From 1st.January 20011,if there is no record on the MID (motor insuranceicon Database) showing a vehicle is insured,which has not been declared as off road by a Sorn,the registered keeper will recieve a warning letter advising of a fine,prosecution,or clamping.

All vehicles that are not registered by SORN -even if they are not being used are included.

Vehicles that are Sorn registered remain unaffected,and there remains no requirements to insure the vehicle.
