Motorists are being urged to ensure their vehicle tyres are fit for the road.

The owners had their details taken, with a call to present their cars for further inspection within seven days, if they fail to do so it becomes a matter for the police.
This type of enforcement will continue around the Island with hefty fines in place for those who continue to ignore warnings.
Director of highways Richard Pearson says there is a very serious reason behind the clampdown (audio):
