Driving is a complex task, requiring drivers to use and coordinate a number of skills. Any lapse in concentration increases the risk of the vehicle being involved in a crash.
Using a mobile phone while driving can bring even greater danger to novice drivers as they may experience difficulty in balancing the many demands on their driving - from perceptual, mental and physical tasks. Research has found novice drivers who use a mobile phone spend less time looking at the road ahead. They are also more likely to wander over the road (across traffic lanes) and take longer to notice driving hazards.
A mobile phone can be important in an emergency. If you need to use your mobile phone to call for help, stop and park safely where you will not endanger other road users.
