Together with representatives of the Department of Science and Technology, the LTO-deputized officers of the Southern Tollways recently conducted the re-calibration of the speed and laser guns used at Skyway O&M Corporation (SOMCO), the Manila Toll Expressway Systems, Inc (MATES), and Star Tollway Corporation (STC), operators of the Skyway System, South Luzon Expressway (SLEX) and Star Tollway in Batangas.

The daytime calibration of the RSV2 speed radars and nighttime calibration of TruCam Laser guns were done along SLEX and 6 speed machines for MATES, 3 each for SOMCO and STC, were and calibrated accordingly. Each of the Expressway's minimum speed limits are set to 60 kph for all vehicles. An 80 kph maximum limit is set for trucks and buses and 100 kph maximum for cars or Class 1 vehicles.

The Southern Tollways operators are also boosting their campaign against unsafe and non-roadworthy vehicles. Road safety checkpoints are being set up at the approaches of select entry points of the Skyway System between Makati and Alabang, of SLEX between Alabang and Calamba and of Star Tollway between Sto. Tomas and Batangas City. To enforce this, groups of mechanics and traffic enforcers will inspect vehicles at random or flag down vehicles that present road safety risks. These include unsafe loading, non-working lights and worn out tires, among others. Vehicles that fail the safety checklist will not be allowed to enter the toll road, or will be asked to go out at the nearest exit.

The Southern Tollways operators hope to reduce road incidents and situations that cause delay and inconvenience to and even hurt other motorists. To ensure a trouble-free and safe travel, The Souther Tollways operators are reminding motorists to keep their vehicles roadworthy and observe tollway traffic rules and speed limits.
