Somebody you know thinks
this bill is worth your ten minutes.
The BUILD America 250 Act is a 318-section transportation bill. Buried in Title V is Subtitle E, which sets the terms on which self-driving trucks are allowed to run interstate. This site explains it and helps you write to your representative about it, in your own words.
It has no ability to contact anyone: no email server, no fax, no forms submitted on your behalf. It helps you draft a letter. You read it, change whatever you want, and send it yourself, under your own name. That is the whole point: a letter that is actually yours is the only kind worth sending.
Where the bill actually stands
It has not passed the House. It was ordered reported out of committee (amended) on 22 May 2026, 62–2, and it is waiting on a floor vote. That is the window letters are for: before a vote, not after.
One honest complication: the committee amended the text, and that amended version has never been published. Nobody outside the committee has it. So everything on this site describes the bill as introduced on 19 May 2026, and says so on every page. Other House committees may still change these provisions before a vote.
What Subtitle E does
Six sections, 6 of them about autonomous vehicles. Within two years the Secretary of Transportation must issue a performance-based safety standard for self-driving trucks. After that, a manufacturer may run one interstate once it certifies to that standard itself and documents a written “safety case”. For Level 4 and 5 vehicles the manufacturer takes on the driver’s real-time duties, while the section expressly says it does not create, expand or limit anyone’s legal liability.
- Sec. 5401: Definitions
- Sec. 5402: ADS-equipped commercial motor vehicle interstate operation
- Sec. 5403: Review and preemption of State laws and regulations
- Sec. 5404: Regulatory flexibility for safety technologies
- Sec. 5406: National consumer complaint database
- Sec. 5407: Commercial motor vehicle workforce development
A seventh section sits inside Subtitle E and is not about autonomous vehicles at all (Sec. 5405 is about cab-mounted warning beacons). Anyone who tells you Subtitle E has seven AV sections has counted it wrong.
Why a letter, and why yours has to be different
Congressional offices weigh identical form letters as one letter. A thousand copies of the same paragraph is a single data point with a big number next to it. A hundred letters from a hundred drivers, each describing something that actually happened to them, is a hundred data points, and it is much harder to dismiss.
So this tool refuses to produce the same letter twice. It assembles from a bank of human-written passages, then compares every draft against every letter it has ever produced for anyone. If a draft is too close to one that already exists, it throws it away and starts again. If it cannot find something distinct, it tells you so and asks for more of your own experience, which is the honest fix anyway.
No language model writes any of it. There is no model to leave a fingerprint, and no way for the software to invent a claim about the bill. It cannot write sentences at all. It can only choose between ones a person already wrote and checked.
What we do with what you tell us
We keep your account, and the handful of profile facts you enter at signup so you do not have to type them again. We do not keep your letters. What gets stored is a one-way fingerprint of each draft, enough to tell whether the next one is too similar, not enough to reconstruct a word of it. Details on the privacy page.
