I experience tons of road blocks.
Raodblocks I know of:
The road behind Marina Sq, leading to ECP.
Nicoll Highway(speed trap)
Whampoa
AMK Ave 1,3,5
Expressway also have, think is AYE
Jurong town hall
TP raodblocks usually catch tinted visor, exhaust pipes, sticker
license plates, insurance, valid license, drink and drive.
NPP raod blocks usually check road tax and insurance and valid
license.
Usually operate ard 2-4am, Fri and Sat nites.Thats where most ppl
finish clubbing and alot of drink and drive.
