A more thorough explanation:

Joint negligence refers to the negligence of two or more people who act together to cause an accident. It is different from concurrent negligence, which is the negligence of two or more parties acting independently but causing the same damage.

For example, if two drivers are racing on the highway and cause an accident, they can be held jointly negligent for the damages caused. Another example is if two construction workers fail to properly secure a heavy object and it falls and injures someone, they can be held jointly negligent for the injuries.

Joint negligence means that both parties are responsible for the damages caused and can be held liable for them. It is important to determine joint negligence in cases where multiple parties are involved in an accident or incident.
