Hit-and-run OCD involves persistent fears about accidentally injuring or killing someone while driving and not realizing it. Although the fear centers on driving, the core issue is often a need for certainty and repeated attempts to determine whether harm occurred.

Many people with obsessive-compulsive disorder (OCD) experience intrusive thoughts about harming themselves or other people.

These thoughts are often deeply unwanted, frightening, and emotionally devastating. People may become terrified that the thoughts mean something dangerous about who they are or what they might do.
