We refer to Mr Thomas Lee Chee Chee’s letter “Paint speed limits on roads” (Straits Times, 30 Dec 2014).

Speed limit markings have been painted on some roads, such as Orchard Boulevard and Lornie Road, to remind motorists to observe the speed limit. LTA is monitoring the effectiveness of these markings on driver’s behaviour and will consider implementing the markings at more locations.

Currently, all road markings are already painted with reflective paint. However, due to weather conditions, reflections from wet road surfaces may prevent motorists from making out the road markings clearly. The reflection from wet road surfaces may also cause the road markings to be less obvious at night.  

We have thus been studying different ways to improve the visibility of our road markings when it rains, including trying out  a new reflective paint material to enhance reflectivity of road markings that Mr Lee referred to. The results of this trial showed improvements, and we will progressively use this new reflective paint material as part of our road maintenance programme. 

We thank Mr Lee for his feedback.
