Road Condition
 Poor road design,
 Sample design and junction layout is not ideal, less visibility.
 Poor environment
 Example:- a flooded road surface causing a slippery roads, poor maintenance, and weather
conditions.
 Less equipment and road markings
 Signs and road lines that is not enough and not clear, and lighting is not good.
 Narrow roads cause many vehicles do not have room to move in the event of an emergency.

Vehicle Factors
 Vehicle defects

 Capacity against resistance and skid
 If the vehicle is in good condition vehicle can stop safely (tires).
 Acceleration and deceleration
 Good vehicle is a vehicle that can acceleration and deceleration quickly.
