To all those saying you should not inform the DVLA> If you had a serious accident, even if not your fault, the police are allowed to take blood tests for drugs (if they suspect drugs and you refuse, you get banged up), if they don't suspect and you refuse - you can still get done. And anti-convulsants (i.e Keppra) will show up. They also have the power to check medical records (without a warrant).
If you don't tell the DVLA, you may as well not bother with insurance, because you won't be insured either.
Go and drive. Kill a kid and do 10 years in nick. Easy.
