I’m curious here, but what happens if you don’t declare modifications? Nothing major like a turbo or supercharger.
Will they “tear up” or void the insurance contact entirely, or just not pay out the cost of modifications?
I have heard that the modifications must have contributed to the accident, but then again I hear/ read so many other opinions?
Because if that is the case, how would a P-plate drive with basic modifications be covered by insurance since performance enhancing modifications are illegal?
Only a fool wouldn’t declare everything to the insurance company. They aren’t in the business of paying out, they are in the business of collecting premiums and
not paying out.
Best to not give them an excuse to not pay out in the first place. Nearly all insurance PDSs will say that modifications can void your insurance entirely so you’re running a big risk by not telling them everything that you know is modified. There’s no laws determining what gets paid out and what doesn’t, it’s up to the discretion of the insurance company via their PDS.
Its possible that if you bought a car secondhand and it had pre existing modifications that aren’t visible or otherwise obvious (say a camshaft) you could plead ignorance if it was ever picked up.
It probably wouldn’t be picked up in the event of a claim unless the insurance company has a compelling reason to do a full investigation, which becomes more likely the higher the value of the claim, leaving you on the hook when you definitely want them to pay out.
A crash with say a Bugatti Veyron (or many other expensive cars or infrastructure) could easily leave you bankrupt so best not to give your insurance company any excuse to deny the claim.
