Speed bumps are usually painted bright yellow or another high-contrast color so drivers can spot them, and some areas even post warning signs marking their exact location. That made a video of a completely unmarked, hidden speed bump all the more startling.
Without any visual warning, the concealed bump ambushed unsuspecting motorists. The footage is a reminder of how important proper road markings are, since an invisible hazard can damage vehicles and rattle drivers who have no chance to slow down in time.
