Rollover Accidents: 

When a vehicle turns over on its roof or side the car accident is considered a rollover. 

Rollover accidents often involve only a single vehicle and the error of the driver of that vehicle. However, in some cases, rollover accidents may result not from driver error, but external factors. For example, if a rollover accident results from a serious problem in the vehicle’s construction, the vehicle manufacturer could bear liability for the accident. On the other hand, if the rollover collision occurs due to driver error, the driver that caused the accident may bear liability. 

Hydroplane: 

Hydroplaning (also referred to as Aquaplaning) occurs when too much water gets between the road and the tires of a vehicle, causing the tires to lose traction. Drivers often lose control if a vehicle hydroplanes, which is why it often results in a collision with another vehicle or object. Generally, hydroplaning accidents occur during heavy rainfall, but snow can also cause hydroplaning. 

Rear Ended: 

A rear-end collision occurs when a vehicle crashes into the one in front of it. Common factors contributing to rear-end collisions include driver inattention or distraction, tailgating, panic stops, brake checking and reduced traction due to wet weather or worn pavement. 

Brake Checking:  

Brake Checking is a maneuver in which a driver intentionally hits the brakes, often forcing the following driver to also brake or take evasive action. It generally happens in a road rage or aggressive driving incident and is not an approved driving maneuver . It could also be a means of committing insurance fraud.  

SR-22 Insurance :  

An SR-22 is a certification that is required by some state Department of Motor Vehicles (DMV) as proof that a driver has the minimum liability insurance required by law. The SR-22 is filed by an insurance company and verifies to the DMV that the driver has the required insurance coverage. 

So, having an SR-22 does not necessarily mean the person has auto insurance, but it certifies that the person does have the required minimum auto liability insurance coverage. The SR-22 serves as a sort of guarantee to the state that the driver is financially responsible and able to cover damages caused by an accident. 

The requirement for SR-22 is usually triggered in cases where a driver is considered high-risk. For example, it might be required if a driver has multiple DUI's or if their license has been suspended or revoked due to multiple violations. In these cases, it is a condition for the driver to get their license back and to keep it. They are typically required to maintain the SR-22 certificate and maintain the insurance coverage for a period of three years.
