I arm myself with an M&S baguette and settle back behind the wheel of the driving simulator. Obviously the problem with eating a BLT at the wheel is that it involves one of your hands. It also takes your eyes from the road as you instinctively tend to look at what you are about to put into your mouth. 

Diverting concentration: Eating requires two hands, and drivers will often look at what they are about to put in their mouth, meaning their eyes are off the road

But I’m still shocked to discover that my meal-on-the-go has the second worst effect on my reaction times (only texting is worse) and the second biggest increase in difficulty following the car in front.

When it comes to controlling the vehicle through the curves, I don’t fare so badly — but that’s probably because I polish off the sandwich before I reach the end of the course.

REACTION TIMES: 19pc WORSE
KEEPING A DISTANCE: 27 pc WORSE
SWERVE FACTOR: 37pc WORSE


After alcohol 

For obvious reasons, this is the final test of the day and to get me over the UK drink-drive limit — a blood alcohol level of 80mg alcohol per 100ml blood — Nick calculates how much I need to drink in relation to my height and weight. I plump for wine and am presented with a couple of medium glasses.

After 15 minutes to allow the booze to enter my system, I’m back behind the wheel. By this time I’m infused by a warm glow and feeling pretty confident about my ability to handle the vehicle. Unfortunately, the results indicate that I am decidedly over-confident.

While alcohol has the least effect on my reaction time — 8 per cent slower — when it comes to the car-following task, it is the only occasion when I reduce the average distance to the car in front.

In the real world this could, of course, cause problems if said car suddenly slows down or stops. 

Meanwhile, my ability to negotiate the curved stretch of road safely deteriorates dramatically — I record the second worst result of all. It shows how dangerous alcohol can be — and a relatively small amount at that. As instructed by Nick, I had travelled to the lab by train and taxi. And I go home the same way.

REACTION TIMES: 8pc WORSE
KEEPING A  DISTANCE: 19pc WORSE
SWERVE FACTOR: 74pc WORSE 


The final verdict
There’s no doubt the number of people using phones as they drive is on the increase — just look around next time you’re on the road. 

Modern technology means we are now supposed to be contactable 24 hours a day, even when we are on the move. So when you get a text or an email during a car journey, there is a compulsion to read it — and to reply. We all know we shouldn’t, but sometimes the urge is irresistible.

But this experience has taught me that while many might assume drink-driving is as bad as it gets, using a mobile can be even more deadly: while drinking dulled my reaction times 8 per cent, texting slowed them by 25 per cent.

Damning verdict: The number of people using their phones on the road is on the up - making the roads a more dangerous place to be

To put that into context, if I was travelling at 70mph, I would have travelled 8.5 metres further before hitting the brakes in response to a problem than if I wasn’t distracted. That’s more than two car lengths.

When it came to keeping a safe distance between my car and that in front, again, texting was the most disruptive. But most shocking of all was the way mobile use affected my ability to keep my car safely in the middle of a lane as I negotiated a series of gentle bends at 40mph.

When driving while texting my performance deteriorated by 85 per cent, massively increasing the risk of my car mounting a kerb and hitting a pedestrian or drifting into the path of oncoming traffic.

That compared with a 74 per cent deterioration when under the influence, 47 per cent when holding the phone to make a call, 37 per cent when eating a sandwich and 20 per cent when making a call hands free.
Having seen in black and white how dangerous a driver I become when I have a phone in my hand, I would never do it again

UK's first left-hand driving school launches as a QUARTER of Brits admit they are too scared to get behind the wheel abroad

  • Foreign road signs and roundabouts baffle Brits abroad the most
  • Skyscanner is teaming up with instructors to offer the free course
  • 24% of Brits said they would prefer their partners to drive abroad

The UK’s first left-hand driving school has launched after it’s revealed more than a quarter of holidaymakers are afraid to drive abroad.
The course, to be held in Brixton, London, includes familiarisation with foreign road signs and roundabouts to build Brits’ confidence of taking a road trip while away.
Skyscanner is teaming up with driving instructors to offer free classes to travellers looking for practice and advice before getting behind the wheel overseas.

Nervous drivers: A quarter of Brits say they are not confident to get behind the wheel while on holiday

BRITS' TOP 5 FEARS WHEN DRIVING ABROAD...

1. Not recognising road signs
2. Getting lost
3. Going around roundabouts
4. Trying to navigate
5. Driving on the other side of road

The move comes after research revealed 27 per cent of Brits admitted to being afraid of driving on the opposite side of the road. 
The survey of 1,084 adults also showed 36 per cent admit they don't research driving laws before driving abroad and 24 per cent would prefer their partners to drive.
Skyscanner's Mary Porter said: ‘With two-thirds of the world's countries driving on the right-hand side of the road we wanted to give British holidaymakers the confidence they need to drive overseas. 
‘Rules and regulations vary from country to country so we've also published a guide to provide some clarity for drivers including top tips on driving on the opposite side of the road. 
 
‘There is so much to discover off the beaten track so we hope people make the most of it without the fear of driving abroad.’
Unfamiliar signs: Not understanding road signs is a top fear for Brits driving abroad


The guide includes a list of national speed limits for UK's most popular holiday destinations and also a list of unusual road signs they may come across as this is cited as the most fearful part of driving overseas.
There are also top tips on how to drive on the right as well as a list of some of the more unusual driving laws from across the globe.
Classes will run on Saturday, July 12 in Brixton, London and are subject to availability.
