The devices then wirelessly {{U}} {{U}} 9 {{/U}} {{/U}}data to Progressive on how many miles customers travel, how fast they drive, and other factors. Progressive uses the information to offer policyholders discounts every six months for safe behaviour and, in states where it's allowed by laws, to tack {{U}} {{U}} 10 {{/U}} {{/U}}surcharges for risky driving.
