For that reason, if you or someone you know has been injured or suffered property damage in a car accident, whether you/they are being blamed for the accident or not, it is wise to immediately contact an attorney specializing in personal injury law.
If one of the drivers is issued a citation for speeding, running a light, or another violation, he or she will most likely be primarily at fault, and carry the heaviest burden of the resulting liability.
The driver that does not change lanes has an obligation to pay attention to the movement of the other cars and drive a safe speed for the conditions. When a driver fails to do these things, they can have some fault for an accident when another driver changes lanes.
Most of the time drivers that are merging during an accident are at fault because the other driver has the right of way. The merging driver is supposed to yield the right of way. When they fail to do so they are at fault.
Some drivers will not take the time to check their blind spots. Other drivers will not use a turn signal before changing lanes. Of course, none of this means the driver that does not change lanes has no fault. Sometimes the driver that does not change lanes can have some fault, too.
