Transport Minister Piphat Ratchakitprakan ordered an investigation to determine the cause of the accident. Prime Minister Anutin Charnvirakul said such incidents happen "far too often" and called for changes to the law to blacklist construction companies repeatedly linked to fatal accidents.
Most of the injured have been hospitalized, and an emergency center was set up at the scene to assist passengers with alternative travel arrangements. Officials warned the death toll could rise.
