§ 1104 Character Evidence Exclusion

• •You can't use someone's past behavior to guess if they were careful or skilled in a specific situation.
• •This rule stops people from saying things like 'He's always reckless, so he must have caused the accident.'
• •There are some exceptions, but usually, only what happened in that one moment matters.

A person gets into a car crash, and the other driver says, 'He’s always driving too fast, so it’s his fault!'

The court won’t let the other driver use the person’s past driving to prove he was reckless this time. Only what happened during this crash counts.
