A more thorough explanation:

Definition: Regular use refers to the usual, normal, or customary use of something, as opposed to occasional, special, or incidental use.

Example: In automobile insurance policies, regular use is defined as the primary use of a vehicle, as opposed to occasional or incidental use. For example, if a person uses their car to commute to work every day, that is considered regular use. However, if they only use their car once a month to run errands, that is considered occasional use.

This example illustrates how regular use is distinguished from occasional or incidental use, and how it is used in insurance policies to determine coverage.
