Commute Trip Reduction (CTR) Law and Commuting Resources

The Commute Trip Reduction Law

The CTR Law was adopted in the early 1990s to reduce traffic congestion and improve air quality.  It also helps conserve limited natural resources.  

The CTR Law requires employers with 100 or more full-time, permanent, year-round employees who arrive at work on weekdays between the hours of six and nine in the morning to have programs for their employees supporting and encouraging non-single-occupant-vehicle (non-SOV) commute options. The CTR Law also specifies these CTR-affected employers must: have an employee transportation coordinator (a person who helps educate employees about commute options), submit regular CTR program reports and, every two years, survey employees on their commute choices.

Alternatives to driving alone might include: carpooling and vanpooling, riding the bus or train, walking or bicycling to work, or working a flexible schedule (such as four 10-hour days a week with one day off) or working from home (a.k.a. "teleworking").
