Last time when they first started the signboard thingy, yeah
definitely got TP in front. Nowadays, I realise it's just total BS.
9/10 times they put the notice there bai sui only.. But just to be
safe, do not speed 
Norm when u see the car infront braked sharply (esp if u all are
speeding), most prob got TP in front...haha so dun yaya overtake
like what I did once..
