many states now use electronic bypass systems (or avi - automatic vehicle identification) to alleviate some of the truck traffic through the weigh station. some of the best known are prepass, norpass and drivewyze. the system may consist of equipment at the weigh station itself, as well as a truck mounted transponder or smartphone, usually placed on the inside of the windshield or on the dashboard. these are similar to transponders used for toll collection. each transponder is directly registered to a specific truck, and contains a unique identification. the registration process propagates information such as carrier name, unit number, and elected gross weight to weigh stations. in addition, the system keeps a basic safety and compliance record for each vehicle. as a truck approaches a weigh station (approximately one mile before), an electronic "reader" on a boom over the freeway reads the information from the truck transponder. it also looks at the safety and compliance record on the database. a display shows the results to the weigh master, including the speed of the vehicle. the weigh master may have the system automatically determine if a truck needs to stop or may override the system. approximately one-half to one full mile after passing under the "reader", the truck will pass under another boom which has an electronic unit to send the transponder a signal. if the safety information is acceptable the truck may receive a green light and can continue without entering the weigh station at all. there are weight detecting devices in the roadway itself. a driver may get a red light. on these occasions, the truck must pull into the weigh station for the normal weigh-in procedure. the most common reason a truck is "redlighted" is a weight problem, or a random check. each time a truck is randomly pulled in, it is noted in the system whether the driver was compliant or not during the check. this affects how often a truck (or different trucks from the same company) are pulled in. for example, a company which is very compliant with the law will probably only have 5% of its trucks "redlighted."
weigh station
on april 19, 2017, a virtual weigh station opened along northbound de 1 south of the interchange with us 13 north of smyrna. this weigh station allows trucks to be weighed at highway speeds; trucks with possible violations are instructed by signs to exit and follow us 13 north to a weigh station in blackbird for additional screening and assessment while trucks with no issues are allowed to remain on de 1. the virtual weigh station was constructed to ensure trucks traveling north through delaware were being weighed after the completion of de 1 in 2003 allowed truck traffic to bypass the weigh station along us 13.
