Indonesia is one of the countries with the highest death rate due to road traffic accidents. Research on vehicle safety needs to be done immediately. Some travel companies, rental vehicles, and tourism vehicles have made permit speed regulations, but the basis for selecting these limits is not scientific. In this study will be presented how to determine the maximum speed allowed in a vehicle scientifically, and how to calculate the speed of the permit can be a reference to other vehicles. This research method is analytical and experimental methods. The normal force of the wheel when the vehicle turns will be different, where the normal force of the wheel inside will first be lifted due to rolling force, and will have an impact on the skid that might occur. So, this is becoming a reference in calculating the vehicle’s maximum clearance speed. The maximum speed allowed of the vehicle under study depends on the turning radius. Therefore, knowing the wheel’s normal force from various conditions and the maximum speed of the vehicle, a safety warning system can be developed in the future to avoid vehicle accidents.
