JB is very correct - we rarely take any notice of 3 points for speeding (assuming itis the �60 fine and not a court assigned fine).
The only convictions that realy make any difference if undisclosed are:
DR10 and the rest, MS90 (failure to disclose the driver), UT (unauthorised taking), IN anyhthing.
However, individual circumstances are taken into account, and all insurers have different rating factors.
If the undisclosed claim or points would only mean an increase in premium of a few quid, it will have no effect. If it increased the premium over a certain percentage (I think it's something like 60% for us), then the policy will be voided from incpetion - ie no insurance for you naughtly person.
Norman, 3 points is highly unlikely to make us not pay the claim - this is up there with the myth that no road tax voids your insurance
