# What is anti-theft discount?

> An anti-theft discount is a premium reduction an insurer may offer for an eligible factory-installed or approved vehicle security device.

Glossary date: July 6, 2026.

## How it works

Qualifying equipment and affected coverages vary. A device may reduce the comprehensive premium without changing liability or collision cost.

## Example

A vehicle has a qualifying tracking and recovery system. The insurer applies a discount to the coverage associated with theft risk.

## Why it matters

The advertised percentage may apply to only a small part of the total premium.

## What to check on your policy

Confirm the device code, proof required, affected coverage, discount amount, and whether the insurer already included it.

Coverage, definitions, limits, and legal requirements vary by policy and state. Your declarations page and policy forms control your coverage.
