The group announced on Facebook that its protest on Saturday will be themed "Meteor strikes dinosaur".
To avoid being caught in jams, police advised people to avoid Rajdamri Road (Rajdamri-Pratunam intersections), Rama I Road (Chaloem Phao-Ratchaprasong intersections) and Ploenchit Road (Ratchaprasong-Chidlom intersections).
Police have recommended using Ratchaprarop Road, Phetchaburi Road, Phya Thai Road, Rama IV Road, Henri Dunant Road, Sarasin Road, Silom Road, Sathon Road, Witthayu Road, Sukhumvit Road, Soi Tonson and Lang Suan Road.
Earlier on Thursday, the Bad Student group said the aim of the rally was to remind lawmakers that if they don’t change their dinosaur-like outdated mindsets, they would be hit by meteors.
