The Driver and Vehicle Licensing Agency (DVLA) has warned motorists over the risks of sharing sensitive documents on the internet.
Putting photos of your driving licence on social media or including shots of your vehicle's registration documents in an online advert can give away private information that fraudsters can exploit.
A driving licence contains many of the key details that can be used to steal people's identities, including full name, date of birth and address.
Your car's log book also includes your name and address, as well as important details about the vehicle such as its registration number and Vehicle Identification Number (VIN).
Criminals can use this information to clone your car, using your car's details to hide the identity of a stolen or salvaged vehicle which can then be either sold on or used for criminal activity, the Press Association explained.
You could then face parking and speeding fines as well as more serious charges if a vehicle using your car's identity is used in a crime.
The DVLA recently offered seven tips to help motorists stay safe online:
1. Only use gov.uk websites when looking for information online or when using DVLA services, so you can be sure the service you're using is legitimate.
2. Watch out for scam emails. The DVLA will never never send emails asking you to confirm your personal details or payment information, so if you receive one, ignore it.
3. Beware of potentially misleading third party websites which charge additional fees for services that are free on gov.uk websites.
4. Look out for websites offering to connect you to the DVLA's contact centre, as they are usually premium rate numbers. When you dial direct, the numbers start with 0300 and are charged at local rates.
5. Don't share images of your driving licence and vehicle documents online, to protect yourself from identity theft.
6. Ignore any text messages about vehicle tax refunds -- these are not genuine.
7. Report any suspected scams to Action Fraud.
