The Illinois Department of Transportation's adoption of PrePass truck technology almost 10 years ago has reduced greenhouse gas and related emissions by more than 17,000 metric tons.


Based on the program's projected success, PrePass is anticipated to cut emissions during the next decade by an estimated 29,000 metric tons, the equivalent of eliminating all emissions from more than 525 cars per year.

PrePass is a technology enabling qualified motor carriers to comply electronically with state weight, safety and credential requirements at highway speeds. Participation is strictly voluntary and carrier eligibility is subject to strict safety qualifications.

Since its deployment in Illinois, PrePass has saved carriers more than $103 million in operational costs, including fuel savings of more than 7.7 million gallons. By enabling enforcement personnel to concentrate on those trucks most likely to be noncompliant, and by reducing lane-changing and congestion around weigh stations, PrePass also makes highways safer for all motorists.

Based on EPA engine idle reduction estimates, since its inception in 1995, PrePass has reduced emissions by more than 265,000 metric tons nationwide. Through PrePassPlus, which provides commercial motor carriers with seamless interoperability with the I-Pass/E-ZPass electronic toll collection systems, significant additional fuel, time and emission reductions have been realized.

PrePass is now operational at 281 sites in 28 states: Alabama, Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Maryland, Mississippi, Missouri, Montana, Nebraska, New Mexico, Ohio, Oklahoma, South Carolina, Tennessee, Utah, Virginia, West Virginia, Wisconsin and Wyoming. PrePass will become operational in Delaware later this year.

Nearly 450,000 trucks have voluntarily enrolled in PrePass to take advantage of the time and money saving benefits.
