The MNTC has started to apprehend motorists violating the 100kph maximum speed limit on the closed-system portion of the NLEX.

They would apprehend the said motorist upon approaching the Bocaue tollplaza (going to Manila).

This cannot still be implemented in the open-system portion since there exits of the said portion doesn't have a toll gate.

How do they do this? There are imbedded and fixed speed traps along the stretch of the NLEX. Once you "trigger" the said traps, a camera (placed around 40 ft overhead) will take your license plate numbers.
