Kota Kinabalu Traffic lights not safe

Based on my investigation on the time of our yellow lights, it is designed for 25mph/ 40km/hr, not 50mph/80km/hr, that our maximum allowed speed is. In town, it is 50km/hr, suburb it is 70km/hr. No wonder there are many accidents at traffic junctions when cars are expected to stop suddenly beyond their capabilities.

Yellow Light Time Standards

Legislation mandating proper yellow light times is mostly non-existent. It is one of the goals of this project to establish national standards to protect motorists.
For the purposes of this project, we have put together a general guide to appropriate yellow light durations.
This guide is intended to help identify potentially dangerous short yellow light times. Whenever possible, suspicious timings will be confirmed by a trained, objective traffic engineer.
Recommended Yellow Light Times
Three seconds should be the absolute minimum time for any intersection.
25 MPH -- 3.0 Seconds
30 MPH -- 3.5 Seconds
35 MPH -- 4.0 Seconds
40 MPH -- 4.5 Seconds
45 MPH -- 5.0 Seconds
50 MPH -- 5.5 Seconds
55 MPH -- 6.0 Seconds


For your information, a technical explanation of the Institute of Transportation Engineers (ITE) formula for calculating yellow light times is included below (source):
