About

Built for the people who keep America moving.

Why we built this.

We talked to a lot of owner-operators and small fleet owners. The same story kept coming up: the day after their USDOT number went live, their phone started ringing — and it never stopped. Insurance sales, factoring, lead-list spam, fake “DOT compliance” robocalls. Every day, for years.

Existing call-blocker apps didn't work because they couldn't tell the difference between a real load and a spam call. DOT inspectors got blocked. 911 callbacks went to voicemail. Real brokers gave up after one ring. The cure was worse than the disease.

So we built a shield that knows what a real motor-carrier business needs to receive and what it doesn't. The safety allowlist is always on. The brokers and shippers you've worked with always get through. The cold callers do not.

How we stay legal in all 50 states.

TCPA-compliant

Express consent baseline. No autodial without opt-in. Standard 10-DLC registration on every shield number.

CAN-SPAM compliant

Honest “from” lines. Real physical address in every email. One-click unsubscribe enforced.

CA ARL one-click cancel

California residents can cancel as easily as they signed up. We extend that to every state on principle.

FMCSA addendum

Our service terms include an explicit addendum acknowledging FMCSA reporting obligations and the always-on safety allowlist.
