Motorists who talk on mobile phones while driving could be stopped by Humberside Police in a bid to increase road safety.
Police say using a mobile impairs driving
The force has launched a month-long campaign targeting phone users on the move.
There is no specific law against using a phone while driving, although the government is considering new legislation.
But officers argue that drivers cannot be in full control of a vehicle if they are driving and talking on a mobile at the same time.
They claim there is growing evidence that the use of phones is a factor in many serious collisions.
During April, Humberside traffic patrols will stop phone-using motorists and warn them of the dangers.
If the driver is considered to be not in proper control of the vehicle they will be given a fixed penalty notice.
