Cesar Sarmiento serves several roles in the House of Representatives of the Philippines, including Chairperson of the Transportation Committee and Vice Chair of the Welfare of Children Committee. As an advocate for road safety, he has worked tirelessly to improve the safety of children on the country’s roads. Representative Sarmiento co-authored a bill alongside the principal author of the bill (Representative Mariano M. Velarde) which was signed by President Duterte on 22 February 2019. The new law makes it compulsory for children through to 12 years to be transported in appropriate child restraint systems in all private vehicles and prohibits children 12 years or younger from being seated in the front seat of a vehicle, in line with international best practice. Representative Sarmiento also continues to advocate for the implementation of existing laws.
On 3 January 2017 the House of Representatives adopted House Resolution No. 651 which he introduced, directing responsible agencies to fully implement road safety laws on seat-belts, drink and drug–driving, speeding, distracted driving and children on motorcycles. He has demonstrated commitment to road safety not only in the Philippines, but also through global platforms. In 2018, representing the Philippines, he spoke in favour of the UN General Assembly Resolution on “Improving Global Road Safety”. During the debate, he acknowledged the difficulty of the Philippines in achieving Sustainable Development Goal target 3.6 of halving road traffic deaths and injuries by 2020 and the need to “create a culture of safety” in the country. Since 2016, Representative Sarmiento has also served on the leadership council of the Global Network for Road Safety Legislators, and through this platform he continues to be a voice among his peers from other countries.
