Currently, there is no official statistical data clearly indicating which specific car model has the highest collision frequency in Malaysia. For example, in a recent serious accident involving a trailer truck on the North-South Expressway, the involved vehicles included a Toyota sedan, a Proton SUV, and a Honda SUV, which indirectly reflects the high prevalence of these brands on the roads. The causes of accidents are mostly related to driving behavior, road conditions, and vehicle maintenance status, rather than a single model defect. Local best-selling models like Perodua Myvi and Proton Saga may have a high absolute number of accidents due to their large ownership, but objective evaluation of the collision rate requires combining data such as mileage. It is recommended that drivers regularly check key components such as tyres and brakes, and adhere to traffic rules to reduce risks.
