Rear end collisions are quite common, and it is often presumed that the rear driver is always at fault. The presumption can be overcome in certain circumstances. Here’s 3 exceptions to the rule...
1. In a sudden and unexpected stop in a place where the driver cannot reasonably be expected, such as abrupt lane changes.
2. Mechanical failure, for instance blown tires, failed brakes or steering that cause the rear driver to collide with the lead driver.
3. When the lead drivers vehicle is illegally stopped.
