The Chino Hills Police Department and Brea Police Department will begin enforcement of new truck restrictions prohibiting vehicles with more than four axles from traveling through Carbon Canyon Road (SR-142) on Thursday, May 30, following the installation of new traffic signs. This enforcement initiative aims to enhance commuter and traffic safety along Carbon Canyon Road, by restricting the passage of large semi-trucks and other similar vehicles over four axles through the narrow S-curves.
Effective May 30, vehicles with more than four axles will be prohibited from traveling through Carbon Canyon Road as an alternative route to regional freeways such as California State Routes 57, 60, and 91. Signs will be installed to alert drivers before entering Carbon Canyon so they may consider an alternate freeway route. While some trucks may continue to disregard signage, putting safety at risk as they cannot be turned around safely once they enter the Canyon, the City is committed to holding the violators accountable.
Vehicles over four axles are permitted in cases where their presence is necessary for residents who reside in Carbon Canyon and their visitors with a destination in the canyon, for the provision of goods or services to Carbon Canyon residents, or when directly related to City business. Violators will be subject to fines enforced by the Chino Hills Police Department on the San Bernardino County side and by the Brea Police Department on the Orange County side of the canyon.
For questions regarding the new truck restrictions along Carbon Canyon Road, please contact the Brea Police Department at (714) 990-7625.
