The City of Grand Prairie prohibits commercial truck traffic from using Sunnyvale Rd between Great Southwest Pkwy on the west and N Carrier Pkwy on the east (Referencing the following map of all the strictly prohibited commercial truck routes in northern Grand Prairie, Texas: https://www.grandprairiepolice.org/About-Us/Special-Operations-Bureau/Approved-Truck-Routes). When Grand Prairie police officers pull truck drivers over, the drivers are often unaware that their GPS navigation is routing them onto roads that commercial trucks are not allowed to use.
