Vehicle Mechanical Defects (VMD) is one ofthe major cause ofRoad Traffic Accidents (RTA) in developing countries.This paper presents the quantitative analysis of RTA on Motorways in Pakistan caused due to VMD. The data iscollected from the National Highway and Motorways Police (NHMP). The Data for 1585 RTA on the Motorways ofPakistan for the years 2003-2012 were reviewed. The objective of this research was to establish the contribution ofVMD to RTA. A vehicle surve.y, based on a convenience sample of 290 vehicles was also done at the Toll plaza ofthe Peshawar-Islamabad Motorway (M-1). The response rate to the survey was 64%. The survey identified that 80%of vehicles had no maintenance record. About 74% and 65% vehicles lacked annual wheel balancing and annualwheel alignment respectively. About 61% ofthe vehicles inspected had wheel related defects and 59% ofthe vehicleshad brakefluid less than the recommended level, 20% vehicles had a brakefluid leak in their brake system, and thesemay, therefore, be at a risk ofcausing an RTA. In the RTA data from the NHMp, 32% ofall RTA on Motorways aredue to VMD and that the two vital vehicle mechanical defects (VVMD) are tyre blowouts and brake failures. Theaverage tyre burst is 17.36% and average brake failure is 5.38%. Tyre blowouts were responsible for about 55.6%of all RTA caused due to VMD while brake failures were 18% of the total RTA caused due to vital causes. RTAin Pakistan can be reduced if regular vehicle fitness check and awareness campaigns about tyre and brake systemdefects are carried out to reduce RTA.
