A number of commercial vehicles were taken off the road in Stephenville following a highway enforcement checkpoint this week.
On Tuesday, six commercial vehicles were inspected and nine defects were found. Police say four of the six vehicles were removed from service.
One driver was ticketed under the Highway Traffic Act for operating an unregistered vehicle, and two others were ticketed for failing to produce a daily logbook.
Two drivers were also required to report to the Motor Vehicle Division to ensure they have the correct weight category registration for their vehicles.
