Tayside Police has warned motorists ignorance is not an excuse as they target uninsured and unlicensed drivers in the region.
Constable Malcolm Kinross told drivers it is up to them to ensure their documentation is up to date as police target those driving illegally.
Although some drivers may not know they are contravening traffic laws, PC Kinross said those who believe they can ignore the problem can expect no sympathy.
He said: ”Ignorance is definitely not an excuse. That is something of a clich, but if we stop you on the road and you are not insured or licensed properly then you will be fined £200 and have six points added to your licence.
”That in some ways is the best-case scenario, because the worst thing that could happen is that a person is involved in an accident without insurance.
”We are here to get the message across that people need to keep their house in order.”
Since the introduction of new legislation in 2006, PC Kinross said that almost 4,000 vehicles had been seized by Tayside Police from drivers who were unlicensed or uninsured.
He added that around a third of these had not been claimed by their owners afterwards.Ignorance no excuseNew photo-card driving licences require renewal every 10 years or can be declared invalid, another potential problem for anybody pulled over by police.
PC Kinross continued: ”If we stop a vehicle that is not licensed correctly or insured then we have the power to seize the vehicle.
”To get the vehicle back the driver then has to prove that they are suitably licensed and insured.
”They also have to pay a release fee and £20 storage for every day we have the vehicle.”
The nationwide clampdown has been organised by the Association of Chief Police Officers in Scotland and will last until 7am on Friday.
Other offences being targeted include speeding, failure to wear seat belts and the use of mobile phones behind the wheel.
