Program Overview
What is Green Light?
It´s a way for Oregon truckers to save the time and money they waste stopping at weigh stations. It´s a truck weigh station "preclearance" system that´s just like systems you´ll find in many other states. But the Oregon Green Light system is better than most — it´s free!
Green Light uses weigh-in-motion scales and transponder readers to screen trucks as they approach a weigh station. It increases a station’s capacity without physically expanding the facility, providing efficiencies for state regulators. But the trucking industry enjoys even more tangible benefits because operating a heavy truck is estimated to cost $1.24 per minute and stopping at a weigh station can take five minutes. Since transponder-equipped trucks have been precleared to pass Oregon weigh stations a total of 6,291,900 times in the past seven years, trucking companies have saved 524,000 hours of travel time and $39 million in operating costs.

Innovation: What is new or cutting edge about Green Light?
Scales in the roadway weigh trucks in-motion at high speed as they approach the station while automatic vehicle identification devices look for signals from a palm-size transponder mounted inside truck windshields. The transponder contains only a 10-digit number that is used to identify the carrier and specific truck. A computer takes in all the information, verifies truck size and weight, checks the carrier´s registration and safety records, and sends a green light signal back to the transponder if the truck is "good to go" past the station.
Green Light uses the Mark IV transponder, one of the most common truck transponders in use today. It works in all states participating in the North American Preclearance and Safety System – NORPASS - weigh station preclearance system, and it is capable of working in all states participating in the HELP PrePass system. But users must enroll and agree to certain terms and conditions to use those other states´ systems. Users must also pay for preclearance in PrePass states. Until 2003, Green Light was using the Raytheon-Delco Type II+ model transponder.
