Scenario 1 - turn indicators INSURANCE COMPANY: Dear Sir, although you had right of way, the driver of the other vehicle could not see your turn indicator. As your vehicle did not comply with motor vehicle standards, we hereby deny your claim. Scenario 2 - HID Kit POLICE: As a direct result of your vehicle modifications not meeting motor vehicle standards, Mr Blank (oncoming driver) was unable to see the road hazard/bend in sufficient time to respond, resulting in the death of one of the vehicle occupants. These may be severe examples, but once you do a police accident investigation course, you see how such small things can be so bad.
