Nung papasok ako sa NLEX kahapon (from Balintawak), may nakita ako na sign dun sa right that says something like this "NO BRAKES? Go here". Tas nung tiningnan ko naman, parang gravel pit/road lang naman.

QUESTIONS: How does this work? Does it even work? Ano yun, kapag nawalan ka ng preno, kakabig ka patungo dun and some unknown device would stop the vehicle from moving?

'La lang, curious lang ako.
