Electronic Message Board/Variable Message Signs #
Drivewyze users can continue to follow in-cab messages when approaching sites where there are roadside message boards. Except in states where restrictions exist (Wisconsin and Idaho). In these two states, please follow the message boards.
Using Multiple Bypass Services #
A driver that operates both Drivewyze and another transponder-based bypass service may visit sites where both bypass programs are in operation at the same time. If you are using multiple bypass programs, you may receive conflicting messages when approaching a weigh station that supports both programs. In this case, if either Drivewyze or the other bypass service indicates you should pull in into the site, you must pull in if the station is open. You can only legally bypass if both programs indicate you should bypass. For this reason, it is important for drivers and carriers let Drivewyze know if they intend to operate Drivewyze alongside a second bypass service, so that drivers do not see conflicting commands from both services. If there’s ever a situation where Drivewyze and the transponder show conflicting messages, please be aware that any pull-in commands from either service MUST be obeyed. Failure to do so may result in a citation by enforcement agencies. If you haven’t told Drivewyze that you’re using a secondary bypass program, please contact support@drivewyze.com or call 1-888-988-1590. Our team will be happy to assist you.
