Speed limit is the speed value enforced by the authority to regulate speed of vehicle on the road.Every carriageway has posting speed limit which is usually conveyed by a traffic signage to inform drivers the maximum speed limit allowed to travel on the carriageway. Posted speed limit is one of the most important speed limits that also indicate the maximum safe speed that can beapplied on a carriageway when conditions are favorable. This case study is carried out to determine the adequacy of the current posted speed limit set at the Kuching Outer Ring Road, Kota Samarahan, with the value of 80km/h for both directions. Radar method is used for data collection and IBM SPSS Statistics 23 is used for data analysis. There are approximately 25% vehicles of the overall traffic study did not compliance with the posted speed limit and vehicle with the highest 85th percentile speed for the studied road is passenger cars, with the value of 86km/h and 83 km/h for direction from Serian to Kota Samarahan and Kota Samarahan to Serian respectively. This shows this roadway has the need to change the current posted speed limit, increase law enforcement and also encourage public awareness on speeding dangers. Those are some possible mitigation for speeding.
