The PrePass app gives drivers the option to bypass weigh stations using mobile devices. PrePass is the only bypass app that provides the flexibility to leverage a bypass transponder or use the PrePass application stand-alone.

PrePass not only saves fleets time, fuel and money, but it helps create greater efficiencies for shippers and supports improved safety for all highway users.

With PrePass, customers select whether to use the PrePass app, the transponder or BOTH. The PrePass app provides coverage to an expanded number of weigh station sites while the transponder provides greater bypass reliability and integration with NORPASS and Oregon Green Light weigh station locations. The transponder also provides the option of adding toll payment services through PrePass Plus.

Jasper Dunbar ,

Very good app for the small operator

Definitely need wyoming, nebraska and iowa in it since you guys already have everything else covered except some strict states like oregon, cali, oklahoma and arizona which who knows hpw long it would take you guys to work something out with them but the ones i have mentioned,the law enforcement from my point of view is pretty liberal when it comes to truckers


Great idea but needs improvement

I like having the ability for the app to display weigh station notifications to my garmin but... I'm already past the prepass readers by the time the app says I'm approaching a scale.
The app needs to have the initial notification at least 1-2 miles before the scale.

I don't know how long this app has been available but other notifications like parking/ rest areas are hit but mostly miss.
I haven't gotten any of the notifications besides scales and some parking/ rest areas.

I don't know if it's just iphones, but the app will not save my login which can be a pain.

Definitely needs work but I really like the idea.

Ok but

When this app came out, I thought it was going to be great. I downloaded the app and signed up. I’m using the app on iOS and the first thing that I found out was the app doesn’t work in the background. This is a no go for me because I use my iPad and or iPhone as a gps too. This means that I have to switch apps every time I come to a scale. So now it’s just another worthless app sitting on my phone not used. If at some point they change this, I might start using it again.

Developer Response ,

Thank you cassiedog for your feedback. If you are using GPS in the foreground and have the Motion app open in the background, the Motion app will send push notifications that will display and provide an audible alert. We wish you safe trucking.
