Abstract
A vehicle's conspicuity is determined by the colour and pattern of painted surfaces, height, lighting system, reflectorization and fluorescent markings. In Malaysia, the better visibility of heavy goods vehicles has to be marked with retroreflective marking. The objectives of the study to analyse percentages of marking requirement that compliant with the MS 828:2011. The study was conducted at Jawi Toll Plaza, Nibong Tebal, Pulau Pinang from 9.00 a.m. to 5.00 p.m for three days. As a result, the highest compliance level of marking requirement was 96% which is box truck two axles. Meanwhile, other categories were between 17% to 91%. Many HGVs were not installing rear-end marking type 5, while all trucks and trailers with a maximum gross vehicle weight (GVW) of 3500 kg and above had to be marked with Type 5 (contour marking) as of 1 July 2019. Some improvement needed to reduce the severity and the number of road accidents by recommended a safe following distance.
Highlights
Conspicuity issues may contribute to the rear end and underride truck accidents
The rear markings effectively illuminate the outline of a vehicle at night by reflection from the headlights of vehicles following behind
In Malaysia provided five types of the rear and side marking specified by Malaysian Standard (MS) 828:2011
Summary
Conspicuity issues may contribute to the rear end and underride truck accidents. Rear-end truck crash happens when heavy trucks are driving at a slower speed than other vehicles. This high-speed differential between heavy vehicles and other vehicles will lead to possible collisions on the rear end [1]. Conspicuity plays a significant role, mainly involved in the accident at night. Bad visible of the night's rigid or articulated truck where drivers failed to see the truck turning off on the road, turning and driving ahead [2]. The truck can be more visible by labelling retroreflective labels on the sides and rear of commercial vehicles
