With the clocks going back on Saturday night the police have launched a winter road safety campaign across Norfolk and Suffolk.
They say collision rates tend to increase at this time of year so they are warning drivers to be prepared for the change in conditions as the clocks go back.
Officers have been carrying out roadside checks since Monday focusing on defect offences involving lights, tyres, windscreens and screen wash and anything else which may impact on the roadworthiness of a vehicle.
The aim is educate drivers about the risks of driving with defective vehicles while also enforcing offences where appropriate. The operation will run in both counties until November 2.
Chief Inspector Chris Spinks, head of the joint roads policing unit, 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.
“It is also important to make sure your vehicle is fit for winter conditions; make sure lights and windscreen wipers are working, that your tyres have sufficient tread and regularly top up the windscreen wash.”
Drivers will be dealt with by way of verbal warnings and vehicle defect rectification notices while in more serious cases police have the power to seize dangerous vehicles at the roadside.
