Does turning off safety systems invalidate insurance in the event of an accident?

My wife has a Citroen C4 Grand Picasso which has various safety systems fitted as standard. My wife turns off the Lane Departure Warning System as she feels its not required. Does turning off any of these systems invalidate the insurance in the event of an accident?

No, it doesn't because you should not need to be reliant upon them. They are "advanced driver assistance systems". They are there to assist not replace. The onus is always on the driver to ensure it is safe to carry out a manoeuvre. An insurer would have to prove that having a system turned off "directly contributed or caused the accident" to attempt to invalidate a claim, and it never could. There could have been other factors that equally contributed to it.
