According to the Federal Motor Carrier Safety Administration, weigh station bypass systems can save an average of $8.68 and five minutes per bypass. That does not include extra time and money spent should your truck get inspected. Two primary types of technologies are used for weigh station bypassing: Radio Frequency Identification (RFID), which identifies vehicles through windshield-mounted transponders, and Commercial Mobile Radio Services (CMRS), which uses cellular technology for truck identification through mobile phones, tablets and in-cab telematics devices. Here are 6 factors to consider before selecting the weigh station bypass system that's best for your fleet. Not All Bypass Technology Platforms are Equal One of the primary differences between RFID transponders and cellular CMRS is reception – how well signals are transmitted between weigh stations and trucks. RFID transmits and receives signals with almost 100% accuracy. Alternatively, just like your cell phone, CMRS signals can be dropped, affected by terrain, weather, service providers, the type of cellular device or tablet, and the quality of the GPS chip set. Another concern of CMRS is signal latency, or delays in the transmission time between the truck and the station. You don't have to worry about latency when using RFID. That's because RFID transponders have a response time measured in just a few hundredths of a second from the time the truck approaches a weigh station, transmits its credentials and the driver receives P A R T N E R S O L U T I O N S / P R E P A S S 6 Things to Consider When Selecting a Weigh Station Bypass System 1
