On one hand, it is good to read the list of roads that Singapore traffic police may deploy the speed laser camera (and why do they do that?). On the other hand, it is bad because almost all the roads that I frequently use will have speed traps. The entire list can be found in the Singapore traffic police website.
I have got to be more careful when travelling in these roads: Ang Mo Kia Ave 1, Ang Mo Kia Ave 5, CTE, ECP, Kim Seng Rd, Lentor Ave, Orchard Boulevard, Scotts Rd, SLE, TPE, Upper Thomson Rd, and Yio Chu Kang Rd. There are a lot more in the polic website.
That is almost all the roads that I use on a day-to-day basis!
