Behind-the-wheel mobile phone crackdown comes to an endpublished at 08:59 Greenwich Mean Time 13 March 2017
The message is getting through to drivers to not use their mobile phone while they're behind the wheel, according to Humberside Police.
The force has just finished a week-long campaign on the region's roads where it used an unmarked lorry to spot offenders.
Officers caught fewer people using their phones than in previous operations and say the recent introduction of tougher penalties may be behind the fall.
PC Barry Gardner says: "Maybe it's the fact the penalty has doubled - the £200 and six points.
"Let's hope that whatever the reason, it continues to work," he adds.
