Singapore has jams not because we have too many cars, but because we have foreign workers directing traffic

My dad just fetched me home from work, and we were exiting KJC at the Woodlands road exit. I have to admit that the initial design of the junction was not fantastic. You have cars coming from the left and going towards the right, and the cars from the right, going towards the left, making the cars frequently criss-crossing. (People who use that portion will know what I'm talking about.) Then today, the turning to the left was jammed at 6pm. My father commented that it must be due to the Upper Bukit Timah Road construction where they are building the MRT Downtown line, and many big construction trucks frequently park alongside, reducing the number of lanes available for the busy traffic. He said that recently there were a lot of foreign workers holding the "Stop/Go" signs and directing traffic because of that. 

And true enough, when we went round the corner, there was a huge truck and a foreign worker directing traffic. Many Singaporeans would have been used to this sight in recent years, but my father asked one question: "Are these foreign workers actually trained to direct traffic?" Many Primary school children go to Road Safety courses conducted by the Singapore Traffic Police to learn about road safety. Do employers of these foreign workers actually send these foreign workers for training? Because the way I see it, their directing the traffic if they are not trained, will cause a traffic hazard not only to the traffic, but to themselves. Some stand in the middle of the road thinking that their lives are like that of a cat's, and that they will not be knocked down at all. 

Election is coming. I wonder if someone will ask this question to PAP. Hmmm...
