Mobile telephone use as a major road safety issue has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. A range of studies conclude that the use of a mobile phone while driving distracts the driver and causes various changes in driving behaviour that negatively affect traffic safety. Driver reaction times are 30% slower when telephoning while driving than driving with BAC levels of 80mg/100ml and 50% slower than under normal driving conditions. pdf5
