Effects of mobile phone use on crash risk: Mobile phone use: Studies suggest that drivers using a mobile phone There are different types of driver distraction, but are approximately four times more likely to be the use of mobile phones while driving is of primary involved in a crash than when a driver does not concern to policy-makers.

Nonetheless, mobile because of the cognitive distraction involved with phone use may be considered as one example of both types of phones. the broader problem of driver distraction. Interventions: Studies from a number of countries suggest that To date, there is little information on the the proportion of drivers using mobile phones effectiveness of interventions to reduce mobile while driving has increased over the past 5–10 phone use while driving. As a result, a number years, ranging from 1% to up to 11% at any of countries are following an approach that has one moment, with the use of hands-free mobile been known to be successful in addressing other phones likely to be higher. In many countries the key risk factors for road traffic injuries, such as in extent of this problem remains unknown, as data increasing seat-belt use, or reducing speed and on mobile phone use is not routinely collected drink-driving.
