What constitute handphone driving?
To ensure that only drivers who blatantly disregard the safety of other road users by using their mobile phone while driving, 3 clear conditions were stipulated. For the offence of handphone driving to stand, ALL the following 3 conditions must be fulfilled:
(a) the vehicle is in motion; and
(b) the driver is holding on to the handphone with one hand; and
(c) the driver is communicating with any person with that handphone.
[Para 2(c) includes making phone calls, paging for someone, receiving a call by pressing the keypad, reading, writing or sending of SMS.]
The purpose of setting the 3 conditions is to ensure that drivers who have no intention to commit handphone driving will not be caught by ambiguous rules. For example, a driver who simply holds a mobile phone but is not using it to communicate while driving will not have committed an offence of handphone driving. However if by doing so, the driver loses attention on the roads and fails to maintain proper control of his vehicle, he will still have committed an offence of driving without due care or reasonable consideration.
Similarly, the spirit of the law is such that the driver who uses his handphone is only a menace to other road users if his vehicle is moving. As such, drivers who use their handphone while the vehicle is stationary should not be caught by this rule.
In short, Traffic Police do not take action against motorists for handphone driving simply because there is a handphone on the passenger seat or beside the driver. Traffic Police will only take actions when our observations show that all the three conditions for the offence of handphone driving are concurrently present.
