Smartphones provide serious threat to driving safety

Research into the risks posed by the use of smartphones by drivers has revealed extremely worrying results. An international study into this field has shown that using cellphones to send texts while at the wheel can deliver significant risks for vehicle occupants as well as others. The study has shown that sending texts while at the wheel presents a similar safety risk to being 25% over the legal limit for alcohol in the bloodstream. In addition the study has shown that using hands-free telephone technology

Research into the risks posed by the use of smartphones by drivers has revealed extremely worrying results. An international study into this field has shown that using cellphones to send texts while at the wheel can deliver significant risks for vehicle occupants as well as others. The study has shown that sending texts while at the wheel presents a similar safety risk to being 25% over the legal limit for alcohol in the bloodstream. In addition the study has shown that using hands-free telephone technology may not reduce risks, with the intensity and complexity of the conversation being a critical factor. The study has been carried out jointly by a number of universities and institutes. These include the University of Barcelona and from Australia; Wollongong University, Victoria University and Swinburne University of Technology.

The research compared how mobile phone impacted on driving ability against known data on alcohol use by those behind the wheel. The researcher assessed a group of drivers under laboratory conditions using simulation technology. Factors such as excess speed, reaction times for braking, changes in speed and lane changes were monitored under the tests, with drivers being assessed when not using a phone, using a hand-held device to send texts and using a hands-free system for conversation. The research also compared the effects of a simple conversation with that of a more complex discussion. A further step was to provide the test subjects with controlled quantities of alcohol to meet three set blood alcohol levels, and then carry out a series of tasks using a driving simulator. The data revealed that driving ability dropped significantly when the test subjects were using cellphones to send texts or to carry on complex conversations.

What the study shows is that the human brain does have limitations with regard to multi-tasking and this applies to both males and females alike. With regard to the hands-free technology, more research will be required to determine the difference between discussions that are involving and require greater concentration than simpler conversations. Attempting construct a legal framework around what type of discussion would be permissible for drivers using hands-free technology may be complex however and it would seem likely that simple bans may be easier to implement.

The issue of distracted driving is a growing problem around the world and this research highlights that a broader understanding of the risks as well as greater enforcement and much tougher penalties are required.

    The US has serious road safety issues that need to be addressed. In 2018, close to 36,600 people were killed in road crashes, according to data from the National Highway Traffic Safety Administration (NHTSA). The fatality rate for 2018 represents a 2.4% drop from 2017. In addition, the road death rate/160 million vehicle km traveled also decreased by 3.4%, from 1.17 in 2017 to 1.13 in 2018. And the NHTSA says it is the lowest fatality rate since 2014. Nearly 36,600 people died on US roadways last year, a

    Police in the US state of Ohio recently found themselves in a high-speed pursuit involving a vehicle taken without its owner’s consent. The chase lasted for around one hour and the vehicle hit speeds of up to 160km/h during the pursuit, which covered a distance of around 72km in all between Cleveland and Milan. Officers managed to box the car in and bring it to a halt, without anyone being injured. The driver was a 10-year-old boy who took his mother’s car, the second time that the lad had done this in just

    New data from the UK reveals key information about road risk factors both across the country and in capital London. A new report reveals that around 68% of pedestrian casualties are adults who are at greatest risk on weekend evenings and after consuming alcohol. Meanwhile another separate study in London reveals that cyclists are not at fault in most crashes in which they are involved.
  • Research shows male drivers more likely to overtake rashly
    July 1, 2013
    A new survey carried out in the UK reveals that male drivers are more likely to risk lives by overtaking blind and speeding on rural roads. As a result male drivers are being urged to be more careful. The survey was carried out jointly by safety body Brake and insurance firm Direct Line. The data reveals that 24% of drivers risk catastrophic head-on crashes by overtaking blind, while 44% admit speeding at over the national speed limit of 96km/h (60mph) on rural roads. Men are much more likely to take these
