§ 60-450 Opinion and specific instances of behavior to prove habit or custom.

Here's a plain English summary of this rule:

This rule deals with how someone can prove that a person or business has a habit or regular way of doing things. If you want to show that someone usually acts a certain way, you can use two types of evidence.

First, a witness can give their opinion about the person's habit or custom. For example, someone who knows a person well could say "he always locks his car doors" based on their overall impression.

Second, you can bring up specific past examples of the behavior. But there's a catch. You need enough examples to actually show a pattern. One or two instances usually won't cut it. The court needs to see enough repeated behavior to believe it's a true habit, not just something that happened once or twice by chance.
