Police have launched a new road safety campaign in Norfolk and Suffolk to coincide with the clocks being put back an hour this weekend.
British Summer Time ends at 2am on Sunday and, though that means an extra hour in bed for many, the switch also tends to see a rise in the number of crashes.
Today, police in the two counties began carrying out roadside checks on vehicles across the county in a bid to get their safety message across.
Chief Insp Chris Spinks, the counties’ head of roads policing, said: “The rise in collisions at this time of year can be down to a number of factors including lighting defects, poorer weather conditions and people not used to driving in the dark.
“We know that one of the main causes of collisions at this time of year is drivers not looking properly and this operation is about raising awareness among motorists to prevent these incidents from happening.
“These may seem minor issues to some drivers but if you drive a car with one headlight out you are effectively reducing your visibility by half and the chances of being seen.
“I would encourage drivers to watch their speed, keep a good distance between you and the car in front, and take time to look out for other road users, cyclists and pedestrians.”
Norfolk police and crime commissioner Stephen Bett added: “This operation has my full support.
“I would urge motorists to take heed of the police advice, to look after their vehicles and take extra care as the nights draw in.”
The campaign will focus on issues relating to lights, tyres, windscreens and screen wash and other areas that may affect whether a vehicle is roadworthy or not.
Although most issues will be dealt with through verbal warnings or a vehicle defect rectification notice, which gives drivers 14 days to have issues repaired, vehicles can be seized if they are particularly unsafe.
The operation will continue until next Sunday, November 1.
