Liability for New Hampshire Rollover Collisions
Drivers in New Hampshire have a legal obligation to use reasonable care and follow all traffic laws to reduce the risk that they will be involved in a collision. Pursuant to New Hampshire RSA 265:60, no vehicle shall be driven at a speed faster than is reasonable and prudent given the prevailing road conditions. Drivers are also required to remain as practicable within a single lane of traffic and avoid changing lanes unless that movement can be done with safety. Courts will take into consideration numerous factors when determining liability for any motor vehicle collision.
- They will consider the speed of all vehicles involved and the visibility conditions at the time of the crash.
- They will look at whether or not an unsafe lane movement may have contributed to the sequence of events prior to a crash.
- They will review whether distraction, impairment, or some other condition affected a person’s ability to operate their vehicle safely.
- They will examine the physical condition of the vehicles involved to determine whether or not a mechanical issue could’ve played a role in the crash.
If a driver allows their vehicle to drift and collide with a fixed object, this could serve as evidence of negligence. These types of collisions are nearly always the results of one or more safety violations. Depending on the unique facts of a case, there may be several sources of liability for any particular collision. This includes the manufacturer of any vehicle involved in a rollover collision. If a rollover accident causes the roof of a vehicle to cave in, this could create the basis of a product liability claim. Car manufacturers must take certain precautions to prevent these types of issues with their vehicle.
What to Do After New Hampshire Rollover Collisions
Rollover collisions are among the most dangerous accidents that a person can be involved in. They come with the serious risk that the driver or other occupants could potentially become ejected from the vehicle. According to one study by the NHTSA, 6,250 passengers were killed in rollover car accidents in 2024 alone. Many more sustained serious injuries. It is important that victims take certain actions to protect their health and legal rights after any rollover collision.
- The police should be called to the scene as early as possible so that they can begin documenting relevant evidence.
- Victims should seek medical treatment for their injuries as early as possible. Failing to seek medical treatment after an accident can have multiple negative health and legal consequences.
- Traffic camera footage that may have captured the collision should be sought as early as possible before it is recorded over or lost.
- Injury victims should carefully consider their legal options with a team experienced in accident reconstruction and negligence claims.
Being seriously injured in a car accident is often one of the most difficult things that most people will go through in their lives. An injury can impair a person’s ability to work or even perform ordinary tasks. To make matters worse, negligent drivers and their insurance providers are not likely to accept responsibility when someone is injured in a collision. Victims are able to pursue some measure of accountability and justice through a personal injury claim. Damages in a personal injury claim can help cover lost wages, medical bills, and pain and suffering.
