A Truck Hit My Car :( will it be written off?

[WATAJK]

soo...why did you merge inbetween a semi trailer and another car. dont you know how long it takes a truck to stop.

This.
Not having a go at you OP but i drive trucks for work and i can't stand it when people go infront of me to gain one spot infront just to see how quick they can move up in line...
What you must be aware of... A semi isn't going to stop for you always.

By the way, i just remembered, you better hope he didn't film you, most truckies now have camera's recording constantly whilst there driving to show stupid antics of other drivers and to show how they aren't at fault and that it's generally a driver who has cut them off.
So if you are telling the truth which im assuming you are, you should be fine but if your pulling strings here, you'll get torn a massive new a-hole if he has caught what you've done on camera.

Hoping the best for you mate.

the issue Androo's talking about is you not being covered @ all because you're not entitled to drive your car with the supposed modifications you have.

But if he's not at fault then a claim should be processed regardless because insurance companies (when third party and not at fault) will not look for things to void his insurance as he wasn't the one who caused the accident (assuming).
They will be assessing to see at first if they can void the truckies insurance if he has an unroadworthy truck etc.

I do agree on the matter that if he has heavily modified his car, regardless, full comprehensive is a must.
Each to there own, i originally didn't have full comprehensive in my first year of ownership of my DC5 but now have had it for 2 years.
You do feel alot more comfortable driving.

Feel free to say other wise.
