Blow & Go ignition interlock
Common nickname for interlock devices, also used as a brand name by some local installers.
What Blow & Go costs
Blow & Go does not publish a single national price, and quotes vary by state and by the center doing the install. We are collecting confirmed quotes and will publish them here with the date each one was checked — not before.
We cannot verify Blow & Go against any state list
This name does not appear in our index of installation addresses, and we have not found it on a state register of approved vendors. That does not make it fake — small installers work under a manufacturer’s approval, and some names in this trade are simply nicknames for the device itself. It does mean the claim has to be checked before you pay anyone.
The check takes a minute: open your state’s own register and look for the company. If it is not there, the installation will not count towards your term, whatever the shop tells you.

Not every state publishes a register we could open and read; these ten do. If yours is missing, the licensing agency named on your court order is the place to ask, and the answer is worth getting in writing.
Compare before you commit
Providers rarely differ enough on the device to matter. The difference you feel is the monthly fee, the lockout policy, and how far you drive every 30 to 60 days for a calibration.
