LTA ensures safety with regular checks on buses and lower voltage charging ports
The Land Transport Authority (LTA) in Singapore has assured commuters that the USB charging ports on public buses operate at a significantly lower voltage of 5V DC (direct current), in contrast to the 230V AC (alternating current) voltage of standard electrical outlets. This significantly reduces the risk of electrocution.
As of May 2022, approximately 870 public buses in Singapore are equipped with USB charging ports, part of the country’s efforts to offer convenient charging options for commuters. LTA regularly checks on bus operators to ensure that vehicles meet safety standards through monthly inspections.
This development follows a tragic incident in Malaysia, where an 18-year-old died from electrocution after using a faulty charging socket on an express bus. In response, Malaysia has banned the use of three-pin sockets and USB ports on express buses since November 6, 2024, and will enforce stricter safety standards for electrical equipment in public transport. Malaysian operator Causeway Link, which operates buses in Singapore, has suspended the use of charging ports on its buses and is considering powerbank alternatives for passengers.
